DecemsBer 15, 1910] URTICACEAE FROM THE VICINITY OF Mr. Apo 881 
comparatively thin, coriaceous, turning sordid brown in the 
dry state, glabrous, elliptic or elliptic oblong, entire toward 
the obtuse base, otherwise regularly serrately dentate, the 
normal blades 17 cm. long by 7 em. wide across the 
middle, the basal one half more tapering, densely covered 
on both sides with minute cystoliths; midvein prominent 
and dull straw brown beneath especially so below the middle, 
with a pair of lateral veins arising near but not at the base 
which extend 1 cm. within the margin clear into the 
abrupt apical point; cross bars quite conspicuous and alternat- 
ing with minor ones, at right angles, curved, al) glabrous; 
petioles stout, smooth and glabrous, 5 cm. long; stipule 
glabrous, short and intrapetiolar, on the sides bluntly dentate. 
Infloreseence and infrutescence axillary, cymosely branched 
from near the base, at most 5 cm. long in the fruiting 
state; branches compressed when dry, glabrous, rather de- 
licate and slender; pistillate flowers in small glomerules, 
sessile or stout pedicellate; perianth lateral, glabrous, 3-lobed, 
the keel-shaped middle one 1.25 mm. long, rather thick 
and with a blunt apex, the sharply pointed -lateral ones 
less than one half as long; achene lenticular, 1 mm. across, 
with a fine row of glands on the sides along the edges, 
subtended at the base by 3 glands; stigma minutely papil- 
late, upon a short and rather thick neck; staminate buds 
compressed, globose, 1.25 mm. thick, glabrous, minutely 
apiculate, parting into 4 segments; stamens as many as there 
are segments; anther broadly elliptic, inflexed in the bud, 
deeply bilobed, nearly 1 mm. long; the flattened filaments 
glabrous. 
Type specimens 10487 pistillate and 11758 staminate, 
A. D. E. Elmer, Todaya (Mt. Apo), District of Davao, Min- 
danao, May and September respectively, 1909. 
Collected the pistillate number in rich moist soil of 
humid forests at 8750 feet along the Baruring river. The 
staminate specimens were gathered at the junction of Colon 
creek with the Baruring at a higher elevation, forming dense 
clumps about clear thermal springs or pools on sandstone 
basins. The former is called ''Buas," the latter ‘‘Salimbagun’’ 
by the Bagobos. Dedicated to Dr. C. B. Robinson who has 
materially aided me in the preparation of this article.
