Similar to P brighamii but it is a larger pant with different shape to the sepals and lip. Also similar to P corniculata but it also has differently shaped sepals and lip." Ames & Schweinfurth 1925

"Characterized by the caespitose habit with leaves up to 3.2" [8 cm] long, and less than .6" [1.5 cm] wide and the peduncles up to 4" [10 cm] long. The flowers are produced successively in a fascile of congested [edicels at the apex of the peduncle. The lateral sepals are partially connate with the lateral margins revolute and glabrous, the petals are dilated on the labellar margin and the lip is oblong with erect marginal angles below the middle and a pair of spiculate-denticulate calli."
