D. castaneus | BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 145 
enlarged in the upper half. or third, where in the fruiting stage discoloured, 
decayed and lacerated, armed with small, straight, somewhat deflexed spicules 
which rest on a bulbiform base; partial inflorescences erect-spreading, 25-35 
cm. long, bearing distichously on each side 8-10 spikelets which are 4-7 cm. 
long and furnished with a slender flattened pedicellar portion (1-1-5 em. long) 
attached to the bottom of their respective spathe; secondary spathes thinly coria- 
ceous or submembranous, tubular-infundibuliform, 1°5-2 cm. long, more or less split 
down to the base, naked or sparingly spiculose, extended at one side into a rather 
long point; spathels shortly infundibuliform, almost auriculiform, acute at one side, 
ultimately more or less split; involucrophorum inserted at the bottom of its res- 
pective spathels, not laterally attached at the base of the one above, spathaceous-auri- 
culiform, acute, dorsally two-keeled ; involucre also spathaceous-auriculiform, acute at 
one side; areola of the neuter flower elongate, lanceolate, sharply bordered. 
Female flowers about 6 mm. long. Fruiting perianth not pedicelliform; its calyx 
and corolla almost similar, divided down to the base into three lanceolate finely 
striate lobes of equal length and breadth; staminodes persistent, reaching to about 
the middle of the corolla with the filaments acuminate from a very broad base 
and furnished with a small sagittate anther. Fruit small, broadly ovate, 12 mm. 
long by 9 mm., very suddenly contracted into a short but thick beak or mucro; 
scales small, in 21 longitudinal series, pale-yellowish, shining, channelled along the 
middle, with brown and finely fimbriate tip. Seed subglobose, slightly compressed, 
flattish or slightly depressed on the raphal side and convex on the back, equally 
rounded at both ends, with equal and not pitted surface, 8 mm. long by 6-65 
mm. thick; albumen homogeneous; embryo basilar, All parts of thé spadix, the 
secondary spathes, spathels and other appendices and parts of the flowers in the 
fruiting stage acquire a chestnut-brown colour when dry, and show traces of a 
tobacco-coloured scurf and are more or less split or lacerated. 
HasrrAT.— The Nicobar Islands, where it was found by Mr. E. H. Man, who 
sent me the specimens described above in August 1888. 
OssERvATIONS,— The leaf I have described was detached from the specimen of 
the spadix, without any reference to this; but the spines with which the petiole is 
armed are very much like those that cover the spathes and show almost certainly 
that this leaf belongs to that spadix, and besides that this Calamus is erect or 
bushy and not scandent.
