 rounded; nerves strong, close-set, subhorizontal or ascending, not arched; petiole 

 J-§ in. ; stipules J in., ovate, lax, entire or 2-3-cleft. Cymes 2-3 in. diam. ; peduncle 

 stout, 4 in. or less; branches whorled or opposite, together forming a flat-topped 

 corymb ; bracts and bracteoles minute, caducous ; flowers minute, subsessile. Calyx

Branches very stout. Leaves 6-14 by 3-6 in., pale when dry, coriaceous ; nerves 

 strong, arched; petiole J-l}in. ; stipules 1 in., broadly ovate, often cleft. Cymes 

 2-4 in. diam., pubescent or puberulous ; peduncle 3 in. and less, very stout ; branches 

 usually whorled, very stout, forming a corymb, spreading or deflexed in fruit ; bracts 

 and bracteoles minute, caducous; flowers small, pedicelled. Calyx obconic; limb 

 ialmost truncate. CoroUa-tabe very short, throat with an exserted brush of erect hairs. 

 ■Fruit ^— J in., base rounded, smooth ; pyrenes semicircular in section, quite smooth. 

 Seed ventrally flat. — My own Khasian specimens have large ovoid fruits with no 

 "trace of a ventral groove in the seed and corymbiform cymes. Cachar ones from 

 Keenan have a more irregular cyme, with smaller broader fruits and a deep T-shaped 

 ventral groove, which, however, sometimes quite disappears. This species very closely 

 resembles P. fulva, differing in the ebracteolate flowers and in the fruit.
