PHILIPPINE URTICACEAE. 
493 
angled and annulate, the internodes swollen, about 1 to 1.5 cm long: 
petioles of leaves of a pair distinctly of unequal length, the lamina less 
conspicuously unequal, the petioles flattened, 1 to 5 cm long, the lamina 
lanceolate or elliptic-lanceolate,' 7 to 12 cm long, 1.8 to 3 cm wide, the 
base acute, the margins shallowly serrate except for a varying distance 
from the base, gradually contracted from below or about the middle to a 
slender apex or barely acuminate or falcate, membranaceous, both surfaces 
most thickly crowded with cystoliths, the under’ thereby glaucous, trip- 
linerved or almost trinerved, the veins connecting the midrib with the 
basal nerves usually very obscure, but on other leaves of the same plant 
well evident, the inferior anastomoses very inconspicuous ; stipules broadly 
triangular, 1.5 mm long, more or less persistent. 
Mindanao, Lake Lanao, Camp Keithley, Mrs, Clemens 1223. A very distinct 
species,, but of uncertain relationship, owing to the lack of pistillate flowers. 
11. Pilea calcicola sp. nov. 
Sueculenta, tota glabra, caespitosa: monoica, inflorescentiis brevibus: 
petiolis inaequalibus, pro rata longiusculis, lamina membranacea, tripli- 
nervia, ovata vel late ovata, dentata, acuminata; stipulis parvis. 
Monoecious; the inflorescences solitary, more often paired, rarely in 
threes, slightly exceeding 1 cm in length or shorter, their peduncles up 
to 4 mm in length or flowered to the base, pinnately branching, the flower- 
bearing branches more or less fascicled, both staminate and pistillate 
flowers borne distichously on articulated pedicels which are slightly 
elongated after anthesis and then about 1 mm long: perianth-segments 
of staminate flowers 4, oblong-lanceolate, acuminate; filaments flattened, 
dilated toward the base, about 1 mm long, anthers white, suborbicular, 
cordate and obcordate, about 0.5 mm in diameter; rudiment of ovary 
minute: lobes of pistillate perianth 3, unequal, the intermediate 0.75 
mm long, oblong, cucullate, minutely apiculate, the laterals oval to lan- 
ceolate, 0.4 mm long, acuminate; staminodes small; ovary compressed, 
somewhat obliquely oval or ovate, 0.7 mm long; stigma vely small, sub- 
terminal, penicillate; achene light-brown, strongly tuberculate especially 
in the submarginal area. 
A succulent, densely cespitose planf, the internodes of variable length 
from 3 to 22 mm and about 3 mm in diameter at the base, glabrous 
■throughout : petioles varying in length from 5 to 28 mm, those of leaves 
of a pair distinctly unequal, the lamina less definitely unequal, ovate or 
broadly ovate, not succulent, membranaceous when dry, 14 to 30 mm 
long, 11.5 to 17 mm -wide, the base emarginate, rounded or greatly 
narrowed, the margins with usually 8 teeth, which are somewhat blunt 
■and at least often glandular, apex acuminate,. the smaller leaves rarely 
almost entire; triplinerved, the nerves continuing for one-half to more 
than two-thirds the length of the . lamina, with 5 or 6 slender transverse
