28. C. radulosus Becc.—WSheathed stem 2:5-3 cm. in diam. Leaf-sheaths densely- 
armed with obliquely inserted, ascending, triangular spines. Leaves rather large, 
1:2-1°5 m. long; petiole none. Leaflets numerous, equidistant, 2-3 em. apart, ensiform, 
the intermediate ones 45 mm. long, 25 mm. broad, 3-costulate, the 3 cost bristly 
beneath towards the apex, on the upper surface orly the mid-costa sometimes bristly; 
the upper leaflets gradually smaller, those of the terminal pair 13-15 cm. long, 
8-12 mm. broad, shortly connate at the base. Male spadiz ultra-decompound. Female 
spadiz simple decompound, very long, with many, remote, very long, partial inflorescences; 
primary spathes elongate; lower spikelets 8-9 cm. long with 20-23 flowers on each 
side: secondary spathes, spathels and involucres strongly scabrid. Fruiting perianth 
explanate. Fruit small. 
The Malayan Peninsula. 
29. C. rugosus Becc.—Scandent, slender. Sheathed stem 8-10 mm. in diam. 
Leaf-sheaths srmed with short triangular horizontal confluent subvertical laminar spines 
and with spinulous wrinkles interposed between the whorls of the larger spines. 
Leaves about 70 cm. long; the petiole elongate. Leaflets numerous equidistant, closely 
set, linear or linear-lanceolate, unicostate, 15-17 cm. long, 8-10 mm. broad, on the 
upper surface the  mid-costa and one nerve on each side of it rather densely 
bristly, underneath only the mid-costa bristly; the terminal pair of leaflets slightly 
smaller than the others, free at the base, Female spadiz filiform, with few very 
small partial inflorescences; these with few and short spikelets; secondary spathes 
and spathels scabrid. ; 
The Malayan Peninsula. 
3). C. flabellatus Becc.—Scandent, very slender. Sheathed stem 5-6 mm. in 
diam.  Leaf-sheaths striate, unarmed. Leaves simple, elongate-flabelliform, furcate or 
parted into two broadly lanceolate, acuminate, acutely 6-7 -costate lobes, green on 
both surfaces. :
