102 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA [C. mucronatus. 
edged. Female flowers conical, at the time of the anthesis 5 mm. long; the calyx 
striately veined, shortly 3-toothed; the lobes of the corolla acute, very slightly longer 
than the calyx; stigmata circinate, slender, conspicuously projecting beyond the 
narrow apex of the corolla. Fruit ovoid—elliptical, distinctly conically beaked, about 
lem. long (perianth and beak included); scales in 12 longitudinal series, concolo- 
rous, blackish, narrowly and deeply grooved along the centre, the point triangular 
bluntish, the margins very narrowly scarious and very minutely erose ciliolate. 
Seed ovoid-elliptic, its surface even (not pitted); chalazal fovea orbicular in the 
centre of the raphal side; embryo about central on the other side; albumen equable. 
Fruiting perianth campanulate, slightly pedicelliform from the hardened and sub- 
callous base of the calyx, which is deeply split into 3 lobes, broader than the 
segments of the slightly longer corolla. 
O. brevispadiz is rather closely related to 0. viridispinus, from which it differs. in 
its shorter and more stiff spadix and in its fruit with blackish scales. In @. viridi- 
spinus the scales are light straw—coloured. 
Wray’s No. 3923, upon which I had founded C. bubuensis and of which I have - 
seen other more complete specimens than that figured in my plate 183, differs from 
Ridley's type of C. brevispadir in being somewhat smaller in every part, iu having 
the leaflets with smooth margins and nerves, and perhaps also in the female flower- 
slightly shorter and more broadly conieal. I probably applied provisionally the name 
of C. elegans to Wray’s specimens in the Herbarium at Kew. 
Ridley collected his specimens of C. brevispadiz (No. 12121) in Selangor, Semang- 
kok Pass, at about 1,200 m. elevation. 
SurPL, Prate 57, Calamus — brevispadix Ridley.—Fruiting spadix; female 
spadix in flower; upper part of a leaf-sheath and petiole; intermediate portion of 
a leaf. From Ridley’s No. 1<121 in the Herbarium at Singapore.

O. elegans Bece. mss, ex Ridley lc. as regard Wray's No. 3923, of which I 
had made a C. bubuensw, is the male plant of C. brevispadiz, as I have already 
explained under this species. 
155. CALAMUS MUCRONATUS Becc. 
To what I have already written about this graceful and very distinct species, 
I have now to add the description of the female spadix, from specimens collected 
by H. Hallier in Dutch N. W. Borneo at Gunong Semedum, Residency of Sambas 
(No. 704 in Buitenzorg Herbarium), and in Sarawak at Siul by J. Hewitt (in Kew 
Herbarium). The female spadiz terminates in a very short, very slender, unarmed 
appendage, is shorter than the leaf above which it is inserted, and is 30-40 em, 
long, with 3-5 small partial inflorescences; primary spathes elongate, tubular, 
sheathing, smooth, or very slightly prickly, more or less fugaciously rusty-furfuraceous 
ciliate-bearded at the mouth, and produced there at one side to an acuminate poitit 
the partial inflorescences are 5-10 cm. long, and have few (4-7 in all) small spikelets ;
