BAMBOOS OF THE PHILIPPINE ISLANDS. 
269 
Yar. striata Gamble in Ann. Bot. Gard. Calc. 7 (1896) 44. 
Luzon, Manila, Merrill 1050, sterile; cultivated for ornamental purposes, 
introduced from India or Malaya. 
I have never received flowering specimens of the variety striata, but the 
ordinary Bambusa vulgaris is frequently found in flower. 
3. Bambusa cornuta Munro in Trans. Linn. Soc. 26 (1868) 113. 
Bambusa corniculata Kurz in Ind. Forester 1 (1876) 341, non Munro. 
A straggling bamboo reaching a height of 7 to 8 m, the branches dilated and 
patellate at the nodes, reaching 1 cm in diameter. Leaves ovate-lanceolate, 
broadest and unequal at the base, rounded or more or less cuneate, apex long- 
acuminate, the acumen scabrid beneath, 30 to 35 cm long, 5 to 9 cm broad, the 
texture soft, thin; nerves 9 to 13 pairs; petiole very short, flat; sheaths striate, 
glabrous, truncate at the mouth and furnished on one or both sides with a stiff, 
straight, horn-like appendix about 7 mm in length, with a few, long, stiff bristles ; 
ligule short, truncate. Flowers apparently on separate flowering culms in very 
long, soft, branching panicles with many bracts, those on the upper branches 
scattered, those on the lower ones in heads. Spikelets oblong, acuminate, 5- or 
6-flowered, -the rachillas between the flowers glabrous, sinuate, 1 to 2 mm long; 
empty glumes 2, glabrous, acuminate, 3 to 5 mm long; flowering glumes 6 to 7 
mm long, mueronate, scabrous on the back; paleas as long as the fertile glumes, 
mucronate, tufted at the tip, stiffly villous between the keels; lodicules ovate- 
acuminate, not fringed. Stamens 6, free, linear, 2 to 3 mm long. Ovary cylindric. 
Stigmas 3, plumose. Fruit not known. 
Luzon, Province of Nueva Vizcaya, Quiangan, Merrill 124 '■> June 6, 1902. 
Known also from Java, Horsfield 193, Koorders 23693 (3 !, Bedalia Lake, Lamad- 
jong, Zollinger 4904 '■ 
I have felt a slight doubt about the identification of Mr. Merrill’s plant 
because the spikelets are not in rounded heads as they are in Koorders’ specimens. 
Zollinger’s specimens, however, show that lower verticils have the spikelets in 
heads while the upper ones have them scattered, so I conclude that the difference 
is merely one of position. The leaves of all the specimens agree excellently. 
I can not agree with Kurz in thinking- B. Horsfieldii Munro, 1. c. 115, to be the 
same as B. cornuta, after reading carefully the descriptions of the leaves. 
4. Bambusa M err i 1 1 i i Gamble sp. nov. 
Frutex arborescens, vagans. Culmi vagantes ad 18 m longi ; ramuli 
ad nodos culmi fasciculati, geniculati, infra nodos annnlos patelliformes 
ferentes. Folia lineari-lanceolata, apice in acumen setaceo-acuminatum

data, 8 ad 10 cm longa, 12 ad 15 mm lata; vaginae striatae, glabrae,

appendice corniformi erecto vel curvato sparse sed longe fimbriato in- 
structae ; ligula brevis truncata ; petiolus brevissimus complanatus. Flores 
in ramulis foliiferis, in capitulis congestis bracteatis 2 cm diametro 
aggregati; patella annularis sub nodis reflexa. Spiculae lanceolatae, 2.5 
ad 3 cm longae, dense hirsutae, flores 2 fertiles et ultimum sterilem 
ferentes; glumae steriles 2, mucronatae, dorso scabro-birsutae, nervis 
conspicuis, 7 ad 8 mm longae; glumae fertiles sterilibus similes, 10 mm
