PHILIPPINE URTICACEAE. 533 
especially on the narrower side more strongly directed toward the apex. It is 
possible that two species are here included, differing from one another in the 
coarseness of the dentation and the pubescence, but it will take field-study to 
determine this with certainty. This is probably the closest of all the Philippine 
species to true H. sessile Forst. 
Through the kindness of Dr. A. B. Rendle, of the British Museum of Natural 
History, a photograph has been obtained of the type specimen of &, sessile Forst., 
preserved in the herbarium of that institution, No one of our species is identical 
with it, HZ. carinoi, its nearest ally, differing by the distinetly longer leaf-acumen. 
(Plate II, Vol. VI.) 
Local name (Baguio): ngaluy, the plants said to serve as food for deer. 
29. Elatostema angustatum sp. nov. 
Receptaculis sessilibus vel subsessilibus, solitariis vel binis, staminif- 
erorum bracteis exterioribus tricarinatis admodum corniculatis; floribus 
tetrameris: foliis membranaceis, oblique anguste lanceolatis vel rarius 
ovatis, basis valde inaequilaterae uno latere acutis altero subacutis ad 
rotundatis, margine dentatis, apice attenuato-acutissimis. 
Monoecious or dioecious, the receptacles solitary or paired, sometimes 
one of each kind in an axil: staminate receptacles 3 to 4 mm in diameter, 
the outer pair of bracts free from one another except at their bases, 
broadly oval or suborbicular, 3.5 mm long, slightly ciliate, the back 
with usually 3 very distinct keels more or less projecting apically, the 
next pairs of bracts obovate, cucullate, corniculate, 8 mm long ; bracteoles 
nearly hyaline, oblanceolate, cucullate, 2 mm long; perianth-segments 
4, hyaline, ovate, 1 mm long, very shortly or not cucullate: pistillate 
receptacles up to 1 em in diameter; bracts fused in the basal half, the 
outer pair triangular-ovate, 1.5 mm long, slightly ciliate, keeled-cornicu- 
late, the others similar but narrower; bracteoles linear-oblanceolate, 2 
mm long, ciliate-serrate; flowers shortly pedicelled; perianth-lobes 3, 
minute; achenes 0.6 mm long. 
Erect, sueculent, 20 to 40 em high, glabrous except as noted for the 
inflorescence: leaves subsessile, the lamina membranaceous, oblique, nar- 
rowly lanceolate or on short leaves wider, 3 to 16 cm long, 7 to 18 mm 
wide, the base acute on one side, subacute to rounded on the other, the 
narrower with from 6 to 14 shallow teeth usually confined to the apical 
three-fifths or half, the wider with from 6 to 20 and the lowest more 
basal, the apex very gradually narrowed to a very acute or rarely obtuse 
point or on shorter and broader leaves acuminate : triplinerved, the point 
of origin of the nerve of the narrower side often from 8 to 20 mm from 
the stem, the nerves on both sides forming a continuous and nearly straight 
lateral line united with the costa by 3 to 9 veins; cystoliths conspicuous 
on both surfaces ; stipules linear-lanceolate, 1.5 to 2.5 mm long.

Province of Laguna, Los Bajios, Bur. Sci. 6614 Robinson, As suggested to me 
by Dr. Gagnepain, the species has considerable resemblance to EH. hookerianwim 
Wedd., but differs in its much more. attenuate leaves with less auriculate bases 
and more numerous serrations, in the cystoliths and the stipules.
