His home country, the Tennessee Valley, laud scarcely been.mentioned in publications in respect to algae, although excellent studies in other'plant groups had been made there, revealing a most interesting flora. The search for reference material naturally led to observations of studies made of the entire region, Southeastern United States. It seemed easy'to understand, at first, why so few studies had 'been made. There was no 'Small's ManuIl" for the algae, and the existing literature was scattered and not easily obtainable. -Further- more, as a group, the algae seemed to require a greater degree of perception, judgfiment, and discrimination than many other plants. Nevertheless,so many interesting possibilities for investigation appeared that a study of some phase of the algae seemed very worth- while. During the writer's four year's absence from civilian life, several good and substantial papers were contributed toward a knowledge of the phycology of the Southeast, and the writer felt that a greater purpose could be served by integrating available material along with his own contributions rather than concentrating on an intensive study bearing little relation to other studies. Perhaps it was both an individual Ifldlosophy of interest in the broader aspects of knowledge, and a plain regional pride that prompted a study encompassing approximately the southeastern quarter of the country. The method of approach used was to find out what species within the a On: 3 _ I'In ‘lirlllllil'Vlillllxra. .Il‘itl r . If v . . .a v,‘ “N 2 heterogenous assemblege called algae had been found in the region, where, by whom and when. Very soon a study of synonomy became necessary in order that the data should become meaningful, and finally it became clear that names were only as good as authorities made them and should, therefore, be linked to a concrete reference by a leading authority. About twenty-five hundred species and varieties, the largest number to have been included in a single American study, have been considered by the writer for the attainment of the objectives stated below. There have been three main objectives in the study: (1) To obtain a distributional pattern of the species reported from various sources, so as to furnish a base for ecological and geographical studies for the writer and other students in the future. (2) To interpret the nomenclature used in the light of modern opinion, so that there may be less confusion and duplication than now exists in the literature of the region. (3) To make a contribution toward more complete information on the algae of the region in the belief that a perspective of lmowledge can be obtained from a broad view which will be of aid to more intensive studies . The degree of attainment of the first objective was limited by its very enormity, and the lack of a record which would support valid con- clusions about most of the species. Although the real work of inter- pretation must wait, the distributional data presented here will be an aid toward future ecologial study. Presented here for the first time is 3 the known distributional pattern of every species reported from a broad area of the United States. The other objectives are believed to have been achieved to a more exact degree. Almost every name has been referred to a recognizable entity vouched for in a modern standard publications by the leading authors in the field. It is recognized that most taxonomic studies have and will continue to look to these larger volumes by leading authors, rather than to original sources, for identification and interpretation, so what might be termed, "Authoritative references,“ are listed inmedi- ately after species names. It is true, to be sure, that some of the authoritative references used are not yet published, one, G. W. Prescott's Desmid Iconograph is not of a publishable nature, and, furthermore, other authoritative references are to articles in journals. The last stated objective, 9. synthesis into a broader piece of knowledge, involved some compilations. It was fully realized at the beginning of this study that compilation is chiefly a dulltask at times, looked upon with high disdain by judges of research standards. The writer was fully convinced, however, that in any field of study "ti-”rout" must be taken occasionally to put the field in order. It is true of the phycology of the Southeast, as it is true of many other Portions of, biology, that the snarl of synonomy and the pure weight of numbers and inaccessability of various contributions tend to make study, "9”le by a young student, thoroughly discouraging, and even the Oxpert PTObably finds the field completely cumbersome. In the following pages are almost twenty-five hundred species known a.“ tbs Southeast including many unpublished reports from collections, ”m °f 'hich were made by the writer during 191.1-2 and 19h6-7, and ot - he" “11311 were observed in the herbaria of the University of Tennessee "' a- .0..,‘ I‘ 1 ‘_1M m4: ‘0. q h and the Chicago Museum of Natural History. In the literature, direct references to Southeastern algae number over one hundred. In addition there are several works which have at least an indirect bearing on the algae of the region and are, therefore, necessary references for corrobo- ration of species. The arrangement into families most nearly approximates Smith (1938) but includes judgements made from the publications of Fritsch and the Pascher series of handbooks. Within the family, genera are listed in alphabetical order. for convenience. An explanation of the form, symbols, and abbreviations found in this writing will be found in the-Imasection.

' H '4 5 A REVIEW OF FRESH-MTER PHYCOLOGICAL RESEARCH IN SOUTHEASTERN UNITED STATES The real beginning in research on fresh-water algae of southeastern United States, although incidental reports have been made previously, was the trip which Jacob Bailey took for his health during the winter of 18349-50. This professor of Chemistry at the United States Military . Acadesw enjoyed his trip and related the pleasure of being in the collecting grounds of South Carolina, Georgia and Florida in a personal chatty manner that has at some time since then disappeared from scien- tific literature. His microscopial observations, published in the second volume of the Smithsonian Contributions to Knowledge (1851), included not only fresh-water forms, but marine as well and some organisms that are now considered definitely of the animal kingdom. hon sixty sites, only a half dozen filamentous m were listed under the name “Algae", but there were over one hundred desmids and about the same number 'of diatoms, less than a quarter of which were fresh-water forms. Bailey had hopes that his beginning would stimulate further re- search. As he put it in his introduction, "I offer the following notes, 31°ng that if they have no other interest they may serve to point out 150 the southern naturalists, and the numerous intelligent invalids who hibernate in the South, how rich a field of amusement and instruction Mounds them even in mid-winter." It took over eighty years for the southern naturalists to accept fully “‘9 Suggestion for further study, although in the meantime, they comm6d for outside naturalists who have contributed to the knowledge 01‘ southeastern algae. At present almost twenty-four hundred algae, “eluding all classes, have been added to those on Bailey's list, . ‘17.: ‘1, a u~;r» V" O .OI- w LO». I... . u , A \ 0‘ be '5 M - 0.. b I: . "I «1 O...“ ‘I- 3‘" "0.. “-1 6 although certain groups have been neglected. In the case of the diatoms it was not until 19M; that a list ,longer than Bailey's,of fresh-water forms from the section was published. The area here called 'Southeastern" includes the ten states making up the southeastern quarter of. the country. Virginia and Kentch are included and form the northern boundary, and the Mississippi River is the western boundary although the whole of Louisiana‘ is included. Florida, for climatic reasons appreciated by Professor Bailey and since expounded by the Chamber of Commerce, has received by far the greatest attention, and Alabama the least. Of the different groups of the algae which are most common in the Southeast, the Desmids, partly because of their aesthetic qualities and partly because the acid swamps of Florida are a favorable hunting ground for then, have been studied most and the diatoms, as previously mentioned, the least. There were no sectional studies in the Southeast during thelast half of the nineteenth century, which, it seems hardly necessary to state, included the Civil War and Reconstruction. In this period, how- "91': was the first attempted comprehensive treatise on American fresh- ‘mr algae, a report by Dr. Horatio Wood in 187b, in which the southeast '35 rePresented by collections made for the Philadelphia Physician and BOt‘m-‘t by Dr. J. S. Billings of the Army in Florida,and:PYrofessor Ranml 01’ South Carolina. The latter collector sent Georgia and Texas Muriel in addition to that from his own state. Wood freely asserted “‘1" he did not go over all of Bailey's papers, but he did include the «m3 31‘0“ the 1850 observations. n" ”00nd comprehensive American phycologicsl study was the Rev. M“ 'Olle'. Fresh-water A_l£a_§ 95 the United States, 1887 and his l i ..I 7 Desmids of _t_h_e_ United States, 188).; and 1892, the third of the foundation stones upon which later workers in the Southeast might build. Ravenel, of South Carolina, again made many of the collections for Wolle's publi- cations and a Captain J. Donnell Smith sent over seven hundred specimens from Florida. About these Florida collections, Wolle remarked that although desmids were not numerous, there were species included which were not found elsewhere. Wolle' s observation on “specimens not found elsewhere' is still a .valid statement for Florida desmids. In spite of the considerable attention that they have received, an examination by the writer of only ten collections included twenty-five not previously re- ported from the Southeast and possibly up to five new species or varie- ties. It seems a bit strange thatillonnell Smith' 3 Florida collections did not contain numerous desmids, since subsequent collections from soft water sites there contain such a rich variety and huge quantity as to amaze observers, among them the Wests of England who published in 1898 a list of some desmids of the United States, using material which had been sent by Wells. Florida algae were again considered by a foreign writer, Barge of Sweden, in 1909. A substantial number of his one hundred and fifty listed species were desmids, as might be expected. After Barge, it was not until. 1930 that another list of Florida “Nd-8 was published,by Helen Jean Brown of Ohio State University. Th1! Paper, Desmids 2; the Southeastern Coastal Plain w 9; 3.11.2 vii—ESE m, is a notable one. It was the first of the present ”rice or writings by various phycologists which is building toward a mbetantm knowledge of the algae of the region. And it was the first re1’01‘15 for the area to attempt an interpretation of the algal flora in 1"lation to ecological factors. In addition to the Florida desmids, Bram mam desmids m from Louisiana, Mississippi, A» 8 Alabama, and Montvale Springs in Tennessee, which, however, is not in the coastal plain. Studies of Florida desmids also were made by Johnson, 1895, Salisbury, 1936, and Whelden, 191d, and they have also been included in the treatises on the genera Micrasterias and Euastrum, in l9h2 .and 19145 respectively by Prescott and Scott. Florida is also the subject of the only other algal group study lads in the Southeast; the Oedogoniales of Florida by Tiffany in 19th. The only Southeastern papers on soil algae, Smith and Ellis, l9h3, and Smith, 19%, are from there, and endophytic and pathogenic algae have received attention too. Early collections were made in the state of Virginia by L. D. van Schweinits between 1812 and 1821 (Drouet,. 1938),“ dwglle observed Virginia material WW, fthere were no further reports until aha; % 9; Charlottesville and Vicinit , Lewis, Zirkle, and Patrick, 1933. The Oscillatoriaceae of that state were covered by Strickland (19140) who has also written on the entire Myxophyceae group, but does not, at this writing, consider his work ready for publication. North Carolina ranks after Florida in the extent of publications f°r any one state and has consistantly been the chief center of research “thin the Southeast. One of the two efforts to write a state fresh- “tar a188-3..flora was made there in a doctor's thesis by L. A. Whitford, now of North Carolina State College, in 19142, after he had previously “'1th of some rare and little known species of North Carolina. Whit- ford mued some diatoms. The only other recent list of algae of any ‘1“ 18 included in Philson's study of North and South Carolina algae, 1939’ but 3Pecies from the state have been mentioned in various places, mm”? a report on a lake study by Brown in 1911, and Josephine U I .a‘ |-~1 r snet slum. 0, .fl 1, nd . 'HI '4‘ 9 Tilden's American 5.1.8.32 in 1898. Even earlier, 1888, Poteat had described eighty desmids from a limited region in Carolina. In the near future E. C. Cocke of Wake Forest College is scheduled to publish the results of his intensive studies on North Carolina Myxophyceae, making another substantial contribution to the knowledge of the algae of the state. South Carolina algae had been included in published reports since the early days because of the collections of Ravenel, and more recent studies have been made by Philson and by W. C. Frohne, 1939. Reports from Georgia in this century are limited to the 1939 and 191:2 papers of Frohne. Most of the knowledge of Kentucky algae is contained in the various papers by B. B. McInteer, beginning with a preliminary report. in 1930 and including a survey as a doctor's thesis in 1933. One of these papers related the distribution of algae in that state to soil types. Kentucky algae are also considered by Bailey in his papers on Chroococcus and filamentous Myxophceae, -Lillick and Lee 1931;, and Brinley and Katsin, 191,2. In Tennessee, after the study by Brown in 1930, there were subse- quent Papers in connection with Reelfoot Lake studies, a general crypto- 8’“ paper by Schwartz in 1933 , in which only genera were identified, “‘1 a Plankton. study by Eddy, 1930. Lackey in his plankton studies of the Tennessee Rivers included the second recent listing of diatoms of the southeast. In 19h1, the writer made collections in the Great Smoky Moun— t‘in‘ 01' Eastern Tennessee which were identified by Dr. Francis Drouet “‘1 D" Ruth Patrick. Although there were only a hundred species in the limited survey, fifteen of these were rare, or had not been reported from u” Smtheast, and the examination of only a few 19146 collections revealed e izht more. The Tennessee specimens give a hint of the rich possibilities 10 for study. The papers of Lackey (l9h2) and Brinley and Katzin (191m) deserve a special mention: 5t only because they contain diatoms, but include a host of exceedingly rare planktonic forms. It is most unfortunate that species authors are not listed and so several names are difficult or impossible even to verify. Mohr's Plant .Life of Alabama, 1901, contained some algae, Brown in 1939, and Collins in 1909, mentioned some Alabama species and there were reports on the red algae which shall be discussed separately. For Mississippi, there are the 67 species listed by Brown and a 191:2 paper by Prescott and Scott, which describes close to two hundred desmids. From Louisiana, we have Prescott's paper on the algae of Louisiana in 19,42 and the record of some Zygnemataceae and Oedogoniaceae by Taft in 1%. Taft' s study is the latest addition to the considerable number of papers on Southeastern fresh-water algae by representatives of Ohio State University. These include Brown, Whitford, McInteer, Salisbury, Transeau, and Taft. Louisiana is the scene of studies now in progress on fresh-water red algae. Dr. Lewis H. Flint, of Louisiana State University, who has con- tributed two papers recently, is the only active American specialist in this field since 0. Marvin Palmer of Butler University is in India. The contribution of Palmer has been considerable, and he hopes to resume his work on his return, according to a conversation before his departure. At “‘3 the. he expressed an interest in correlating the distribution of Q2 '1‘“! geological formations and other factors in Kentucky and Tennessee. Borers Palmer took up the study of 1%, there had been no original rePorts of red algae except for a single mention in Collins, #,._-~.'._~e ~ v'- ‘1'.“ 11 1909, and George F. Atkinson's posthumusly published notes, 1931, since Rev. Cox identified a half dozen from Alabama in 1901. The‘ foundation for a study of the Lemaneacea had already been firmly laid by Atkinson in his excellent monograph in 1890. Most of the Southeastern States contributed specimens which were mentioned by him. Still earlier, the type specimen for the genus ‘l‘uomeza had been collected in Alabama and named by William Harvey for Professor Tuomey of the University of Alabama. Group studies by two investigators have included a liberal sprink- ling of Southeastern records. Tiffany's monograph, the Oedogoniaceae, 1930, and % Oedoggn_iales 2;: North America, 1937, especially the latter, contain mentions of collections from half of the southeastern states, as does 1‘2 Fresh-water Cladothraceae by H. Phinney, 19115. For no group of algae, however, is there a general comprehensive work which can serve as a ready reference to the Siutheastern ycologist. It is true that the somewhat cosmopolitan nature of many algae makes it possible to use a combination of well written and illustrated manuals coupiled for other sections of this country or for foreign countries. Although as high as four-fifths of Southeastern species in certain groups, '87 be found in these works, in no case is there a very high degree of correlation between the total algal flora of the region covered by a Iannal, and the Southeast., .For instance, most of the recorded South- “stern species of a given Cyanophyta group may be found in the writings 0f Geitler or Franny, but they must be sorted out from among many others. Whel‘ research may reveal a higher degree of correlation between '13” °f [the Southeast and published floras than appears at present, but enough differences are indicated that a general comprehensive work of o utheaetern algae seems desirable. There is every indication, 110“”?! veu'wv’V-‘m. .4» lei “. He‘l ‘ni‘i‘ .|‘ll I u -0. I" 12 that not only is the primary task of identification a long way from a reasonable degree of completion, but also that the ecological picture, which.night we11.be an exceedingly interesting one, is scarcely taking form. Therefore, the time for a general comprehensive writing on South- eastern algae has not arrived. Several more studies must be added to those already made, and then the desirable, and much needed, compilation should follow as a matter of course. 13 EXPLANATION OF USE AND ABBREVIATIONS The use of this writing can best be explained by referring to the hypothetical gangevziven below, because none of the actual cases cover all of the abbreviations oanmonly required. 3.13.3.

MICROCYSTIS Kuetzing 1833 The revival of Polycystis to replace the name most common to the literature of this century is explained in Bailey, 1942, but a discussion of the reason why this name, too, is “~- valid is given in Prescott. Diplocystis is the 1{?;est legal heir to be brought forward, Drouet and Bailey, 1948. Because various species are in the process of being assigned to dif- ferent genera, those for which there is no record of transfer are simply retained here for the sake of order. Microcystis aeruginosa (Kuetz.) Elenkin (Prescott (f)) (Smith (f) etc. with authorship Knots.) see POLYCYSTIS AERUGINOSA Kuets. Presumably this will become Diplocystis aeruginosa but such a name has not been published. Microcystis aeruginosa var. major (Wattr.) G. M. Smith (Prescott) see POLICYSTISNAERUGINOSA Knots.

Drouet and Dail§y have followed Elenkin, the monographer of the group in including this species with Microcygtis aeruginosa (Kuets.) Elenkin, but Prescott feels that the question is still Open since there are in nature two appar- ently distinct colony forms, globular and compact ones being typical for 15. flos-aguae: clathrate and perforated ones for g. aeruginosa.

Neither a description nor an authoritative reference has been seen by the writer. Microcystis pulverea (Wood) Forti see DIPLOCYSTIS INCERTA (lemm.) Dron. 4 Dell. This transfer is made on the basis of the statement in Bailey, 1942, which is reiterated in hescott, that Hierooystis incerta Lemm. has popularly been reported as liicrocystis mlverea. Drouet has replaced the latter by Diplooystis incerta. 10. Microgysti, .tagnalis Lemm. (Geitler, 25) see DIPLOCYSTIS INCERTA (Lemm.) Drou. A Dail. Again, this transfer is because the species is considered 33 a synonym of Microcystis incerta Lemm. by DailAy, 1942. POLXCYSTIS (obsolete) The use of this generic name was revived and explained in Bailey, 1942, but subsequently has apparently proven to be invalid.

DERMOCARPA Crouan 1858 This genus is in a separate order (Dermocarpales) and family, which included Clastidium, according to Geitler, 1925. 1. DERMOCARPA GARDNERIANA Drou. (Drouet, 1942) FLORIDA Drouet, 1942 . PLEU'ROCAPSA Thuret 1885 In Geitler, 1925, this genus will be found in Pleurocapsales (Pleurocapsaoeae) which includes yells, mcobyzsa and other genera. However Dailey included the genus in the Chroococcaceae. mviously, a careful study of and a complete redistributiOn within this entire group (Cocoogonese)is highly desirable. 2.

BEGGIATOA (bacterial) This genus is now understood to be bacterial, whereas at one time this species, at least, was considered an Oscillatoria. DeToni, Syl. Algorum, 1889 referred the species below to Oscillatoria leptiformis Kuets. Fritsch II says that the genus is not like Oscillatoria and implies bacteria, and Drouet is of the opinion that bacteria were collected when this genus appears in published lists.

Lagerheim 1888 This genus has been the subject to an intensive study recently by Mrs. Grace Phinney, who has concluded that there are only four distinct entities in the genus; g. m, g. Wittrockii, E. staggorum, and g. tenerrima, with perhaps a variety of E. Wittrockii. In spite of his limited experience with the genus the writer is inclined to agree with Mrs. Phinney to a great measure on the basis of conversations and some observation of her notes. Therefore, an attempt is made below to interpret the species in the light of Mrs. Phinney's con- clueions. Since the interpretations are partly the writers, they must be considered all the more tentative. MICROSPORA AHOENA (Kuetz.) Iagerh.

Whitford found oil rather than starch, two membranes on the oospore, 181 not differing too much from some other species, and pointed out at least two other species have practically beakless oogonia. Therefore, the erection of vaucheriopsis is not justified in his opinion. The writer has found no further discussion on the subject. I§¥I£1.2 Phyllosiphonaceae PHYLLOSIPHCN Kuehn 1878 l.

The use of granulatum as a variety name by Whelden over- looked the previous use of the name, and is incorrect. The writer does not believe that another variety name is nec- essary, however, inasmuch as he has compared Whelden's drawing and description with that of the Ralfs variety, at least as interpreted by Irenée-Marie, 1939, and making allowance only for the scale of the drawings, they seem to check remarkably well. The unlikely case seems to have occurred in which the same name was used for the same variety almost a hundred years apart. 13. PLEUROTAENIUM EHRENBERGII var. UNDULATUN Schaar.
