273 LEAFLETS OF PHILIPPINE BoTANY [Vou. I. Arr. 16 
1.5 cm. in diameter, the upper one half free and conical, 
irregularly 5 to 7-angled but the edges more rounded and 
converging toward the truncate greenish apex; stigmas plane, 
sessile, approximate, 7 to 11, brown, 0.75 mm. in diameter; 
fertile seeds 7 or more to each drupe. 
Type specimen 9083, A. D. E. Elmer, Mount Banahao 
near Lucban, Province of Tayabas, Luzon, January,1907. This 
singular species has been observed here and there as isolated 
trees in well drained soil of light woods and in dense 
thickets skirting the mountain at 650 meters. Section Vin-

GRAMINEAE, 
Gigantochloa merrilliana n. sp.—Slender trees forming 
large clusters; stems smooth, green, often appearing glaucous, 
about 15 cm. thick; branches terete, numerously rebranched, 
half drooping, very hard and tough. Leaves disticbously 
arranged along the ultimate twigs, chiefly descending and 
recurved upon the very short contracted base, slightly paler 
green beneath or even glaucous, more or less conduplicate 
on the upper surface, 2 to 3 dm. long, 2 to 4 cm. wide, 
gradually tapering toward the sharply acuminate apex, base 
abruptly contracted into a very stout flattened petiole, ovately 
linear or linearly oblong, about 2 cm. apart, smooth, or 
only slightly scaberulous, glabrous; the lateral veins obscure, 
the straw colored midvein quite prominent beneath; leaf 
sheath smooth, closely fitting the stem and overlapping, 
well separated toward the apex, glabrous, truncate; mature: 
stem sheaths not observed, but those on the twigs 3 cm. 
long, glabrous, acuminate, involute, terminated by a 6 mm. 
long setaceously pointed subdeflexed foliaceous bract; ligule 
also glabrous, of a rigid axillary membrane 2 mm. wide 
through the middle and extending from tip to tip of the 
sheath apices; nodes thickened, ring like. Inflorescence upon 
special subaxillary slenderly drooping branches usually below 
the leafy twigs, from 3 to 9 dm. long; these branches are 
sparingly rebranched and are subtended at the base by 
many short imbricated tough bracts forming a sort of tube, 
spikelet bearing from the base, the internodes 1 to 2 cm. 
long; spikelets 3 to 5-clustered, each cluster alternatingly
