Wile Land. British East Africa: Mbuyuni, Scott Elliot, 6200! 
Very nearly allied to the West African 7’. angolensis, Mill. Arg., but ee 
larger, with a woody branching stem ; most readily distinguished by the smaller male 
bracts and the longer male pedicels. Also nearly allied to 7. ukambensis, Pax, 
which, however, is densely armed with stinging hairs, and has much longer racemes

slender, several from a woody rootstock, erect or suberect, 8 in. to 1} tt. 
high or occasionally more or less twining above then 2-24 ft. long, very 
sparingly branched, puberulous or glabrescent, without stinging hairs. 
Leaves short-petioled or subsessile, firmly membranous, lanceolate 0
