very difficult to distinguish in the juvenile stage. Griffith also very likely speaks of 
young plants of C. latifolius when he writes:—“ There were also specimens found 
among the dried plants of the Botanic Garden without names, but which are said to 
have been prepared from plants growing a long time ago in the Gardens; these, had 
the petioles (rachis Becc.) been flagelliferous, I should have referred to C, Jatifolius”; 
Palms Brit. India, p. 67 under C. floribundus. Furthermore in the large work of 
Griffith in the observations on €. latifolius, we read:—''I have a personal knowledge 
of this species", whereas in the Calcutta journal the same phrase is written:—“I 
have no personal knowledge, etc."; this last version being doubtless the correct one, 
as the description and the plate of C. latifolius in Griffith’s work are from Roxburgh; 
moreover in the same lines in the Calcutta journal the author adds :—“ It (C. latifolius) 
appears to be allied to the succeeding species;” viz. C. palustris, and this is perfectly 
correct, while in the illustrated large work the succeeding species are C. insignis first, 
then comes C. geminiflorus and lastly C. palustris. It clearly follows from the above 
that Griffith made the comparison between €. latifolius and C, palustris, as the place 
of C. insignis has been changed and C. geminiforus added by the publisher of the 
posthumous edition. As to C. macracanthus T. And., I have no reason to doubt its 
identity with C. latifolius. 
Prare 176.—Calamus latifolius Hoz5. Portion of the sheathed stem with hase of 
a leaf and lower portion of a female spadix; very young detached fruits belonging 
to the above-mentioned specimen.—From a specimen collected in Sikkim and forwarded 
to me in 1902 by Lt.-Col. D. Prain. 
CALAMUS LATIFOLIUS var. MARMORATUS Becc. 
DescriPTioN.—High scandent, more slender than the type. Sheathed stem 2 cm, in 
diam.; naked canes 1 em. thick with a polished surface and internodes 15-20 em. 
long. Leaf-sheaths of the younger shoots marbled with alternating mealy white and 
= dark green transverse bands, more or less armed as in the type with broad solitary 
or subverticillate spines and furthermore in the intervals with much smaller tri- 
angular spines, which have a broad base and are at first adpressed and erect and 
afterwards horizontal and disposed in transverse unequal interrupted undulate series. 
Leaves smaller than in the type and with fewer pairs of leaflets, these also smaller, 
the largest 25-28 cm. long, 6 cm. broad, but exactly of the same shape, conspic- 
uously concayo-convex, usually oblong or oblanceolate, distinctly geminate on each 
side, with one or more broad longitudinal shining bands on the upper surface; 
petiole with a few erect spinules on its upper surface. Male spadiz simply decom- 
pound, similar to the female one of the type, but with more densely spinous primary 
spathes; spikelets comparatively broad, about 3 cm. long, with 8-12 flowers on each 
side; spathels very closely packed, bracteiform, concave, sometimes with a denticulate 
margin and prolonged at one side into a triangular acute point, which projects 
beyond the involucre and subtends the flower; involucre dimidiately cupular, deep, 
acutely bidentate, sharply two-keeled and deeply excavate on the side next to the 
axis, Male flowers oyate, 5 mm. long; the calyx finely striately veined, divided 
about midway down into 3 broad acute lobes; the corolla one-third longer than the 
calyx.
