A very distinct species; ngreeing, except in the absence of stinging biistlcs, a» 

 regards foliage and habit with T. Wildemanii, Beille, but differing in being 

 diooecious, in having a 6-partite female calyx and in having solitary male flowers.

 puberulous and sparingly armed with stinging hairs. Leaves sessile or

 witii mucronulate tip, base shortly cuneate, or rounded, margin spar- 

 ingly serrate towards the apex, elsewhere entire, 1^-2 in. long, J in. 

 wide, very sparingly shortly setose on the nerves on both surfaces and 

 along the margins, otherwise glabrous ; petiole 0-2 lin. long, sparingly 

 setose and bristly ; stipules lanceolate, under 1 lin. long, rigid, reflexed, 

 rjlabrous or sparingly shortly setose. Racemes 1-sexual, dioecious, 

 terminal on stem and branches and below leaf -opposed ; male racemes 

 6-10 in. long, with a naked peduncle 2 in. long, thinly puberulous and
