yellow-straw-coloured with a rather broad red-brown marginant line and with a rather 
obtuse point and a finely erosely toothed margin, Seeds 3, with a smooth surface, 
12 mm. in length, convex on the back, and with 2 flat faces which are divided by 
a salient angle on the inner side; albumen equable; embryo basal.

OssERvATIONS.—I have seen of this 3 partial inflorescences with nearly mature 
fruit and the upper part of a leaf, 60 cm. in length, with 6 leaflets (in 3 pairs) 
on each side, This I suppose a radical leaf and as it is not cirriferous, as is usual 
in the Calami of the palustris group to which I would refer C. írispermus, therefore 
very probably the upper leaves are cirriferous. 
C. trispermus is extremely like 0. manilensis, but this has a spheric shortly 
mucronate fruit with fewer and larger scales than in C. írispermus.

DescripTion.—Stem . . . . . Leaves . è Female spadiz large; primary 
spathes . . . . .; secondary spathes tubular, thinly coriaceous, armed in their 
upper part with small hooked prickles, and prolonged at the summit into a lanceolate, 
dorsally keeled, acute point; spikelets large, in one specimen 18 cm. long, thickly 
vermicular, cylindraceous, inserted just at the mouth of their own spathes, with about 
15 flowers on each side; spathels shortly tubular-infundibuliform or obconie, 5-6 mm, 
long, slightly asymmetrical, entire, ciliate and exactly truncate at the mouth, where 
6-7 mm. in diam., slightly apiculate at one side, unarmed, furfuraceous; involucro- 
phorum laterally attached in the hollowed base of the spathel above its own and exsert 
from this, two-keeled and with two prominent acute teeth on the side next to the 
axis; involucre irregularly cupular, deeply excavate and acutely bidentate on the 
side of the neuter flower of which the areola is lunate and sharply bordered. Female 
flowers flatly bifarious, rather distant, 5 mm. long. Fruiting perianth explanate (not 
pedicelliform), the calyx split almost to the base into 3 ovate, rather acute, thinly 
coriaceous parts; segments of the corolla lanceolate-acute, as long as the calyx; 
stamens with filaments united by their bases and forming a short ring, suddenly 
contracted, linear-subulate in the free part. Fruit globose, 15-17 mm. in diam., the 
base round, the top slightly depressed and shortly mucronate ; pericarp very thin 
and brittle; scales not very numerous in 12 longitudinal series, each series of 
about 6 well-conformed scales, taking no account of the smaller ones of the base
