286 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. Feanus.

Herb. Kew.—Native names; '*Gouri-bet? (Nepal), “Rue” or “Rhu” (Lepchas). 
OBSERVATIONS.—This seems very variable in size and in the armature of the sheaths 
and spathes. I have described the male plant from a large Sikkim specimen kindly. 
sent to me by Lieut.-Colonel Prain, and consisting of the upper portion of an entire 
plant, with the leaves forming a large crown as in some species of Pinanga; the 
sheaths are 5 cm. in diam. and are all without flagella, every one bearing a spadix. 
This specimen was certainly not scandent. The sheaths are covered with small 
tubercles ; the petiole is 2 cm. in width, and the entire leaf measures 1'5 m. in 
length end the spadices more than 3 metres; the spathes are almost unarmed. The 
fruiting specimens of the Calcutta Herbarium have the sheaths armed with better 
conformed spines, of which some have straight acicular points ; the spathes also are 
much more densely prickly than in the Sikkim specimen mentioned above. ©. montanus 
T. And., of which I have seen the fruit in the Herbarium at Kew, seems to me 
exactly the same species as (C. acanthospathus. 
The adult plant seems devoid of leaf-sheath flagella, but these may be present in 
its juvenile period. | 
The chief characteristics of C. acanthospathus are its non-scandent suberect habit; 
the short tubercled spinous leaf-sheaths; the large leaves with large  many.eostate 
and plicate lanceolate inequidistant remote leaflets, which are always solitary and never 
paired on each side of the rachis; the very long spadices, the female inflorescences 
with subscorpioid spikelets where the flowers are in two collateral series and some- 
what nnilateral; the fruit with scales of an uniform cinnamon-brown colour, subshin- 
ing and channelled along the middle.—Allied to the following. 
Prate 105.—Calamus acanthospathus Grif. Upper portion of a leaf-sheath with 
the base of a spadix; lower portion of a spadix with mature fruit; terminal portion 
of & female spadix with ovaries in course of development; two leaflets as seen 
from the lower surface; one leaflet from the upper surface; two seeds, one showing 
the back and the other the raphal side; one seed longitudinally cut through the 
embryo.—(All figures from a specimen in the Calcutta Herb.).

Description.—Scandent, of moderate size. Sheathed stem 16-22 cm. in diam. ; 
canes 1 cm. thick, with rather short internodes.  Leaf-sheaths cylindraceous, rather 
thick and almost woody, distinctly marbled with dark-green and lighter furfuraceous 
spots, rather powerfully armed with solitary and scattered stout subdimidiate-conic 
spines, which are broad at the base, where further they are rather swollen above 
and flat or slightly convex beneath, horizontal or deflexed, 6-12 mm. long, leaving 
an elongate triangular impression above them and accompanied by very short and 
tuberculiform prickles. Ocrea very short, truncate, entire, glabrous, spinulous. Leaf. 
sheath flagella very long, callous at their insertion, flattened and with prickly very 
acute edges in their lower portion, irregularly armed upwards with solitary or 2-3
