A large woody climber, with membranous young- leaves growing

 very small, green, in irregular corymbose very slender-branched

Purneah, near the Nepal boundary ! Fl. May. Deciduous March- April. 



Attains 1 ft. girth in our area with nearly smooth bark and rather hard cream- 

 coloured blaze with deep yellow streaks. Leaves with obtuse or usually rounded

 from close to the base, nervules minutely reticulate, enclosing pale areoles beneath

I assign all the sub-Himalayan specimens of P. (oriacea to P. scandem, including 

 Hamilton's specimen from Nathpur (quoted by Clarke under P. coriacea and 

 Wallich's P. ramosa. No. 1774). It is significant that all the fruiting specimens., 

 are classed under P. coriacea at Kew, but the leaves being older are naturally moi'ej 

 coriaceous.

 A huge woody climber with oblong, broadly oblong or ovate, caudate' 



leaves 3-7 "5" long, rounded or cordate at the base, youngest only
