Stem (including the terminal peduncle) often 1 foot, grooved, hollow. Eadical 

 leaves (including the petiole) 3-4 by 1 in., in Sikkim examples twice as large as Nipal 

 <*nes; pinnae 7-11, segments oblong toothed or lobulate. Bracts 'of a dilated 

 narrow oblong entire petiole and sub-bipinnate limb with narrow remote segments 

 ]n Sikkim examples, ovate pinnatifid with approximate broad lanceolate segments 

 in Nipal ones. Fruit ^ in.; style-bases conical, prominent; primary ridges lax; 

 pericarp thin, somewhat inflated ; vittae usually 2 between the primary ridges ; 

 ^rpophore 2-fid. Seed semiterete, dorsally subcompressed, hardly concave on the 

 inner face. •
