C. Cumingianus. | BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 949 
exposed portions of the blade in the praefoliation, Male spadiz . . . . Female 
spadiz ultradecompound (not seen entire) apparently elongate; upper primary spathes 
thinly coriaceous, elongate, cylindraceous, not very closely sheathing, shortly open at the 
summit on the ventral side and prolonged into a short acute point, fugaciously 
furfuraceous, sparingly armed with scattered, very small, short slender and scattered 
prickles; partial inflorescences arising erect from inside their own spathes, then arched, 
loosely panicled-pyramidate, subscorpioid; the one seen by me 15 cm. long, bearing 
at its base a few branchlets (or branched spikelets) 5-6 cm. long and higher up 3-4, 
gradually diminishing, simple spikelets; secondary spathes thin in texture, almost 
membranous, infundibular, loosely sheathing, finely striately veined, fugaciously furfura- 
ceous, ciliate, truncate and obsoletely 3-dentate at the mouth; spikelets very unequal, 
with very slender and brittle axes, the lower ones, the largest, 2-2°5 cm. long, with 
very few remote flowers on each side, the upper ones shorter and very few-flowered; 
spathels membranous, fugaciously furfuraceous, infundibuliform, narrow at the base, 
broadened and loosely sheathing in their upper part, very finely and sharply veined, 
truncate and acute at one side at the mouth; involucrophorum small, calyculiform, 
propped by a slender pedicel 1-2 cm. long, attached at the mouth of its own 
spathel ‘at the base of the one above; involucre slightly raised above the involu- 
crophorum, larger than this, calyculiform, more or less acutely bidentate on the 
outer side; areola of the neuter flower punctiform, often furnished with a small 
bracteiform scale. Female flowers ovate, 3 mm. long; the calyx thin, submembranous, 
ovoid-urceolate, sharply striately veined, superficially and broadly 3-toothed; the 
corolla barely longer, divided down to the middle into 3 broad triangular acute 
thin connivent segments; stamens with the filaments united by their bases into a 
high membranous urceolum which reaches to or above the middle of the corolla 
and is truncate and crowned by 6 separate (not in contact by their slightly 
broadened bases) linear short teeth; sterile anthers deeply sagittate; ovary obovate, 
tapering towards the base; style 0; stigmata thick  elongate-triangular, lamellose- 
tubercled inside, spreading during anthesis. Neuter flowers slender, 3:5-4 mm. long; 
the calyx subcampanulate, broadly 3-toothed, the corolla twice and half as long as 
the calyx, both finely striately veined. Fruit unknown.

Oxservations.—The description is taken from the specimen of an intermediate 
portion of a leaf and a portion with only a partial inflorescence of a female spadix 
in flower. Notwithstanding these scanty materials, the species appears a very distinct 
one, only related to C. symphysipus and C. heteracanthus and easily distinguishable 
by its spathulate, opaque, not discolorous, many-costate leaflets, which are clustered 
into alternate groups of 2-4 on each side of the rachis and by the female flowers 
with a long-stalked involucrophorum.
