194 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (C. interruptus 
CALAMUS FLORIBUNDUS var. DEPAUPERATUS Bece, 
Description.—Small, delicate, 1 m. high (O. B. Clarke). Sheathed stem very 
slender, 5-6 mm. in diam, Leaf-sheaths armed with very small, short and broad 
spines. Ocrea densely  bristly-hispid. Leaves 35-40 em. long with 6-8 leaflets (in 
al) in two groups; leaflets 15-20 cm. long, 15-22 mm, broad; those of the 
terminal pair more or less connate at the base; petiole and rachis armed with small 
scattered claws. Male spadiz slender, flagelliform, almost simply decompound, with 
2-3 small partial inflorescences. 
Hasrrat.—Gari at 400 m. in the Garo Hills in Assam, C. B. Clarke in H. 
Beccari. 
OxseRVATIONS.—This variety at first sight appears very distinct from the 
type, and recalls some of the forms of C. javensis. 
Piare 48.—Calamus floribundus var. depauperatus Becc, C. B. Clarke’s entire 
specimen in H. Becc. 
38. CALAMUS INTERRUPTUS Becc. Malesia iii, $0 and Ree, Bot, Surv. Ind. ii, 204. 
Descrietion.—Scandent, of moderate ize. Steathed stem 15-20 mm. in diam. 
Leaf-sheaths cylindrical, almost glaucescent, fugaciously furfuraceous, slightly gibbous 
above, very obliquely truncate at the mouth, gradually passing into the petiole, armed 
with a few strong, scattered, solitary or sometimes confluent, deflexed, flattened 
and straight and subulate 15-20 mm. long spines, which have a broad base 
concave. beneath. Ocrea small, glabrous, liguliform and membranous, narrowly 
bordering the margins of the base of the petiole and the mouth of the sheath. 
Leaf-sheath flagella very long and robust, flattened and acutely two-edged in their 
lower portion where they are spinulose-serrulate or furnished with small aseendent 
prick'es at the sides, terete above and strongly armed with scattered or aggregate 
or hulf-whorled claws. eaves not cirriferous, 1:5 m. long; the petiole rather long 
(25-35 em.) very broad at the base, where deeply channelled above and with 
acute membranous naked margins, rounded and unarmed beneath in its first 
portion; higher up flat and smooth above, and armed irregularly beneath along 
the middle and at the sides, like the first portion of the rachis, with rather 
robust and scattered claws; the rachis bifaced and smooth above, and armed rather 
densely beneath, mainly in the upper portion, with sirong, solitary, or more or 
less confluent, black-tipped claws; the ieaflets not numerous, about 15 on each 
side, irregularly approximate into 4-5 distant fascicles of 2-3 on each side, 
elongate-lanceolate, gradually narrowed to an acute base, acuminate at the apex 
into a subulate, naked or very sparingly bristly tip, 25-35 cm. long, 2°5-3 
em, broad,  papyraceous, rather firm, brown when dry, shining above of the 
same colour on both surfaces, perfectly glabrous, their mid-costa acute ew and 
with 2-3 secondary nerves on each side of it, naked on both surfaces: jaan 
veinlets sharp, much interrupted, margins acute, smooth; the two ieadlidà of the 
terminal pair somewhat shorter than the others and confluent by their bases.— 
Other parts unknown. The leaves acquire a dark brown colour on drying.
