C. nambariensis. | BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 435 
~ 
one-half as long; spathels very closely packed, imbricate, bracteiform, concave, broadly 
ovate, finely striately veined, scaly-ciliolate at the margin, prolonged into a point which 
subtends the base of the flower and after the fall of this projects beyond the involucre; 
this dimidiately cupular, acutely bidentate, two-keeled and deeply excavate on the 
side next to the axis, the keels very sharp and ciliolate. Male flowers small, 3 mm. 
long, rather obtuse or apiculate; the calyx with a short, veined tube, its teeth as 
long as the tube, broad at the base and with an acuminate point; the corolla 
about twice as long as the calyx, the segments finely longitudinally striate.

OssERVATIONS.— This seems very nearly allied to ©. inermis, but the leaflets 
though very similar in every respect to the shape of this, are equidistant and not 
approximate in pairs. It seems also related to some forms of C. palustris, from 
which however it also differs in the regularity of the distribution of its leaflets. 
The armature of the leaf-sheaths reminds us much of that of ©. latifolius var. 
marmoratus, but in C. nambartensis the secondary spines are ascendant, 
To the kindness of Mr. G. Mann I am also indebted for another specimen 
of a fruit-spadix without leaves of a Calamus collected also on the Khasia Hills and 
forwarded to me with the same number (4) as the male specimens described above, - 
This spadix, which bears quite mature fruit, is about 1 metre in length, less 
diffuse than that of C. khasianus, spreading, arched, with 7 partial inflorescences and 
terminating in a taillike strongly aculeate, 8 cm. long appendix; the first 
very short acutely two-edged, 6 cm. long, with a few short prickles in its 
part; upper primary spathes 7-8 cm. long, narrowly tubuiar-infundibuliform, 
sheathing, armed in their upper part with rather strong and short claws; 
partial inflorescences attached at the mouth of their respective spathes more or less 
callous at their upper axilla, spreading, arched; the lower ones 35-40 cm. in length 
with 6-7 spikelets on each side; secondary spathes tubular-infundibuliform, about 
2 em. long, truncate and entire at the mouth with 1-2 small claws in their upper 
part; spikelets spreading, arched, attached just above the mouth of their own spathe 
with a distinct axillary callus, very similar to those of C. khastanus, but with 
shorter and more distinctly infundibuliform spathels, the larger ones 10-12 em. 
long, with about 10-12 flowers on each side, strongly zig-zag-sinuous; spathels 
infundibuliform, truncate at the mouth, very narrow at the base, where therefore 
axis of the spikelet is very slender at every bend; involucrophorum 
two-kecled and obsoletely bidentate on the 
spathe 
upper 
closely 
the 
cupular, truncate, almost entire, 
side next to the axis; involucre cupular, truncate, 
not or very obsoletely bidentate on the side of the neuter flower ; areola of 
the neuter flower lunate. Fruiting perianth shortly but very distinctly pedicelliform ; 
the calyx conspicuously constricted at the throat, depressedly subventricose. Fruit large, 
broadly ovate, almost equally rounded at both ends, very suddenly and distinctly 
mucronate, at the apex with a short caudiculum penetrating into the perianth, 30-32 
mm. long (including the caudiculum and the mucro) and 21-23 mm. in diam. ; scales 
cinnamon-brown, shining, in 21 series, deeply channelled along the middle with a dark 
piont and a very narrow intramarginal line; the margin erosely toothed. ^ Seed broadly 
subcrenulate at the margin;
