BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 81 
ternate, usually deflexed spines, the centre ones often longer than the side ones. Leaflets 
numerous, narrowly lanceolate, 15~30 cm. long, 1-1°5 cm. broad, very distinctly fascicled 
and usually, at least in the intermediate part of the leaf, pointing in different ways, 
often many of those near the apex subequidistant. Male spadiz simply decompound 
or rudimentarily supra-decompound, the spikelets bearing at each spathel a glomerule of 
flowers or very short and subscorpioid secondary spikelets which are composed of 
4-8 flowers. Female spadix about 2 m. long, including a terminal flagellum; spikelets 
slender. Fruiting perianth explanate. Fruit pisiform, 8-9 mm. in diam. Seales in 15 
series, channelled along the middle, 
Java. 
C. viminalis var, fasciculatus (Roxb.) Bece.—.Leaffeis distinctly fascicled and all 
pointing different ways, except a very few of the apical. 
C. viminalis var. fasciculatus sub-var. bengalensis Becc.—Fruit slightly turbinate, 
8 mm. in diam, Scales in 16-18 series. 
Bengal and Burma, 
C. viminalis var. fasciculatus sub-var. pinangianus Becc.—More robust than 
sub-var. bengalensis. -Male spikelets as much as 20 cm. long, with distinct secondary 
spikelets bearing 2 series of as many as 8 flowers each. 
Pulo Penang, 
C. viminalis var. fasciculatus sub-var. andamanicus Becc.—Robust. Leaf-sheaths 
slightly armed. Fruit sphercial, 8:5-9 mm. in diam. Scales in 20 series. 
Andamans, 
45, C. siamensis Becc.—Sheathed stem 17 mm. in diam. Leaf-sheaths armed with 
laminar elongate spines. Leaves with a very short petiole; rachis armed beneath with 
straight and hooked spines. Leaflets more than forty on each side, very closely 
set in one plane and equidistant, narrowly lanceolate, unicostate, the intermediate 
ones 15-16 em. long, 12-13 mm. broad. Female spadiz elongate (as in C. fasciculatus) 
the largest spikelets 8-9 cm. long, with about 30 spathes. Female flowers numerous, 
very closely set and very conspicuously 4-seriate, two flowers equally developed and 
fertile issuing from each spathel, with a sterile flower between the two. Very 
similar in other respects to 0. fasciculatus. 
46. C. concinnus Mart.—Scandent, of moderate size. Leaf-rachs armed beneath 
with rather long, straight, deflexed spines. Leaflets numerous, distinctly fascicled, 
ensiform or lanceolate-ensiform, unicostate, with 3-4 rather distinct secondary nerves 
on each side of the mid-costa. Male spadiz ultra-supra-decompound; primary spathes 
elongate-tubular; secondary  spathes infundibuliform, subscarious, loosely sheathing. 
Fruiting perianth explanate. Female spadix simply decompound; spikelets 8-12 em. 
long, with 18-20 distichous flowers on each side. Fruits small, globose, 8-9 mm. ia 
diam. Scales in 18 series, deeply channelled along the middle.
