The above species appears to be the first member of the 
Farinosae (in the restricted sense) to occur in Yunnan. Its 
nearest ally is P. Knuthiana, Pax. ‘The variation in size in the 
various specimens collected is remarkable—from dwarfs of an 
inch in height to plants of 20 inches. The bracts on the 
inflorescence do not all spring from the base but are arranged 
in a spiral series—and naturally the pedicels likewise.
