458 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (C. unifarius 
squarrose or not very adpressed, in 15 series, Shining, straw-coloured, not distinctly 
channelled along the middle, sometimes slightly depressed towards the point, this 
somewhat elongate, reddish-brown; margins erosely toothed. Seed irregularly globular 
7 mm. long, deeply and coarsely pitted on the back, with a deep narrow chalazal 
fovea on the raphal side; albumen subruminate or with superficial intrusions of 
the integument; embryo basal. 
Hasitat.—Java. The specimens distributed by Zollinger with No. 2305 (Herb. 
Boiss. and  Delessert) were gathered on the Mount Semiru between 300-1,000 m. 
above the level of the sea. In the De Candolle Herbarium one specimen with im- 
mature fruit bears the No. 2302. In the Herbarium at Bruxelles another Zoliinger’s 
specimen with a male spadix bears the No. 1595 and was collected in the Botanic 
Garden at Buitenzorg.—Javan name ‘‘Bandil.” ^ Some specimens sent to the St. 
Petersburg Herbarium by Teysmann (and probably cultivated) are labelled ‘“ Rotang 
Tertas”; and others that I have received from Dr. Treub (cultivated) are named 
* Hoè Karok rok.” One specimen of a leaf with its sheath, collected by Dr. 
Warburg in Sumbawa (Herb, Berol) at 1,300 m., apparently belongs to 0. unifarius. 
OBSERVATIONS.— Distinguished in the group by the sheaths armed with scattered 
acicular bulbous spines; cirriferous leaves with remote subequidistant rather large 
lanceolate many-costulate leaflets; male spikelets slender; the involucre explanate 
subtending and not enveloping its flower; fruiting perianth small pedicelliform; fruit 
globose 1 cm. in diam.; scales subsquarrose not channelled along the middle; seed 
globular, coarsely pitted; embryo basal.—The affinities are with €. pisicarpus, aruensis 
and Hollrungii. | 
Prate 206.—Calamus unifarius, H, Wendi.—Leaflets (under-surface) with portion 
of the rachis—from Zollinger’s No. 2305 in Herb. Boiss.; portion of a male spadix 
in flower with an entire partial inflorescence,—írom a specimen in St. Petersburg 
Herb.; portion of a spadix with immature íruit,-—írom Zollinger’s No. 2302 in Herb. 
DeCand.; portion of a spadix with immature fruit; seeds, one in two halves cut 
through the embryo,—from Zollinger’s No. 2305 in Herb. De Cand. 
CALAMUS UNIFARIUS var. Penrone Becc. in Hook. f. Fl. Brit. Ind, vi, 458 and 
in Rec. Bot. Surv. Ind. ii, 212. 
DESCRIPTION. —Female spadiz terminating in a rather elongate flagelliform appen- 
dix. Involucrophorum more or less distinctly pedicellate, very conspicuously callous at 
its axilla.—Other characters as in the type. 
Hasirat.—The Nicobar Islands, from where Mr. E. H. Man forwarded to me a 
specimen of a female spadix with immature fruit under the native name of ‘ Pentong.” 
Another specimen of this variety is in the Calcutta Herbarium and was collected at 
Kamorta, also in the Nicobars, by Kurz in February 1875. 
OssEkvAiIONS.— Man's specimen of the fruit-spadix is accompanied by a non-cirri- 
ferous (radical?) leaf; the naked canes are 16-17 mm. in diam. with internodes about 
25 cm. long, The surface is vitreous straw-yellow. The involucrophorum is very dis- 
tinetly pedicellate in the basal portion of the female spikelets where also the involucre is
