92 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (C. Samian. 
spherical, about 11 mm. in diameter, rather regularly and minutely foveolate all 
round, without a distinct chalazal fovea; albumen very deeply ruminated. 
Hanrríar.— The Philippines: Mindoro, on Mount Halcon at about 1,500 m. 
elevation, collected by JM. ZL. Merritt in June 1906 (Herb. Forestry Bureau, Manila, 
- No, 4400). 
OBSERVATIONS.—A very peculiar species belonging to the group of C. palustris, but 
with the seed having a ruminate albumen and with the leaflets equidistant, lanceolate, ` 
5-costulate. It seems related to €. Arugda. Of this plant [ have seen only 
a leaf, the summit of a spadix, and a few fruits.

Merritt No. 4400 in the Herbarium of the Forestry Bureau at Manila, 
147c. Catamus Samian Becc. n. sp. 
Descrirtion.—Scandent, mediuma sized, Sheathed stem 2°5-3 cm. in diameter. 
Leafsheaths slightly gibbous or plicate above, obliquely truncate at their mouths, 
armed rather densely, especially in their upper part, with feeble, light-coloured, 
almost regularly scattered, ascendent spines, which have a small bulbous base, 
and a slender, needle-like, 5-12 mm. long point; the margin of the mouth, and 
the very short ligula, are fringed with similar or somewhat longer spines, 
Leaves elongate, about 2m. long in the pinniferous part and extended into a 
cirrus about 1 m. long, or, at times, longer; the petiole is about 15 em. long 
and 15 mm. broad at the base, strongly flattened, bisonvex, with rather» sharp 
edges, and armed with small straight ascendent spines on the upper surface and 
at the edges; on the lower surface the petiole has only a few small straight 
spines along the central line ; the rachis in its first portion is flattish or slightly 
convex and is rather broadly grooved at the sides where the leaflets are inserted; 
the upper surface of this first portion is more or less prickly and is armed with a 
line of small remote claws underneath; from about the middie upwards the rachis 
is bifaced, with the salient angle acute and smooth above, while the lower surface is 
very irregularly armed along the centre and at the sides with scattered or more 
or less confluent claws ; the claws of the cirrus are at times solitary, but more 
frequently confluent, 2-5 in number, seldom however approximate in regular half- 
whorls ; leaflets very numerous, sub-equidistant, 2:5—3:5 cm. apart on each side of 
the rachis, inserted at. a rather acute angle, concolorous and rather dull on 
both surfaces, thinly papyraceous, very narrowly lanceolate, broadest a little 
below the middle, and thence long-acuminate upwards, to a minutely bristly 
spinulous tip, and downwards tapering to an acute base,  subtrieostulate or 
with a rather conspicuous mid-costa with one very slender costula on each side 
of it: in addition one or two secondary nerves on each side of the mid-costa 
are slightly less prominent than the side-costae; the 3 main costae are bristly 
spinulous from the middle upwards on the upper surface; transverse veinlets, rather 
sharp above, much interrupted; margins spinulous-serrulate; the undersurface is 
quite smooth; the intermediate leaflets are 25-27 cm. long, and 20-22 mm. broad:
