€. palustris var. amplissmus Bece.—Very robust.  Sheathed stem 45 em. in diam. 
-Leaves as much as 3:5 m. long in the pinniferous part. Leaflets subequidistant, only 
occasionally approximate in pairs on each side of the rachis, very large, up to 
50 cm, long and 8-10 cm. broad. 
Native country uncertain, 
C. palustris var. malaccensis Becc.—Sheathed stem 25-3 em. in diam. Leaflets. 
not very numerous, very inequidistant, 2-3 approximate—often with a solitary one 
and a long vacant space interposed—on each side of the rachis, 5-7-costulate, 
lanceolate, the largest — 39 cm. long, 3-4 em. broad; spikelets more slender than 
in the type. 
The Malayan Peninsula. : 
C. palustris var. cochinchinensis Becc.—Smaller than the type.  Sheathed stem 
about 2:5 em. in diam. Leaflets in distant pairs on each side of the rachis, with 
long vacant spaces interposed, narrowly lanceolate, 15-35 cm. long, 4-5 cm. broad. 
Fruit broadly ovoid.ellipsoid, 15 mm. long, 9 mm, broad.

147. C. latifolius Roxb.—Seandent. Sheathed stem about 3 cm. in diam. Leaf- 
sheaths armed with very large aud broad, laminar, sub-regularly verticillate spines. 
Leaves 2-25 m. long in the pinniferous part. Leaflets not numerous, almost 
herbaceous in texture, very inequidistant, rather regularly geminate on each side of 
the rachis, strongly concavo-convex, broadly lanceolate or elliptic-lanceolate, 30-35 em. 
long, 6-8 cm. broad, usually with 5-7 costz, these smooth on both surfaces. Other- 
wise very similar to the typical form of O. palustris. 
N, E. India. 
C. latifolius var. marmoratus Bece.—More slender than the type. Leaf-sheaths 
about 2 cm. in diam., marbled with mealy and dark green spots and armed with 
verticillate broad-based and smaller interposed spines. eaves smaller, with fewer 
pairs of leaflets; these 25-28 em. long and 6 cm. broad at most. 
N. E. India. 
148. C. spinifolius Becc.—Seandent, rather slender.  Leaf-sheaths 1-2 cm. in 
diam., sparingly prickly. Leaves of the upper part of the plant  cirriferous, 50-65 
em. long in the pinniferous part; petiole short or 8-10 cm. long. Leaflets not 
very numerous, distinctly geminate or ternate on each side of the rachis, rigid 
papyraceous, elliptic or lanceolate-elliptic, 10-15 em. long, 20-25 mm. broad, acumi- 
nate, 3-5-costulate, the mid-costa usually furnished on the upper surface at least 
with one, more frequently several, relatively strong and short erect spines, smooth 
underneath, occasionally smooth on both surfaces; margins remotely spinulous. 
Lower leaves paripinnate, the leaflets 3-4 cm. broad, and with several slender, 5-7 mm. 
long spines on 3-5 costz above. Male spadiz donde; elongate, simply decompound ; 
spikelets 15-20 mm. long with very closely packed flowers. Female spadiz shorter 
than the leaves, diffuse, with few partial inflorescences; spikelets 5-6 cm. long with 
7-8 flowers on each side, zig-zag sinous. between the flowers. Fruiting perianth 
almost explanate. Fruit spheric, beaked, 1 cm. in diam. Scales in 18 series,
