Branches robust. Leaves very variable, 6-7 by 2-23 in. in the oblanceolate forms, 
8-10 by 4-6 in. in the broader forms, pale green or dark when dry, base acute or 
rounded; nerves strong, close-set, subhorizontal or ascending, not arched; petiole 
4-4 in.; stipules 2 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 
hemispheric; limb truncate, obscurely toothed. ^ Corolla-tube very short, throat 
villous. Fruit } in. diam.; pyrenes semi-circular in section, quite smooth. Seed

Branches very stout. Leaves 6-14 by 3-6 in., pale when dry, coriaceous ; nerves 
strong, arched; petiole 1-1] 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 
almost truncate. Corolla-tube very short, throat with an exserted brush of erect hairs. 
Fruit 1-Y 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.

A small subherbaceous species; branches slender, soft. Leaves 3-7 by 1-3 in., 
usually pale green when dry; nerves slender, arched ; petiole 4-14 in.; stipules in,

very short and the seed not concave ventrally.
