C. Reyesianus,] BECCARI. THE SPECIES oF CALAMUS.—SUPPLEMENT. 87 
sheaths; near the mouth of the sheaths the spines are more crowded and some- 
what longer; ocrea obsolete. Leaves of the adult plant large; an intermediate portion 
of one has the rachis almost bi-convex, smooth below, and armed above with small 
scattered erect prickles; leaflets inequidistant, approximate in pairs on each side of 
the rachis, narrowly elliptic or  elliptic-lanceolate, 22:25 cm. long,  6-6*5 em. 
broad, firmly papyraceous, concavo-convex, acute at the base, rather suddenly con- 
tracted above into a shortly acuminate and at the sides bristly-spinulous apex, 
almost glossy on the upper surface, slightly paler underneath; they have 5 slender costae 
and several secondary nerves often not very distinct from the costae; all the nerves 
are smooth on both surfaces except on the mid-costa above near the base where 1—2 
small rigid spines are usually present; transverse  veinlets very fine, approximate 
and subparallel; margins minutely spinulous. Male spadiz . . . . Female spadiz 
non-cirriferous, rather short, diffusedly paniculate, terminating in a small taillike 
flattened, spinulous appendage ; primary spathes very closely sheathing, thinly coriace- 
ous, elongate-infundibuliform, densely armed on their upper part with small, straight, 
horizontal spines, flat on the axial side, obliquely-truneate and entire at the mouth, 
where they are produced at one side into an elongate triangular point, which is 
keeled posteriorly. Partial inflorescences divaricate, 18-0 cm. long, with 5-6 spikelets 
on each side; secondary spathes narrowly infundibular, armed with a few, small, 
horizontal, straight spines on their back at the summit, obliquely truncate, entire and 
fringed with decidulous paleolae at their mouths, and produced at one side into a 
triangular acute point; spikelets erecto-patent, inserted just above the mouth of 
their respective spathes, the largest 8-10 cm. in length, with 12-16 distichously 
arranged flowers on each side; spathels shallowly and obliquely infundibular, 
shortly apiculate at one side, the point usually provided below with a small spine ; 
the margin of the spathels is entire and fringed with deciduous paleolae; involucro- 
phorum concave, very shallow, immersed within its own spathel, produced externally 
into a triangular point, which subtends the neuter flower; involucre shallowly and 
asymmetrically jcupular, bidentate and lunately excavate on the side of the neuter 
flower, of which the areola is comparatively large, lunate and sharply edged. 
Fruiting perianth not forming a pedicel, very broadly obconic or almost explanate, 
Fruit spherical, surmounted by a very short beak, 15 mm. in diameter; scales in 
18 longitudinal series, of a  reddish straw-yellow colour, with a narrow darker 
intramarginal line and scarious, finely erosely-tcothed margins, rather convex, broadly 
and rather deeply grooved and with a triangular rather obtuse point. Seed 
globular, 10-11 mm. in diameter, with a not very closely pitted surface; the 
chalazal fovea indistinct and very superficial; albumen ruminate; embryo basal. 
Hasrrar.— The Philippines. The type specimen was collected in October 1904 
by OC. Reyes at Unisan, in the Province of Tayabas, Luzon. It has been found 
again by M. Ramos in March 1911 at Tagcauayan, also in the Province of Tayabas 
No. 13312 in the Manila Herbarium—a specimen with very young fruits and portion 
of an adult leaf. 
OxsrRvaTions.—The type specimen is the terminal part of a fruiting spadix 
only. C. Reyesianus belongs to the group of C. palustris, but is at once distinguished 
by its perfectly spherical fruit. I have completed the description already given in
