Pachystoma (Greek, meaning thick mouth, referring to the thick lip). Orchidaceae. Terrestrial orchids with leafless scapes from underground nodose rhizomes: pseudobulbs producing 1-2 lvs.: sepals and petals similar, the lateral sepals occasionally forming a chin, all upright; labellum 3-lobed, forming a sack with the base of the column; anthers bent over; pollinia 8, lying in pairs and bound into 4 by elastic threads. About 10 species, chiefly E. Indian and Malayan, but 1 from Trop. Afr. P. Thomsoniana, Reichb. f. (Ancis- trochilus Thomsonianus, Rolfe), is the most commonly cult, species. It has large fls. with white sepals and petals, and the lip has green erect side lobes thickly dark purple-spotted and a narrow recurved midlobe which is white nearly covered with deep purple lines. Trop. Afr. —A warmhouse plant. P. Thomsoniana is now referred to Ancistrochilus by Rolfe. Ancistrochilus has 2 species and is readily distinguished from Pachystoma by the pollinia being united to a single stipitate appendage as well as by the remarkable lip and spreading segms.CH
