Leaves 25-30 em. long, 7-0-9-5 cm. broad; petioles 10-20 mm. 
long. Sepals 2 exterior + 22-28 mm. long, interior 3 em. long. 
The distinguishing features of this species are the large oblong 
leaves with numerous glands and with numerous lateral nerves which 
are about 2 mm. apart, and the exterior sepals 22-28 mm. long. The 
leaves are larger and the exterior sepals shorter than in P. butyracea 
Sabine (Hooker's Icones, t. 2465).
