846 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (ÇC. symphysipus. 
unarmed, very finely striately. veined, fugaciously scaly-furfuraceous, almost horizontally 
truncate and naked at the mouth, slightly prolonged at one side into a short acute 
point; the lower branchlets, the largest, 8-9 cm, long, somewhat arched-patent or 
even deflexed, inserted above the mouth of their own spathes, with 6-7 spikelets on 
each side and prolonged at the summit into a simple slender, filiform spikelet, this 
longer than the side ones; tertiary spathes similar to the secondary ones but smaller 
and more horizontally truncate; spikelets very slender, filiform, inserted above the mouth 
of their own spathe with a small axillary callus, the lower ones the largest, 2:5 cm. 
long with 12-14 flowers irregularly arranged in two series and not flatly bifarious; 
the upper ones speedily smaller; the extreme with a flower alone; spathels tubular-in- 
fundibuliform, strongly striately veined, truncate and entire at the mouth, apiculate 
at one side; involucre slightly prominent but not pedicellate, laterally attached 
outside its own spathel at the base of the one above, with a distinct waxy callus 
at the axilla next to the axis, discoid with a narrow  scale-like margin. Male 
flowers’ irregularly ovate-oblong, usually somewhat narrowed to the base, often 
asymmetric and obsoletely angular by mutual pressure, obtuse, 4 mm. long; the 
calyx short, obconic-campanulate, membranous, strongly  striately veined, with 3 
broadly triangular acute teeth; the corolla 3 times and even more as long as the 
calyx, divided into 3 oblong, obtuse or apiculate, strongly striately veined segments, 
Female spadix and fruit unknown. 
Hasirat.—The S. W. coast of New Guinea, Zippel, according to Blume. | 
OssERVATIONS.—l have seen only one incomplete specimen, apparently the one 
figured by Blume, of this highly characteristic but imperfectly known species not 
found again hy modern botanists. The description above of the leaf-sheath and ocrea 
is from Blume as I have not seen these parts. The male flowers by their small 
calyx and asymmetric long corolla call to mind those of some Arecinee, and the 
leaflets elongate-spathulate, cochleariform, green, sharply and closely transversally 
veined on both surfaces and very approximate -in- couples on each side of the rachis, 
distinguish this Calamus from the allied species; probably it approaches C, Cumingianus 
more than any other species. 
Prate 140.—Calamus heteracanthus Zipp. An intermediate portion of a leaf 
portion of the male spadix with au entire partial inflorescence; two detached branchlets 
with male flowers.—From the authentic specimen in the Leyden Herb.

Description.—Scandent, rather robust. Sheathed stem probably 3-4 cm. in diam 
Leaf-sheaths armed with few not very large spines in a small portion from near 
the base of the petiole which I have seen. Leaves probably about 2 metr. long, 
mot eirriferous, or terminating in much reduced leaflets and  subeirriferous ; petiole 
rather robust, about 15 cm. long, 13 mm. thick, almost’ flat or broadly and super- 
ficially channelled above, round and smooth’ beneath, armed et the sides with
