936 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (C. Reinwardtii 
‘broad and swollen base and leave above: them a distinct impression on the sheath. 
Ocrea indistinct or probably deciduous. ZLeaf-sheath flagella slender, filiform, smooth 
and flattened in their basal portion, aculeolate upwards. eaves rather large, 1-5 mm. 
long; petiole rather long (30 em.) broadly channelled above, remotely aculeolate at the 
‘margins, round and smooth beneath; rachis rounded beneath, where in its lower portion 
clawed at the sides, and almost unarmed along the . middle, which is furnished with 
rather crowded solitary claws in its upper third part; above the rachis is broadly 
bifaced. with its upper angle formed by two fine, raised, parallel, very approximate 
lines which originate from the mid-costa of every leaflet decurring along the centre 
of the rachis; leaflets patent, numerous, equidistant, very closely set, alternate or almost 
opposite, papyraceous, rigidulous, green, concolorous and shining on both surfaces, 
narrow-linear, very slightly narrowed and suddenly plicate at the base, not very 
gradually acuminate at the summit into a filamentose apex, with a mid-costa very 
acute above and slender beneath, but minutely and closely spinulous on both surfaces, 
and one slender nerve (on each side of it) remotely bristly above and naked beneath; 
all leaflets about the same size, 15-16 em. long and 8-10 mm. broad, only a few near 
the summit shorter; the two of the terminal pair the smallest, free at the base; 
transverse veinlets very fine, much interrupted ; margins very finely and closely spinu- 
lous-serrate.— Other parts unknown. :

OBsERVATIONS.— This seems allied to C. zebrinus. It is distinct in the group by its 
subclavate sparingly spinous leaf-sheaths; by the leaves with a long petiole, which is 
smooth beneath; by the very numerous equidistant linear leaflets which have con- 
spicuously finely and closely spinulous-serrate margins and the mid-costa finely spinu- 
lous on both surfaces and one slender nerve on each side of it; this is bristly above 
and naked beneath.
