34. P. leucocalyx, Wutchinson in Kew Bulletin, 1911, 316. Stems 
slender, woody, terete or nearly so, glabrous; flower-bearing branchlets 
slender and elongated, up to 6 in. long, terete, glabrous. Leaves oblong 
or oblong-elliptic, conspicuously mucronate, obtuse and slightly rounded 
at the base, 3-4 lin. long, 1-1? lin. broad, rather thin, with recurved 
margins, glabrous on both surtaces; lateral nerves 5-6 on each side, 
distinct below, invisible above ; petiole very short; stipules subulate- 
filiform, about 1 lin. long, persistent. Flowers moneecious, about 3 
males in the axil of each of the lower leaves, females solitary in the 
upper half of the branchlets; pedicel short, glabrous, those of the 
female stouter than those of the male. Male flowers: Sepals 5, obovate- 
elliptic, with 1 broad median nerve, glabrous. Disk-glands 5, large, 
flat and conspicuously warted. Stamens 3; filaments connate into a 
slender column; anthers free among themselves. Female sepals larger 
than those of the male, penninerved, obovate-elliptic, 14 lin. long, i lin. 
broad, glabrous. Disk thin, crenate, glabrous. Ovary globose, con- 
spicuously warted ; styles erect, rather long, slender, bilobed ; stigmas 
globose. Capsule 1} lin. in diam., conspicuously warted in the upper 
half. Seeds very closely marked on the back with about 14 fine long!- 
tudinal lines.—P. rotwndifolius, var. lewcocalyx, Miill. Arg. in DC.Prodr.

Easily distinguished from P. rotundifolius, Klein ex Willd., by the long slender 
styles, globose stigmas, and warted ovary. 
35. P. microdendron, Welw. ex Will. Arg. in Journ. Bot. 1864, 330. 
Habit somewhat like that of a little tree (Welwitsch); stem woody; 
terete in the lower part, flattened and grooved, when young ; flowering 
branchlets subterete, up to 3 in. long. Leaves ovate-elliptic or oblong- 
elliptic, acute or subacute, sometimes with a very sharp point, mostly 
rounded and slightly unequal-sided at the base, 3-8 lin. long, 13-3 lin. 
broad, rather rigidly membranous, slightly scabrous on both surfaces ; 
lateral nerves 6-7 on each side, distinct ; petiole } lin. long; stipules 
subulate from a slightly broadened base, nearly 1 lin. long, glabrous. 
Flowers moneecious, males small, geminate in the axils of the eRe 
leaves of each branchlet, females larger and solitary in the upper leaves.
