398 ANNALS. OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. formosanus. 
apex; this triangular and rather acute. Seed small, subglobose, 5 mm. in diam., 
deeply and broadly pitted on the back; albumen subruminate; embryo basal, 
Hasrrat.—Lower Philippines: in the Island of Malanipa, discovered in 1875 by 
Mr. H. W. Moseley during the expedition of the Challenger (female Specimen in 
Herb. Kew); in Mindanao at San Ramon, district of Zamboanga, H. Hallier Febr. 
1904, male specimen in Herb. Manilla. 
OssERvATIoNS.— The species is founded on Mr, Moseley's specimen which is only 
the intermediate portion of a leaf and upper part of a fruiting spadix, 40 cm. 
in length, with 4 partial inflorescences. The description of the male spadix has 
been written from Hallier’s specimen which I have considered as conspecific with 
the other, because it comes from the same region, does not offer appreciable differ- 
ences in the leaves from the type and because the male flowers offer the general 
characters of the other species of the group to which C. Moseleyanus belongs, 
In Hallier’s specimen the leaflets are lanceolate-elliptic, acuminate to a densely bristly 
tip, 6:5-10 cm. apart on each side of the rachis, 38 em. long, 3:5-4 cm. broad 
with 5 costulae of which the 2 near each margin evanescent towards the apex and 
smooth, and the other 2 carrying small black spinules in the upper surface; the 
rachis is armed beneath with very robust black-tipped digitate claws; the cirrus is 
long and robust and armed at rather short intervals with half-whorls of almost 
entirely black claws. 
Prate 171,—Calamus Moseleyanus Bece. Intermediate portion of a leaf; the 
summit of a spadix with mature fruit; detached spikelets and seeds.—From Moseley's 
type-specimen in Herb. Kew.

Descrirtion.—Very probably scandent, of moderate or rather large size. Sheathed 
stem 3-3°5 cm. in diam. Leaf-sheaths light coloured (when dry) strongly gibbous and 
unarmed above, otherwise rather densely covered with subulate, flat, laminar spines, 
which vary from 1-2 em. in length, have a broad and somewhat concave base 
underneath and are of the colour of the sheath with a darker point; the mouth is 
armed with pale spines, slender and longer than the others. Ocrea indistinct. Leaves 
cirriferous, more than 1 m. long in the pinniferous part, the cirrus itself measuring 
about another metre and armed with half-whorls of 3-5 and upwards 2-whorls of 
6-7 confluent black-tipped claws; petiole very short, about 2 cm. long, flat above, 
convex or with an obtuse angle beneath, armed at the sides with a few straight 
spines; the rachis glabrous, subshining, finely striate, armed also at the sides like the - 
petiole, roundish and almost smooth beneath in its first portion, and armed upwards 
with at first solitary and then ternate black-tipped claws; in the upper surface it is 
flattish and densely covered with short straight spines in the first portion, while in 
the intermediate one is irregularly trigonous in section, bifaced above with the upper 
salient angle smooth and not very acute; leaflets not very numerous, 18 on each 
side in one specimen, inequidistant, distinctly geminate or ternate on each side of 
the rachis; the fascicles alternate or subopposite, often with a solitary leaflet
