The plant referred to by Engler (Glied. Veg. Usambara, 51) under the 
name Urera obovata, Benth., as climbing on high trees is perhaps this species ; 
Scheffler’s specimen no. 196 cited above was distributed under this name.

teeth blunt, with 3 lateral ascending nerves on each side above the 
3-nerved base, 3-4 in. long, 13-24 in. wide, upper face rough with
