(1) P. longifolium Roxh. Hort. Beng. 280; Trin. Sp. Gram. 
Ic. 138. 
Fairly robust grass, about 2 ft. tall. Leaves linear, long 
acuminate, i ft. long, -15 in. wide, edge minutely denticulate. 
Sheaths rather narrow, mouth of sheath with a few long white 
bristles. Panicle above the highest fully developed leaf, 8 in. 
long with 4 to 6 distant purple racemes, with white bristles at 
the base from the sheath below. Racemes 1-5 in. long, flattened; 
rachis narrow, -i in. wide, edges white-hairy. Spikelets in 4 rows, 
elliptic-orbicular, purple or green, glabrous or nearly so, with a 
strong central nerve and one intramarginal obscure on each edge 
of the outer glume. Stigmas plumose, purple. Open country, 
Singapore (Cuming, Hullett); Holland Road (Burkill). Selangor, 
Kwala Lumpur; South Salak Road (Seimund). Perak, Thaiping 
(Wray). Penang (Curtis). Distrih. India. 
(2) P. platycoleum Ridl. 
A robust plant. Leaves quite glabrous, narrow linear acuminate, 
with a long point about 8 in. long, •! in. wide at base, sheaths very 
broad, lower ones nearly i in. wide when spread open and 475 in. 
long. Peduncle slender, spikes 5 to 8, narrow, rachis linear, -i in. 
wide, edges hairy. Spikelets in 4 rows, small, hairy, *04 in. long, 
elliptic, narrowed at both ends, outer glumes hairy, central nerve 
very inconspicuous, intramarginal obscure. Stigmas purple, 
plumose. Hab. Damp spots, Selangor, Port Swettenham (Burkill 
4509). Distrih. Siam, Bangson, wet paddy fields (Haniff). Java 
(Zollinger 192 in Herb. Kew). 
Steudel bases his P. cognatuni {Syn. Glum, 28, No. 172) ou ^ specimen 
from Java (Zollinger 192), but his description does not agree in the least 
with the specimen under that number in Herb. Kew; thus he describes the 
spikelets as glabrous, whereas in this plant they are unusually hairy. The 
very broad leaf-sheaths and stout culm and small hairy spikelets are character¬ 
istic of this plant. 
(3) P. orbiculare Forst. fd. Prod. 7. 
A tufted plant, about 2 ft. tall. Leaves linear, rather stiff, 
edge entire acuminate, quite glabrous, 8 to 12 in. long, *15 in. 
wide. Panicle slender, of 2 to 4 racemes, 2-25 to 3 in. long, edge 
of narrow rachis quite smooth. Spikelets in 2 rows, pale, sub- 
orbicular ; nerves i central and 2 faint intramarginal ones. Stigmas 
brown. Hab. Common in open country and along roadsides, 
Singapore, Tanglin; Tana Merah Besar and Holland Road (Bur¬ 
kill). Malacca (Griffith). Negri Sembilan, Bukit Tangga Pass. 
Selangor, Kwala Lumpur. Penang, Waterfall Gardens (Burkill). 
Tringganu (Yapp). Distrih. Indo-Malaya, Australia, Polynesia. 
Native names for this and preceding species : Rumput Tulong 
Sentadok; Rumput Hijau; Rumput Patah Siku. 
This species is less robust than P. platycoleum and with fewer spikelets 
on the raceme.
