130 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (D. leptopus 
turned towards the side opposite to the spathes; they are straight, thickish and 
rigid; the lowest of each inflorescence is the largest, 5-8 cm. in length, and carries 
two collateral and unilateral series of 6-8 flowers each; as usual the upper spikelets 
are shorter and with fewer flowers; spathels obliquely infundibuliform, acutely angular, 
extended at one side into a triangular, dorsally keeled point; involucrophorum 
obconically calyciform, narrowing considerably towards the base, prolonged on each 
side, but externally more than on the side of the neuter flower, into a trian- 
gular, dorsally-keeled, acute point; involucre very obliquely evolute and sub- 
auriculiform ; areola of the neuter flower ovate in outline, acute, sharply bordered, 
the scar punctiform and not swollen. Neuter flowers small, acute, 3'5 mm, long; 
the calyx has a short tube, and three long linear teeth; the corolla is twice 
as long as the calyx. Female flowers narrowly ovate, or ovate-oblong, 5-6 
mm. long, acute when in bud; the calyx is urceolate-ovoid, glabrous, finely 
striate externally and has three broad triangular apiculate lobes; the corolla is 4 longer 
than the calyx, ventricose in its lower third, and has three lanceolate, acute segments; 
the filaments of the stamens are united by their bases, and form an urceole, 
which is connate with the undivided portion of the corolla, and has in the free part six 
broadly triangular, thickish (nectariflous ?), abruptly subulate teeth; anthers (sterile) 
lanceolate-sagittate, shorter by half than the segments of the corolla; ovary 
globular-ovoid; style very short and thick, crowned by the oblong clavate, 
strongly lamellose stigmas. Fruiting perianth almost explanate, but its calyx has a 
brief caudiculate base. Fruit ovoid-elliptical, small, 16-17 mm. long and about 11 
mm. broad, round at the base, narrowly and acutely beaked; scales arranged in 12-15 
longitudinal series, rather dull, not resiniflous, of a cinnamon-brown colour, broader 
than long, narrowly channelled along the centre, and with a narrow, shining, finely 
erosely toothed darker margin ; the point round. ced oblong, slightly flattened, 11-12 
mm, long, 9 mm. broad, 7 mm. thick, rounded at both ends, sparsely pitted; 
albumen slightly ruminated by several rather shallow channels; chalazal fovea 
orbicular, pit-like, not very deep, situated in the centre of the raphal side; embryo 
quite basal. 
Hasrrat.—The Malayan Peninsula. First discovered by Grifith at Malacca; found 
again recently by Seortechini and Sir G, King’s collectors in the district. of Perak 
on the hilis at Larut, at 100—150 m. [Herb. Hort. Caleutt. No. 4774 ($) and 
No. 5919 (¢), on the Gunong Tambung Batak, at about 1,000 m. (Scortechini]; in 
Johore [Ridley No. 11204 (9) and No. 11210 (d) in Herb. Berol.]. 
The Malayan name, according to Scortechini is * Rotang Bachap” or “R. pata- 
pisau," this last ‘ (break-knife)' probably on account of the hardness of its leaf-sheaths 
(pata “to break, » and pisau a “ knife ”). 
Griffith gives for C. leptopus the Malay name of “R. Chinchin,” but this name, 
as far as my knowledge goes, is applied solely to the species furnished with 
membranous rings around the leaf-sheaths (“‘chin-ching ” a ring). Ridley l.c. assigns 
to D. leptopus the names of “R. Bakau” and ‘‘ R. Muruseh," and gives the following 
additional localities :—Singapore : Baket Mandai (Ridley 1670, 3497), Kranji, ete, ; 
Johore: Sungei Zebran (Ridley 11519); Malacca: Sungei Hudang, Bukit Kandong ; 
Selangor: Langkat (Ridley).
