PHILIPPINE URTICACEAE, II.

subobtuse, of the wider side obtuse or slightly auriculate, the margin of 
the wider side with usually 7 or 8 teeth, of the narrower usually with one 
or two less, the >apex protracted but hardly exceeding the general outline ; 
triplinerved, other veins usually 4 or 5 on each side, but they and especially 
the minor reticulations usually little conspicuous ; glabrous, but the upper- 
surface with numerous cystoliths ; stipules subulate, 2 to 3 mm long. 
Luzon, Subprovince of Benguet, Baguio and vicinity, in ravines, Merrill 761/3 
(type), Bur. Sci. 11975, ty004 Robinson ; Mount Tonglon, on banks along trail 
at 1,600 to 1,800 m, Phil. PI. 811 Merrill; Sablan, Bur. Sci. 12752 F6nix. The 
last specimen was formerly referred by me 9 to E. viridescens Elmer, to which 
E. lutescens has great general similarity both in field and herbarium, but on 
comparison of a very large quantity of material, it differs very constantly in all 
the characters above noted. Its real alliance is with E. angustatum C. B. Rob., 
which is a more delicate and usually much less branched plant, with thinner 
(when dry) leaves, the margins with more numerous teeth, and the apex more 
prolonged. 
17a. Elatostema merrillii sp. nov. 
Admodum parvum, basi reptans, altius ascendens: receptaculis ses- 
silibus, staminiferorum bracteis bre.viter sed inaequaliter comiculatis ; 
floribus pentameris : f oliis parvis, oblique oblanceolatis vel obovatis, tri- 
plinerviis vel saepius admodum quadxuplinerviis. 
Staminate receptacles sessile, few-flowered; outer pair of bracts oval, 
2.5 mm long, one of them with a spur extending about 1 mm beyond 
the general outline, spur of the other shorter and much less conspicuous, 
both long-ciliate on the margins and back ; next two pairs of bracts cune- 
ate-oval, 2 mm long, ciliate ; bracteoles oblanceolate, 2 mm long ; pedicels 
short ; perianth-segments 5, oval or oblong, 1.5 mm long, slightly cornic- 
ulate, sometimes ciliate at the apex; filaments about 1.5 mm long; 
anthers 0.6 mm long, the cells widely separated at the base: pistillate 
receptacles sessile ; outer and inner bracts more or less similar, ovate to 
lanceolate, shortly corniculate, 2 mm long, ciliate on the margins, more 
or less villose on the back ; bracteoles narrowly oblanceolate, nearly 2 mm 
long, ciliate; pedicels very short; perianth-lobes 3, rounded, less, than 0.1 
mm long; achenes light-brown, about 0.5 mm long. 
Plants creeping at the base, thereafter ascending, the stems 10 to 30 
cm long, densely covered at the apex with rather soft whitish or yellowish 
somewhat spreading soft pubescence, less densely so below : leaves sessile, 
the membranaceous lamina obliquely oblanceolate or obovate, 14 to 26 
mm long, 6 to 12 mm wide, or some especially toward the base of the 
plant smaller, the narrower side acute at the base, the wider rounded or 
slightly auricled, the margin of the wider side not deeply cut into 10 to 12 
teeth, the narrower side with about half the number and entire toward 
the base, the teeth more often ciliate at the apex, apical tooth merely
