l77a. CALAMUS KEYENSIS Beec. n. sp. 
DzscRiPTION, — Apparently scandent and of moderate size. Skheathed stem , . . 
Leaf-sheaths . . . Leaves rather large: the one I have seen, wanting its basal part 
ony, is 166 m. long, subcirriferous, the uppermost leaflets being gradually greatly 
reduced in size, til the ultimate ones are almost rudimentary; the rachis is 
robust, 1 em. broad in its lowest part, covered with fugacious scanty greyish 
scurf: the upper surface is smooth throughout, flattish in its lower part, but higher 
up has a salient angle which is obtuse at first and finally acute; the lower 
surface of the rachis is slightly convex and powerfully armed with robust claws, 
which have light-coloured bases and black tips and are somewhat irregularly set, 
and usually ternate, at a nearly regular distance of about 3 em,; the spaces however 
become less, and the claws gradually smaller towards the end.  Leajlets equidistant, 
firmly papyraceous, rigid, green on both surfaces, lanceolate, tapering from below 
the middie down to an acute base and upwards rather briefly to a subulate 
bristly tip: they are  plicate-pluricostulate and somewhat concavo-convex ; the mid- 
costa is slender but acute on the upper surface and is usually furnished with a 
small spinule near the base, otherwise both surfaces are smooth ; ‘the side 
costae are very slender, 4-5 on each side, unequal and barely distinguishable from 
a few other secondary nerves; transverse veinlets very sharp and numerous; margins 
remotely and appressediy spinulous, the spinules being transformed into short 
blackish bristles at the apex; the middie leaflets are 6-7 cm. apart, 80-32 em. 
long, 3:5-5 cm. broad; towards the end the leaflets become gradually smaller and 
more closely set, the ultimate ones being only 2-3 cm. long and 4-6 mm. broad. 
Male spadiz . . . Female spadiz apparently rather large (not seen entire): it has 
several gradually decreasing partial inflorescences, which form short and dense scorpioid 
panicles of which the largest of those seen by me is about 12 em. long, and 
has 5-6 gradually decreasing, arched, very slender, scorpioid branchlets on each 
side, inserted a little above the mouths of their respective spathes; primary 
Spathes . . .; secondary spathes tubular, very closely sheathing, fugaciously furfura- 
ceous, later glabrous, finely striately veined, unarmed, truncate and naked at the 
mouths, prolonged at one side to an acuminate point; the lower branchlets are 
4-5 em. long and carry a very few subunilateral spikelets of which only those near 
the base carry -6 flowers on each side, the successive spikelets having fewer and 
fewer flowers, till finally the uppermost are reduced to a single flower ; tertiary spathes 
narrowly tubular-infundibuliform, very closely sheathing, striately veined, prolonged at 
one side into a finely acuminate point; spathels similar to the tertiary spathes, but 
their apices subtend their respective flowers, which are suffulted by a distinct pedicelli- 
form involucrophorum; the latter is obconie with a very slender neck, is on the whole > 
1-15 mm. long, kept spreading by a distinct axillary callus; involucre orbicular 
discoid, entire, flattish, slightly raised above the involucrophorum; areola of the 
neuter flower punctiform. Fruit spherical, pisiform, 7-7:5 mm. in diameter, very 
shortly and obtusely beaked; scales very small and numerous, Squarrose, arranged 
in 24 longitudinal series, rhomboidal, the point obtuse, very slightly convex, not 
grooved along the centre, straw-coloured with narrow reddish-brown edges and 
very minutely fringed ciliate margins. Seed globose, 5 mm. in diameter, with an 
even (non-pitted; surface; chalazal fovea elliptical in the centre of the raphal
