long; rachis narrow flat. Spikelets small, solitary or paired, 
stalked, lanceolate or oblong, glabrous or minutely pubescent. 
Glume I 3- to 5-nerved, lanceolate; glume II 5-nerved; glume III 
smooth. Hab. Roadsides and waste ground and seashores, very 
common and variable, whole Peninsula. Distrib. All countries 
warm enough for it. 
The chief varieties occurring here are : — 
A. var. commuiaiwn Hook. fil. l.c. 15. A tall stout, nearly 
glabrous form with rather large leaves. Racemes many, 3 to 
6 in. long, crowded, and sometimes whorled. Spikelets rather 
broad, sub-glabrous. Hab. Singapore (Hullett). 
B. var. ciliare Hook. fil. l.c. 15, A tall slender form with 2 to 
6 slender racemes; rachis narrowly winged. Glumes I and II 
strongly ciliate on the edges. Hab. Malacca Hill (Ridley). 
C. var. pntriens Hook. fil. l.c. Rhizome short creeping, often 
forming close tufts of stems. Leaves usually short, edge thickened 
often undulate sub-globose; sheaths white hairy. Racemes 3 to 
13 together, 3 to 6 in. long. Spikelets not ciliate, lanceolate acute 
narrow. Glume I nearly as long as glume II, which is very narrow 
and 3-nerved. Hab. Waste ground and seashores, the seashore 
form condensed and tufted; our commonest form. Singapore, 
Tanglin; Tanjong Katong. Malacca (Griffith, Cuming, Murton). 
Selangor, Salak South (Seimund); Damansara Road, Kwala Lum¬ 
pur; Batu Caves (Ridley). 
D. var. debile Hook. fil. l.c. A dwarf plant 6 to 12 in. tall, 
slender, tufted. Leaves short, -5 to 1 in. long. Racemes 2 or 3, 
slender, i*5 to 3-5 in. long; rachis narrowly winged. Spikelets 
lanceolate acuminate, very narrow, glabrous. Hab. Sandy and 
poor soils, Singapore and Malacca. 
(2) D. pertenuis Buse in Miq. PI. Jungh. 381. 
Very slender creeping ascending grass, creeping stems i ft. 
long, ascending part 9 to 12 in. long. Leaves thin lanceolate- 
linear acuminate, 3 in. long, -12 in. wide, sparsely white hairy or 
glabrous. Racemes 3, very slender, 3 in. long, quite glabrous. 
Spikelets lanceolate, narrow, -12 in. long. Hab. V^aste ground.

ix. 469. Paspalum longiflorum Retz. Obs. iv. 15; Hook. fil. F.B.l. 
vii. 17 (in part); Ridl. Mat. iii. 126. 
A small creeping ascending species, creeping part of stem about 
8 in. long, ascending culms 7 to 12 in. tall. Leaves lanceolate 
acuminate, rather stiff, glabrous, -6 in. long, -i in. wide. Racemes 
2 or 3, slender, 1-25 to 2 in. long; rachis very narrow, slightly 
winged. Spikelets elliptic-oblong, whitish from their appressed 
pubescence. Glume I absent or mere trace of it; glume 11 broad 
oblong, nearly as long as the spikelet. Grain ellipsoid, white.
