CORYPHANTHA. 37 lowish, 10 to 12 mm. long, rigid, tomentose when yomig; flowers lemon-yellow, with outer segments tinged with red, about lo cm. broad, the segments narrowly oblong to spatulate, acute, somewhat toothed toward the apex. Type locality: Mexico. Distribution: Central Mexico. It is difficult to ascertain what the true Mammillaria radians of De CandoUe really is. The type plant was described from specimens collected by Thomas Coulter, probably in eastern Mexico. We believe that specimens collected by Dr.

The type plant was described from specimens collected by Thomas Coulter, probably in eastern Mexico. We believe that specimens collected by Dr. Edward Palmer near San Luis Potosi, Mexico, represent the species as well as any plants we have yet seen; these, however, are cespitose as well as solitary. The species seems nearest Coryphantha compacta. Cactus radians pectinoides Coulter, based on Eschanzier's plant from San Luis Potosi (1891), we have not seen but suspect that it belongs Fig. 34.—Coryphantha radi: , afcrrai,.

Coryphantha impexicoma, credited to Lemaire, is given as a synonym of Mammillaria cornifera impexicoma Salm-Dyck by Riimpler (Forster, Handb. Cact. ed. 2. 414. 1885).
