 covered with short hairs, ultimately with a few scattered stinging

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, shortly 

 stalked, wedge-shaped, with a short acumen at the apex, base bluntly 

 rounded or almost truncate, margin denticulate, shallowly undulate, 

 base 3-nerved, with 3-4 additional ascending lateral nerves on each 

 side, nerves conspicuous beneath, as are also the horizontal trans- 

 verse connecting veins, 6-7 in. lon<^, 3J-4J in. wide, upper face 

 glabrescent, puberulous only on the nerves, lower face sparsely pubes- 

 cent, cystoliths not visible ; petiole stout, J 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 

 irregularly 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 

 almost to the base into 4 obovate-oblong segments, ciliolate on the
