Chas E. McRAY, Canon City, Colorado, sends us a beautiful-looking blossom, which he describes as follows : — It is in blossom all summer, and bees work on it almost as they do on mignonnette. Canon City, Colorado. Chas. E. McRay. As it was beyond our experience, we sent it to Prof. Beal, who names it as follows : — This is Petalostemon macrostachyus. I have had two other species sent in as bee-plants. It is nearly related to the clovers, and several of them are called prairie clovers. W. J. Beal. Agricultural College, Lansing, Mich., Nov., 1881.
