719. Denslow, H. M. Further reflections of an orchid-hunter. Jour. New York Bot. Gard. 21: 145-156. 1920.—The orchid flora even of the eastern states is not yet well known and much more information is needed on the life histories of various species. Herbaria do not contain sufficient specimens to indicate geographical distribution accurately. Field work on orchids must be prosecuted promptly and actively, since the orchid flora is rapidly disappearing.—H. A. Gleason.
