succulent, laxly leaved and glabrescent below, towards the apex 
densely leaved and pubescent. Leaves long-stalked, membranous, 
polymorphic often on the same specimen, cuneate and entire below, 
rarely obtuse, sometimes ovate-elliptic or oblong-elliptic and acuminate 
with a weakly toothed margin, sometimes obovate or obcuneate 
and more or less deeply cut towards the apex or 3- to several-lobed ; 
lobes unequal, erect or spreading, narrow triangular, acuminate, 
4-6 in. long, 14-3 in. wide, with a few scattered adpressed hairs on 
the upper face, paler and hirtellous along the nerves beneath ; 
lateral nerves 6—7 on each side, rather prominent beneath, ascending ; 
petiole slender, sparsely pubescent, 2 in. long in the lower leaves, 
becoming shorter above. Stipules small, narrowly lanceolate or 
linear-acuminate, 1-14 lin. long, pubescent, subpersistent. In-

late, green, scarcely fleshy, to 1} in. long, passing above into a long 
erect linear tapering appendage, 24-33 in. long, which is slightly 
dilated at the apex, base shortly prolonged beyond the stalk and 
passing into a short upwardly curving appendage, 4 in. long or 
less ; peduncle 1-2 in. long. Male flowers 1-androus, limb of the 
very thin perianth shortly and irregularly 3-4-dentate or almost 
obsolete ; female flowers fewer, inserted in a row on either side of
