408 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (C. latifolius. 
infundibuliform, narrowed a good deal to the base, faintly striately veined, entire, 
apiculate at one side, ciliolate-paleaceous at the mouth; involucrophorum enclosed 
into its own spathel and inserted at the base of that above, dimidiately cupular, 
rather deep, very acutely bidentate, two-keeled and deeply excavate on the side next 
to the axis, where not callous; involucre moulded on and immersed in the involucro- 
phorum with 2 projecting teeth (separated by a sinus) on the side of tke neuter 
flower, of which the areola is distinctly lunate and with sharply defined borders. 
Female flowers about 5 mm. long; the calyx finely striately veined, cut half-way 
down into 2 broad semi-ovate acute lobes; segments of the corolla as long as the 
calyx but narrower; filaments of the stamens united by their bases into a cup, 
triangular and black in the free portion. Fruiting perianth not distinctly pedicelli-

 HaBrrAT.—-lt ranges from Chittagong in Bengal to the sub-Himalayan hills of 
Sikkim, Nepal and Bootan ascending from the level of the sea to an elevation of 
about 700 metres. / 
Roxburgh has founded the species upon specimens gathered in Chittagong near 
the coast, where it has been found again at Seetakoond (Hooker f.) and at Paroha 
(Gambie). According to Anderson it grows in Sikkim near the stream Rayem in the 
Teesta valley at an altitude of 150 metres, about 4 miles from the plain; the same 
author adds that he has observed it (his C. macracanthus) in the valleys between the 
Teesta and Tchail in the first hills of Bootan. From Sikkim Lieut.-Col. Prain has 
forwarded me specimens (those I have described) with very young fruit, gathered 
on dry ground at Sivoke on the gentle outer slopes of the Himalaya. 
The native name in Chittagong assigned by Roxburgh is ‘‘Korak-Bhet.” Anderson 
gives the Lepcha names of ‘‘ Ruebee” and “ Greem,” and Gamble that of *'Phekori- 
Bhet.” Its rattan is very long, and when freed from the sheaths is about as thick 
as a slender walking cane. | 
OsBsERVATIONS,— C. latifolius is characterized by large leaves which are  cirriferous 
in the full-grown plant, with very concavo-convex 5-7-costulate, lanceolate leaflets, 
which are distinctly geminate on each side of the rachis with long vacant spaces 
interposed, and the large flat often subregular verticillate spines of its leaf-sheaths. 
_I think, however, that C. latifolius is distinguishable with great difficulty from C. 
palustris ; only the leaflets of the first seem more herbaceous in texture, more 
regularly geminate, more concavo-convex and not furnished with an axillary callus 
at their insertion and the spines are more distinctly confluent in whorls; other 
difference perhaps may be found in the fruit, which in C. latifolius is known only 
in a very young state. If the identity of the two mentioned species could be 
proved, the name of C. latifolius has the precedence as more ancient, 
The young plants of €, latifolius are erect and have not cirriferous leaves. In 
fact one leaf from a young plant of this species collected by Sir Dietrich Brandis at 
Sivoke on the Teesta terminates in a large bipartite leaflet. From this I am inclined 
io suppose that Roxburgh had assigned the name of C. humilis (also a native of 
Chittagong) to a young plant of C. latifolius er perhaps of C, inermis—two species
