C. symphysipus. | BECCARI. MONOGRAPH OF THE GENUS. CALAMUS. 347 
unequal horizontal short (1-8 mm. long) spines, 2-3 of them often conflúnni 
by their broad bases; rachis bifaced above from the middle upwards, rounded 
in the lower surface in the intermediate portion, where armed at regular intervals. 
along the middle and irregularly along the margins with solitary claws, these 
ternate and gradually smaller towards the summit; leaflets numerous, remotely 
inequidistant, but apparently not fascicled, though whereas a few are regularly set 
3-4 cm. apart one from the other, the following may be 10 cm. distant, 
elliptic-lanceolate or oblanceolate, gradually narrowed to and acute at the base, 
acuminate at the summit, the extreme narrow tip covered with short brown subspiny- 
bristles, papyraceous, rather firm, with 6-7 slender cost, these almost of equal 
strength and all reaching the summit, without bristles or spinules on either surface, 
green, glabrous and subshining above, discolorous underneath, where covered with 
a very thin and very adherent light sub-ochreous coating; transverse veinlets 
crowded and continuous, more sharp above than beneath; margins closely and 
adpressedly spinulous; the largest leaflets, those of the lower and intermediate portion, 
28 cm. long, 5 em. broad, the upper ones speedily decreasing in length, the upper- 
most only 6-10 em. long and 10-15 mm. broad. Male spadiz . . . . . Female 
spadiz rather large and elongate (not seen entire) with many not very remote 
(18-20 cm. apart) partial inflorescences and prolonged into a strongly clawed 
flagellum, this 1 metre in length in one specimen seen by me; lowest primary 
spathe not seen; upper primary spathes tubular-cylindraceous, thinly coriaceous, 
slightly enlarged and loosely sheathing in their upper part where the largest, those 
of the lower portion of the spadix, 12-15 mm. in diam., obliquely truncate and 
prolonged at one side into a short broad point at the mouth, sparingly armed chiefly 
on the back of their upper part with very small subtuberculiform spines; partial 
inflorescences arising erect from inside their respective spathcs, then arched, rather 
short, the lower ones, the largest, about 20 em. long, not very dense, with 10 
spikelets on each side; secondary  spathes tubular-infundibuliform, rather loosely 
sheathing, slightly obliquely truncate and naked at the mouth, apiculate &t one side, 
quite unarmed, faintly striately veined; spikelets inserted above the mouth of their 
own spathe with a distinct axillary callus, spreading, arched scorpioid, their axis 
rigid, filiform, gradually narrowed towards the apex or subulate with two not flatly 
bifarious but slightly assurgent and not very regular series of flowers; the largest 
spikelets 10-12 cm. long with 15-i6 flowers in each series; spathels more or less. 
fugaciously furfuraceous, elongate-infundibuliform, loosely sheathing, finely  striately 
veined, horizontally truncate and entire at the mouth, shortly apiculate at one side, 
gradually smaller from the base of the spikeles to the summit; involucrophorum 
small, flat, discoid, stalked by a slender pedicel, this 2-4 mm. long and attached 
outside its own spathel near the base and sometimes about to the middle of 
the one above, more or less distinctly callous at its axilla; involucre slightly raised 
above the involucrophorum, disciform, subconvex with a narrow annular limb; areola 
of the neuter flower punctiform. Female flowers small, 3 mm. long. Fruiting periantk 
shortly but distinctly pedicelliform, the calyx shortly cylindraceous, finely striately 
veined, teeth patent, very broadly triangular, apiculate; segments of the corolla as 
long as the teeth of the calyx, but a half narrower. Fruit spheric, 1 cm, in diam., 
very shortly mucronulate, scales small, numerous, in about 24 series, subshining, 
slightly channelled along the middle, slightly prolonged into a rather obtuse and not
