PHILIPPINE URTICACEAE. 515 
the base varying from 7 to 35 mm, the lowest tooth of the broader side 
often projecting beyond the general outline so that the leaf appears lobed, 
the teeth usually extremely shortly acuminate, the apex never projecting 
beyond the general outline of the leaf, but contracted at each of the apical 
2 or 3 teeth when these are present, in entire leaves gradually tapering, 
minutely apiculate, except for this the terminal tooth varying in shape 
from narrowly lanceolate to semicircular; sometimes definitely tripli- 
nerved, but the nerves, especially on narrower leaves except the lobed ones, 
little longer than the succeeding veins, the arched connections forming 
a distinct lateral vein; both surfaces with fairly long cystoliths: stipules 
lanceolate, acute, 2.5 to 4 mm long, deciduous. 
Luzon, District of Bontoe, Bauco, in forests at 1650 m elevation, Vanoverbergh 
828. The specific name is descriptive, even for Hlatostema, it being difficult to 
characterize the leaves in words that would not include half the species of the 
genus. Staminate receptacles have not yet been collected, but it is very probable 
that the alliance is with the species with which it is here placed, having peduncled 
receptacles with corniculate bracts.

River* (Infanta), Bur. Sci. 9323 Robinson, the former pistillate, the latter a 
slightly more delicate plant with staminate flowers also, 
Very distinct from any other described Philippine species, but it is probably 
the closest alliance of Bur. Sct. 9195 Robinson, from Mount Malulud, Polillo,
