C. Guruba.) BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 299 
The specimens which I now eonsider as the young stage or as a form of C 
paspalanthus and which received the name of D. intumescens were gathered by Father 
Scortechini in the State of Perak. I have seen two other Specimens very similar 
to these, sent from Johore to the Berlin Herbarium by H. N. Ridley. Scortechini’s 
specimens have a sheathed stem 10-12 mm. in diam.; the leaf.sheaths are very 
conspicuously puffed up or inflated-tumescent at the base of the petiole, are almost 
black, opaque, very finely scabridulous (when dry), sparsely armed with scattered 
1-2 cm. long spines; the ocrea is speedily marcescent and vanishing, not fibrous; 
the leaves with the petiole are armed at the margins near the base with horizontal 
rather close very slender spines; the leaflets are exactly as in the type but smaller, 
15-16 cm. long, 8-9 mm. broad.

of a leaf (under surface); male spadix. From No. 577 in the Calcutta Herb.

Description.—Scandent, slender or of moderate size, Sheathed stem 1-2 cm. 
in diam. Leaf-sheaths gibbous above, armed with light-brown scattered, solitary, 
flat, elastic, narrowly triangular-lanceolate and subulate spines which are commonly 
8-12, but sometimes even 20 mm. long, usually ascendent and obliquely inserted, but 
occasionally horizontal and less frequently even deflexed, their base broad, concave 
beneath and decurrent at the sides; amongst these are intermingled many other spines 
of the same shape but much smaller and sometimes very minute. Ocrea in young 
leaves large, 6-7 cm. long, unarmed, speedily lacerate and deciduous, brown, papyra- 
ceous, glabrous, exsuccous, Leaf-sheath flagella slender, prickly throughout even in 
their lower portion. Leaves not cirriferous, 60-80 cm., and in very vigorous. plants 
up to 1'3 m. in length; petiole (of the upper part of the adult plant) 12-20 cm. 
long, flat or slightly channelled above, where usually smooth, but sometimes very. 
sparingly spinulous near the base (occasionally on each side of it near the mouth
