PHILIPPINE URTICACEAE.

another except at the base; next two pairs oblong-obovate, nearly as long 
as the outer, keeled, not ot barely corniculate, ciliate-serrate ; bracteoles 
oblanceolate, 3.5 mm long, ciliate or ciliolate; flowers shortly pedicelled; 
perianth-segments 4, ovate, 1.5 mm long, with long, ciliate spurs; anthers 
0.7 mm long: pistillate receptacles still young; as seen -the outer pair 
of bracts about 2 mm long, orbicular-ovate or wider than long, pilose, one 
or both slightly corniculate ; the next pairs narrowly oblanceolate ; flowers 
apparently typical, the stigma long-pilose. 
Erect except at base, about 20 to 25 cm high, the stems densely pubes- 
cent at the apex and often lower: leaves sessile, the lamina membrana- 
ceous, obliquely obovate or elliptic-obovate, 3 to 6.5 cm long, 12 to 28 mm 
wide, the base inequilateral, acute or subobtuse on one side, obtuse or 
subauriculate on the other, the narrower side usually with 2 or 3 teeth, 
the wider with 4 or 5, the apical tooth forming an acumen over 1 cm 
long or on younger leaves much shorter and hardly projecting beyond 
the general outline; tri-triplinerved, the nerve of the narrower side 
sometimes little longer than the 2 or 3 veins ; the glabrous upper surface 
with conspicuous cystoliths, the under pubescent on the veins with much 
less conspicuous cystoliths ; stipules narrowly oblong-lanceolate, acute, 
3 to 4 mm long.

general appearance to E. lusonense, but differing by its sessile receptacles and 
otherwise. 
24. Elatostema scriptum sp. nov. 
Erectum, succulentum, caulibus tetragonis, plus minusve alatis, gla- 
bris : receptaeulis staminiferis breviter pedunculatis, bracteis exterioribus 
interioribusque orbieularibus vel late ovatis, corniculatis ; floribus tetra- 
meris : foliis membranaceis, subfalcatis, oblique et saepe anguste lan- 
ceolatis vel ellipticis, margine dentatis, apice acuminatim protractis, 
subpinnatinerviis. 
Dioecious, as far as known : staminate receptacles on sparingly pilose 
or glabrous peduncles 1 to 3 mm long; outer bracts free except at the 
base, orbicular or broadly ovate, on the largest receptacles about 9 mm 
long, rounded at the apex, distinctly corniculate, somewhat pilose on the 
outer surface or glabrous, the spur ciliate ; inner bracts similar, somewhat 
smaller ; flowers shortly pedicellate, perianth-segments 4, hyaline, 1 mm 
long, with a ciliate spur of nearly equal length. 
Erect, succulent, the glabrous stems 20 to 30 cm long, quadrangular 
and more or less winged (very imperfectly shown by dried material), 
simple or more rarely branched : leaves sessile, the lamina membrana- 
ceous, obliquely and often narrowly -lanceolate or elliptic, more often, 
subfalcate, 7 to 13 cm long, 1.2 to 3 cm wide, the upper usually the 
longer, base of the upper side acute, of the lower acute or very shortly
