252 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. pygmous. 
HaBrrar.— Borneo in Sarawak: on the hills near the sea at Bintulu, Beccars P. B. 
No. 3698, 
OBSERVATIONS.—The species is founded on a specimen of an entire leaf and a 
female spadix in flower. Its affinities are not obvious. It would appear to approach 
C. bacularis, and like this I suppose it an erect and not a climbing species on account 
of its non-cirriferous leaf and the form of the leaf-sheaths which are not gibbous, 
not tubular but widely open on the ventral side and gradually passing into the 
petiole. Provisionally I have placed it amongst the anomalous species of Group IV. 
Prate 85,—Calamus myriacanthus Becc’ —Leaf-sheath; an intermediate portion of a 
leaf (lower surface); the summit of the same leaf; basilar portion of a male spadix 
with an entire partial inflorescence.—From Beccari, P, B. No. 3698. 
70. Catamus pyomaus Bece. Malesia, iii, 62, and Rec. Bot. Surv. Ind. ii, 205. 
Description.—Not scandent, very small and delicate. Stem very short, torulose, 
creeping and rooting, 7-8 mm. in diam., its internodes excessively short and 
covered by the remains of the old leaves, the summit ascending.  Leaf-sheaths not 
flagelliferous, not or very shortly tubular at the base, amplectent and open on 
the ventral side, gradually passing into the petiole, armed with flat, small, 4-7 
mm. long, deflexed tawny spines, which are very often approximate by their bases 
and  subseriate. Ocrea short,  liguliform, at first fringed-furfuraceous at the 
margins, ultimately naked and deciduous. Leaves not cirriferous, 45-50 cm, in 
length, including the rather long (16-18 cm.) petiole; this subterete but narrowly 
channelled above, armed, mainly near the base and beneath, along the middle, with 
few, straight, horizontal, 5-6 mm, long spines; rachis quite unarmed, covered when 
. young with brown, fugacious, woolly-furfuraceous indumentum, rounded beneath, 
acutely bifaced above; leaflets numerous (20-30 on each side), very closely and 
regularly equidistant or pectinately set, mostly opposite near the base, alternate 
upwards, inserted at an angle of 45°, thin in texture but rigidulous, brownish and 
dull when dry, concolorous on both surfaces, linear-lanceolate, slightly narrowed at 
the base, gradually acuminate into a rather densely  setose ciliate apex; the mid- 
costa (rather strong) and one secondary nerve on each side of it spinulous above; 
beneath, the mid-costa alone sparingly spinulous; all leaflets of about one size, the 
largest 10-12 cm. in length and 6-8 mm.~ wide, only few near the base and 
those near the summit slightly smaller; the two of the terminal pair quite free at 
the base. Male spadiz filiform, very long and delicate, with very few (2) partial 
inflorescences of which the lowest supradecompound, the uppermost simply decom- 
pound; primary and secondary spathes and spikelets as in the female spadix here- 
after described;  spathels tubular as in the female spikelets; involucre cupular 
laterally attached to the base of the spathel above its own, acutely bidentate on 
the side next the axis. Male flowers very small, hardly 2 mm. long; calyx strongly 
veined, divided down to the middle into 3 broad acute lobes; corolla with acute 
segments, twice as long as the calyx. Female spadiz, relatively to the size“ of the 
plant, excessively long (1-L8 m.), filiform, terete, very slender, 2 mm. in diam. at
