10. U. cuneata, Rendle in Journ. Bot. 1916, 370. Stem stout, 
terete, sparsely armed with simple slender columnar protuberances 
bearing short stinging hairs, and also hispidulous. Leaves large,shorily 
stalked, wedge-shaped, with a short acumen at the apex, base bluntly 
rounded or almost truncate, margin denticulate, shallowly undulate,

glabrescent, puberulous only on the nerves, lower face sparsely pubes- 
cent, cystoliths not visible; petiole stout, } in. long, armed with 
protuberances similar to those on the stem. Inflorescence (young 
female) axillary, to almost 2 in. long, consisting of a stout axis densely 
covered with stinging hairs some of which are borne on simple or 
regularly branched often flattened protuberances, also puberulous, 
with a few spreading main branches; flowers borne in close uni- 
lateral cymes on the short ultimate branchlets. Perianth divided
