nervisque pilosis, subtus pilosis et minute leviter aculeatis, 
margine apiculato-dentatis ; inflorescentiis terminalibus, elonga- 
tis, circiter 20 cm longis, dense subadpresse pilosis; sepalis 
oblongo-ovatis ad ovato-lanceolatis, circiter 6 mm longis, petalis

A scandent shrub, the branches terete, brown, more or less 
pilose, and with small, reflexed, scattered aculei 1 mm long or 
less. Leaves simple, thickly coriaceous, olivaceous, ovate to 
oblong-ovate, 6 to 12 cm long, 3 to 7 cm wide, shining, apex 
sharply acuminate, base broadly truncate-rounded and distinctly 
cordate, prominently 5- or 7-nerved, the nerves straight, the 
primary ones all ascending, 5 to 7 on each side of the midrib, 
the primary reticulations subparallel, prominent, the margins 
acuminate-dentate, the upper surface glabrous or pilose on the 
midrib and lateral nerves, the lower surface pilose on the midrib 
and nerves and also with few scattered, minute aculei ; petioles 
pilose, minutely aculeate, 1 to 1.5 cm long; stipules narrowly 
oblong, free or nearly so, deciduous, about 4 mm long. Panicles 
terminal, narrow, up to 20 cm long, pilose, the younger parts very 
densely so, slightly aculeate, the lower branches 3 cm long or 
less, spreading, widely scattered. Flowers about 1.8 cm in dia- 
meter, their pedicels 10 mm long or less. Sepals oblong-ovate 
to ovate-lanceolate, somewhat acuminate, externally densely 
pilose with pale appressed hairs, internally densely cinereous- 
puberulent. Petals thin, glabrous, caducous, narrowly oblong- 
obovate, about 4 mm long, glabrous, base narrowed, apex
