A taxonomic review is presented of the taxa of the genus Cyrtopodium R. Br. ( Orchidaceae ) recently described by L. C. Menezes. As the types of most of the names of these taxa are vegetative specimens, and therefore generally useless for specific recognition, the authors designate epitypes for eight of them: C. aureum L. C. Menezes, C. braemii L. C. Menezes, C. caiapoense L. C. Menezes, C. cipoense L. C. Menezes, C. fowliei L. C. Menezes, C. holstii L. C. Menezes, C. sarneyanum L. C. Menezes, and C. withneri L. C. Menezes. Furthermore, C. sarneyanum L. C. Menezes, C. paludicolum var. goiandirense L. C. Menezes, C. paranaense var. pickelii Hoehne, and C. vernum var. fulvum L. C. Menezes are placed in synonymy of C. braemii L. C. Menezes, C. paludicolum Hoehne, C. andersonii (Lamb. ex Andrews) R. Br., and C. poecilum Rchb. f. & Warm., respectively. Since the distribution of terrestrial species of Cyrtopodium is strongly correlated with soil type, soil humidity, and surrounding vegetation, comments on habitat preferences of most species are also given.
