lous. Leaves ovate or rotund-ovate, abruptly acuminate, base blunt, 
truncate or subcordate, margin crenulate but generally entire near the 
base, with 3 to 5 ascending lateral nerves on each side above the 3- 
nerved base, connecting veins numerous, subparallel, conspicuous on 
the lower face, 23-63 in. long, 14-5 in. wide, upper face glabrous, and 
when dry closely dotted with cystoliths, lower face glabrate or sparsely 
puberulous or shortly hairy on the midrib and nerves, cystoliths 
shortly linear ; petiole shorter than the leaf. United stipules broadly 
triangular-lanceolate, shortly hairy on the edges and nerves, soon

longer than the petiole, rather laxly flowered, the short peduncle and 
spreading branches puberulous, flowers stalked, pedicel about 1 lin.
