G. impar.) BECCARI. THE SPECIES OF CALAMUS.—SUPPLEMENT 19 
into account the mucro—and is 8 mm, broad. Scales arranged in 15 longitudina 
series, of an almost uniform greenish-yellow colour with a lighter marginal 
line and occasionally slightly tinged with reddish brown at the apex; they are gibbous 
on their posticous part and depressed towards the apex, and are deeply grooved 
along the centre; the apex is blunt and—like the margin—obsoletely and finely 
erose-ciliolate. Seed oblong, 8 mm. long, 5 mm. broad and a little less thick; 
chalazal fovea  suborbicular and situated in the centre of the side which is 
flattish, while the other side is convex on the whole but presents 4-5 slightly 
concave facets; albumen homogeneous; embryo basal. Fruiting pertanth almost entirely 
explanate; the calyx parted down to the middle into 3 broad triangular lobes and 
obtusely veined-costulate; the divisions of the corolla are lanceolate-acuminate, dull 
outside and about one and a half times longer than the calyx.

DrscniPTION.—Secandent, very slender. Sheathed stem 5-6 mm, in diameter, Leaf-sheaths 
slightly gibbous above, more or less distinctly striate longitudinally, appressedly and 
fugaciously furfuraceous, quite smooth or sparingly armed with very short, triangular, 
slightly ascendant spines. Ocrea cylindrical, truncate, 10-15 mm. long, striate, 
glabrescent or sparingly furfuraceous, membranous, later dry and brittle. ^ Leaf-sheath 
flagella very slender, thread-like. Leaves very small, 15-20 cm. long on the whole, 
usually with only 4 leaflets, of which the two terminal are connate for two-thirds 
or half their length, one is in immediate proximity to the terminal pair, and the 
other is only 15-25 mm. below that and is solitary on the other side of the 
rachis; rarely to this solitary leaflet is opposed another; petiole and rachis on the 
whole 5-7 cm. long; the petiole is subterete, very narrowly grooved on the upper 
surface, armed along the centre of the dorsum with a few small solitary claws, 
Leaflets papyraceous, very rigid, almost glossy on the upper surface, duller and 
slightly paler underneath, all very sharply 3-costulate, lanceolate or narrowly ovate 
elliptical, somewhat cancavo-convex, almost equally tapering and acute at both ends; 
the nerves on both surfaces and on the margins are quite smooth; transverse 
veinlets rather sharp, parallel and rather approximate; the side leaflets are 7-12 
cm. long, 15-25 mm. broad, the two of the terminal pair, which are united to 
form a cuneiform flabellum, are longer and broader than the others (15-18 cm. long, 
8:5-4 cm. broad and very suddenly apiculate. Male spadiz slender, longer than the 
leaves; it has very few remote spreading partial inflorescences; the pedicellar part 
with its spathe is flattened and smooth; the primary upper spathes are very strictly 
sheathing, truncate at the mouth, armed with very small claws; partial inflorescences 
spreading, with only 2-3 horizontal spikelets on each side; secondary spathes very 
strictly sheathing, smooth; spikelets filiform, their axes terete and sinuous between 
the flowers, 2-3 cm. long, with 6-8 distichous flowers on each side; spathels 
rather elongate, cylindrical and smooth in their basal part, infundibular and striately 
veined above, truncate at the mouth; involucre cupular, obsoletely toothed, laterally 
attached to the base of the spathel above its own. Male flowers not very close 
together (3-3°5 mm, apart). Other parts unknown.
