718 CXXII, EUPHORBIACE& (HUTCHINSON). _ [ Phyllanthus. 
37. P. Paxii, Hutchinson in Kew Bulletin, 1911, 316. A small 
shrub; stems erect, very slender, woody, terete, glabrous; flowering 
branchlets distant, up to 4} in. long, very slender, terete, glabrous, 
Leaves lanceolate or elliptic-lanceolate, narrowed to both ends, sharply 
mucronate at the apex, 2-6 lin. long, 1-2 lin. broad, thinly chartaceous, 
glabrous on both surfaces; lateral nerves about 11 on each side, con- 
spicuous on the lower surface; petiole } lin. long, slightly fleshy ; 
stipules subulate, a little Jonger than the petiole. Flowers monecious, 
axillary, females solitary in about two or three leaf-axils towards 
the ends of the branchlets, males geminate, occupying the lower part 
of the branchlets; male pedicel slender, short, female stout and 
thickened towards the top, about 2 lin. long, glabrous. Male flowers: 
Sepals 5, oblong-elliptic, obtuse, 3 lin. long, faintly 1-nerved, margins 
membranous. Disk-glands 5, small, conspicuously warted. Stamens 3; 
filaments connate their full length; anthers slightly connate, cells 
parallel, dehiscing longitudinally. Female flowers: Sepals 5, ovate, 
obtuse, 1} lin. long, } lin. broad, slightly coriaceous, glabrous, with mem- 
branous entire margins. Disk saucer-shaped or cupular, thin, margin 
crenulate. Ovary rather deeply lobed, smooth ; styles slightly divergent, 
rather deeply bifid; stigmas not swollen. Ripe capsule not seen.

A small shrub; flowering branchlets produced singly, angular or very 
slightly winged, glabrous. Leaves elliptic, rounded to a minute point, 
rounded at the base, 3-4 lin. long, 13-2} lin. broad, green, very thin, 
glabrous on both surfaces; lateral nerves about 3 on each side, faint 
below, invisible above, margins slightly recurved; petiole } lin. long, 
glabrous; stipules ovate-triangular, acute, 3-3 lin. long, membranous, 
brown, glabrous. Flowers monecious. Male flowers: Sepals 5-6, 
obovate, rounded at the apex, about 3 lin. long, glabrous. Disk-glands 
5-6, rounded, smooth. Stamens 2-3; filaments connate to the top ; 
anthers dehiscing at the side. Female fluwers: Sepals oblong-ellipsoid, 
rounded at the apex, 1} lin. long, 3 lin. broad, with membranous 
margins, glabrous. Disk flat, entire or slightly undulately lobed, 
glabrous. Ovary subglobose, 6-lobed, glabrous; styles erect, bilobed 
to below the middle, lubes not swollen at the tips. Capsule about 
1} lin. in diam. Seeds trigonous, convex on the back, 1 lin. long, with 
about 7 lines on the back.—P. rotundifolius, var. leucocalyx, Baker

Since Mr. Moore ¢escribed this species I have associated with it several other 
specimens which appear to me to be the same. They show variation in the number 
of sepals (5-6) and stamens (2-3), a variation which appears to occur but rarely in 
the genus, so far as I can judge after dissecting numerous examples of many of the 
species,
