Anderson, Edward F. (Whitman Coll., Walla Walla, Wash.) A revision of Ariocarpus (Cactaceae). III. Formal taxonomy of the subgenus Roseocactus. Amer. Jour. Bot. 50(7): 724–732. Illus. 1963.—This is the first of 2 articles dealing with the formal taxonomy of Ariocarpus. The introduction contains sections on geographical distribution and habitat, policy of classification, and herbaria consulted. Acknowledgments are made to those who assisted in research or field studies. A description of the genus and a key to the subgenera and species is followed by a formal taxonomic treatment of the subgenus Roseocactus. This treatment includes a description, illustrations, a map of authenticated collection sites, citation of common names, a discussion of synonomy and types, and a list of specimens examined of each species and variety. The accepted species which are discussed are Ariocarpus kotschoubeyanus and A. fissuratus. The latter species consists of 2 varieties, var. fissuratus and var. lloydii.
