PHILIPPINE URTICACEAE. 513 
datis, margine tertia inferiore parte excepta dentatis, apice breviter vel 
mediocriter acuminatis. 
Staminate receptacles on slender peduncles usually about 15 mm but 
up to 56 mm in length, the receptacles up to about 8 mm in diameter but 
usually smaller: outer pair of bracts semicircular, free from one another 
except at the base, distinctly corniculate, 3 to 4 mm long, glabrous or 
more or less short-pilose, the next pairs shorter and less corniculate, 
suborbicular; bracteoles linear-oblanceolate, pedicels varying with age, 
the flowers when fully mature exserted; perianth very deeply 4-parted, 
the segments ovate to lanceolate, about 2 mm long; filaments of equal 
length, the anthers about 1 mm long: pistillate receptacles sessile or on 
short peduncles, solitary, paired, or even fascicled, oblong to orbicular in 
outline, up to 8 mm in their greatest diameter, the outer bracts similar 
to those of the staminate but strongly fused with one another and the 
inner, being free only at the corniculate apex, inner lanceolate; bracteoles 
oblanceolate, ciliate; flowers shortly pedicelled; perianth about 0.1 mm 
long, with 3 rounded lobes; achene about 0.7 mm long, brown, longitud- 
inally striate; stigma penicillate. 
Erect, except at the base, the stems single or especially in somewhat 
drier situations tufted, simple or much less often branching, 10 to 50 
em high, glabrous but marked with cystoliths: leaves alternate or very 
rarely opposed by others greatly reduced, the dried lamina membrana- 
ceous, lanceolate to obovate, the size and probably somewhat the outline 
varying according to the habitat, the upper nearly always much larger 
than the lower, from 1 to 9 cm long, 7 to 33 wide, most often near 
the average of these figures, also with some still smaller, the base inequi- 
lateral, on the broader side rounded or subauriculate, on the narrower 
acute to subobtuse, the margins except in the basal third or less on the 
wider and farther on the narrower side somewhat coarsely dentate, the 
teeth from 6 to 9 on the wider and rather fewer on the narrower side, 
usually obtuse except the lowest, the terminal tooth from broadly ovate 
to narrowly lanceolate, continuing the general outline of the leaf or 
distinctly acuminate, usually obtuse, both surfaces often sparingly pilose, 
marked with cystoliths, triplinerved, with 3 to 5 additional veins, the 
finer reticulations usually very inconspicuous; stipules lanceolate to 
linear-lanceolate, 1.5 to 3 mm long.

The Malapadnabato collections, made in bulk, have greatly strengthened faith 
in the value of pedicelled staminate receptacles as a valid character, but indicate
