 slender, terete, sulcato-striate when dried, green in recent, 

 retrorsely pubescent but hairs denser towards the young point. 

 Leaves alternate, petiolate, cordate with rounded lobes and a 

 widely open sinus at the base, mucronato-acute at the apex, 

 entire and ciliolated, peltate at the base, thickly membranaceous, 

 thinly pubescent and green above, softly pubescent but piloso- 

 pubescent on main nerves and paler (glaucous in recent) beneath, 

 3-9 cm. long, 2^-8 cm. broad ; main nerves 7 and radiate ; 

 veinlets rather densely reticulated ; petiole shorter than the 

 blade, narrow, retrorso- patently pubescent, li-9cm. long. 

 Panicles axillary, solitary or sometimes geminate, aphyllose or 

 very rarely 1-leafy at the base, shorter than the leaves, narrow, 

 1—6 cm. long, very shortly peduncled, with fasciculately race- 

 mose short branches, which bear 2 to several pedicellate flowers ; 

 rachis and branches adpressed-pubescent, viridescent in recent ; 

 bracts minute, ovato-rhombic, abruptly acuminate, shortly
