C. mattanensis.! BECCARI. THE SPECIES OF CALAMUS.—SUPPLEMENT, 111 
liguliform. The leaves have a rather long petiole, are 35-40 cm. long in the pinni- 
ferous part, and terminate in a clawed cirrus 40-50 cm, long; the petiole is 15-16 cm. 
long, 4-5 mm. broad, glabrous, smooth, flattened, with rather sharp edges, which 
are armed with a very few, at times rather large, straight or hooked spines: it 
is flattish on the upper, slightly convex on the under surface; rachis trigonous, 
armed underneath with solitary claws, which only become first geminate, and then 
ternate, towards the cirrus, bifaced and with a sharp salient angle on the upper 
surface ; leaflets few ‘12-16 in all, distinctly aggregated into 3-4 widely spaced 
groups; the groups 8-15 em. apart, are formed by two very approximate leaflets 
on each side of the rachis, the pairs of one side usually opposite to those of the 
other side, or nearly so; the leaflets are rather firmly papyraceous, concolorous and 
rather dull on both surfaces, yellowish-green when dry, often marked by a glossy 
band along one of the margins; they are linear, narrow, almost all of one size, 
20-30 cm. long, 10-12 mm. broad, sharply  unicostate, more or less acuminate 
to a bristly tip, and with the base acute and plicate; secondary nerves slender, 
unequal, all smooth; transverse  veinlets numerous, but usually not very sharp; 
margins acute, very inconspicuously and remotely spinulous or almost smooth. Male 
spaaiz. . « . . Female spadiz very similar to that of C. ferrugineus and also 
covered with a rusty-furfuraceous scurf which however does not leave a scabrid 
surface .after it has fallen; the spadix is short (35-40 cm. long), rigid, slender, 
not flagelliform, has but few (5-6) partial inflorescences, and terminates in a small 
unarmed tail-like appendage; the peduncular part of the spadix is 8-16 em. long, 
strongly flattened, acutely two-edged, unarmed or nearly so; primary spathes 
tubular, slightly |flattened, somewhat enlarged in their upper part, or  elongate- 
infundibuliform, keeled on the back (the keel smooth, or armed with a few very 
small claws) obliquely truncate, entire, and. densely ciliate-bearded at the mouth, 
prolonged at one side into a triangular, acuminate, erect point; partial inflorescences 
inserted, at the mouth of their own spathes, curved downwards, small; the lower 
(largest) are about 6 cm. long and have only 2-3 alternate subunilateral spikelets 
on each side; upper partial inflorescences gradually smaller ; secondary spathes infundi- 
buliform, rendered more or less angular by wutuai pressure, tomentose, ciliate, 
barbate at the mouth, and prolonged at one side into a short point ; spikelets 
subscorpioid, inserted just at the mouth of their own spathes: the lower (largest) 
are 15-20 mm, long, and have 2 series of assurgent approximate . female and 2 
other series of deciduous, smaller neuter flowers (each series of 3—4 flowers); upper 
spikelets gradually shorter, and with fewer flowers; spathels short, bracteiform, 
concave, very broad, acute, deflexed, hairy and ciliate; k; involucrophorum 
explanate, Hiseni trai involucre explauate, calyculiform, irregularly and acutely - 
3-toothed ; areola of the neuter flower very depressedly lunate. Female flowers 
are secundly arranged (are not flatly bifarious', are about 3 mm. long, ovoid- 
pyramidate, and have a flat base. Neuter flowers similar to the males, but smaller. 
Fruiting perianth shortly yet distinctly .pedicelliform; the calyx indurated, 
ventricose and ` smooth in its lower part, with a flat base, divided down. to 
the middle into 3 triangular acute lobes; segments of the corolla triangular, acute 
about as long as but slightly narrower than the lobes of the calyx. Fruit ‘broadly 
ovoid, or slightly obovoid, very abruptly and distinctly beaked, rounded ‘at the 
base, 15 mm. long (including beak. and perianth) 10 mm. broad; scales arranged
