In the general alliance of P. urinaria Linn, coming closest to P. benguetensis, 
but distinguished from it- by the much smaller and differently shaped leaves. 
The largest-leaved specimens get close to P. greenei Elmer, but even in this 
comparison the branchlets of the latter are thicker, and more definitely angled, 
and glabrous, and the leaves are of slightly different shape. 
Local names (Ifugao) : uguggip, giwi-giwi. 
Phyllanthus macgregorii sp. nov. § Eriococcus. 
Frutex : floribus pistilliferis longiter pedicellatis, fasciculatis ; perian- 
tliio 6-partito, segmentis ovatis vel ovalibus, integris ; disco subintegro ; 
ovario triloculare, glabro ; stylis alte bifidis, reclinatis: foliis lanceolatis 
vel ellipticis, basi obtusis, apice breviter acuminatis. 
Pistillate flowers in axillary fascicles ; peduncles slender, dilated at the 
apex, glabrous, 17 to 32 mm long, arising from crowded, very small, ovate, 
pubescent bracts : calyx 1.7 to 2 mm long divided for about two- thirds of 
the distance to the base into 6, entire, glabrous, oval or ovate, acuminate 
segments ; disk nearly flat, thin, on vertical view slightly undulate ; ovary 
depressed-globose, about 1.3 mm in diameter, glabrous, 3-celled ; styles 
3, forked almost or quite to the base, the arms reclining on the ovary, 
about 0.7 mm long: capsule seen up to about 5 mm in diameter, similar 
to the ovary, the seeds not fully developed, their testa smooth. 
Probably a shrub, the branches terete, slightly ridged, the branchlets 
somewhat compressed, pilose along two opposite lines, the older shoots 
progressively glabrescent ; bark dark-reddish, tending to grayish-brown 
on the older shoots : petioles -1 to 2 mm long ; lamina membranaceous or 
slightly thicker, lanceolate, elliptic, or oblong-lanceolate, 3.5 to 6 cm long, 
1.5 to 2.5 cm wide, nearly equilateral, the base obtuse, the apex contracted 
into an acute or subacute, mucronulate acumen, about 2 to 3 mm long, 
or merely subacute, upper surface yellowish- or somewhat brownish-green, 
the under slightly paler, both glabrous; pairs of veins 10 to 15, slender, 
often little more conspicuous than the intermediates, uniting at their 
extremities to form an arched submarginal vein; stipules lanceolate- 
acicular, less than 1 mm long, caducous. 
Babuyanes Islands, Dalupiri, Bur. Sci. 10128 McGregor. Two or three 
other species of Phyllanthus have been left undescribed, owing to the lack of 
one or the other kind of flowers, but P. macgregorii appears to be so closely 
allied to P. stipularis Merr. that its section may be predicted without the 
staminate flowers. From that species, it may be distinguished by the much 
smaller stipules, and the less oblique leaves with much more crowded veins, and 
of different outline and more uniform color on the two surfaces. In general 
appearance, P. macgregorii has even greater similarity to P. gracilipes Muell.-Arg. 
than to P. stipularis, but the calyx-segments of P. gracilipes are not entire, nor 
is the ovary glabrous : it also is in the section Eriococcus.
