idote dorsally, about 3.5 mm. long and 2.5 mm. broad. 
Petals broadly ovate, obtuse or acute, slightly oblique, 
3-nerved, about 8 mm. long and 2.5 mm. broad. Lip 
obscurely 3-lobed, saccate, about 4 mm. long and 2-38 
mm. broad, with two prominent mammillate calli near 
the small lateral lobes and a central thickening near the 
base in the sac; lateral lobes small and obscure, near the 
middle of the lip; mid-lobe strongly reflexed, slightly 
retuse, quadrate, about 2 mm. long and 2 mm. broad. 
Column about 2 mm. long, with a broad wing on either 
side. 
Pholidota Schweinfurthiana is very closely allied to 
Pholidota pectinata Ames and might easily be confused 
with that species on a superficial examination. Pholidota 
Schweinfurthiana may be distinguished from P. pectinata 
by the following characters: 
P. Schweinfurthiana 
Calli of lip mammillate. 
Lip obscurely 3-lobed. 
Mid-lobe of lip no broader than 
the basal half of the lip. 
Sepals and petals comparatively 
broad. 
Raceme of flowers markedly 
fractiflex. 
P. pectinata 
Calli of lip elongated. 
Lip simple. 
Middle part of the lip much 
broader than the basal half, 
nearly twice as broad. 
Sepals and petals comparatively 
narrow. 
Raceme of flowers not markedly 
fractiflex. 
It is indeed a pleasure to name this species in honor 
of my colleague, Mr. Charles Schweinfurth, who, several 
years ago indicated its distinctness. 
Borneo: Gunong Temabok, Upper Barami Valley. At 4000 feet 
altitude. November 5, 1920. Moulton 6678, (Type in Herb. Ames
