C. multinervis.) BECCARI. THE SPECIES OF CALAMUS.—SUPPLEMENT. 89 
panicle composed of several alternate partial inflorescences, and borne on a 
peduncular part about 45 cm. long, which is flexuose, somewhat flattened, and 
closely sheathed with 3 spathes; the lowest of these is 15 mm. broad and acutely 
two-edged, while the other two have the edges obtuse; all the primary spathes are 
obliquely-truncate at the mouths, and produced at one side into a triangular 
acuminate point, acutely keeled on the back, and with the keel more or less armed 
with small claws; the upper spathes are very similar to the lower ones, but are 
gradually shorter, cylindraceous above, and flat on the inner side at their bases; 
partial inflorescences inserted a little above the mouths of their respective spathes 
with a distinct axillary callus; the lower partial inflorescences are about 50 cm. 
long and bear distichally about ten spikelets on each side: the upper are somewhat 
reduced in length and number of spikelets; secondary spathes very narrowly infundi- 
buliform, smooth, obliquely truncate and ciliate (deciduously) at the mouth, produced 
at one side into a triangular acute point; spikelets inserted just at the mouth of 
their respective spathes: the lower and largest are about 6 cm. long and have 
]0-12 flowers on each side, the others gradually shorter and with fewer flowers: their 
axis slender, but the spathes relatively broad, concave-subcupular, apiculate on one 
side; involucrophorum almost explanate, somewhat irregular, almost laterally adnate 
so the base of the spathel above its own; involucre concave-subcupular, irregular 
and more or less bi-dentate on the side of the areola ot the neuter flower; this 
areola is conspicuous, very distinctly lunate, and sharply edged; spathels and involucre 
ciliate on the edges. Female flowers small, about 3 mm. long; the calyx 
parted down past the middle into 3 triangular acute lobes; the apices of the 
segments of the corolla are exactly level with the teeth of the calyx. Fruiting 
perianth not quite explanate under the fruit, but not pedicelliform. Fruit globose- 
ovoid, shortly conically beaked and 6 mm. in diameter when not quite mature, 
apparently however it remains always very small; scales squarrose, arranged in 15 
longitudinal series, flat, not grooved along the centre, of a dirty straw-colour on 
the posticous part, and with black margins and apex which is somewhat produced 
and erosely toothed, Seed. 
Hansrram.— The Philippines: Island of Mindanao, district of Davao. The male 
plant collected by Elmer at about 1,200 m. on Mount Burebid, Oct. 1909 (No. 11955), 
Native name “Balafa”’ The female plant, with immature fruits, has been collected 
also by Elmer, in the same district of Davao in September 1909 (No. 11791), 
in moist rich soil of a deeply forested flat at about 1,200 m., south of Bariring 
River. Native name '*Ubbli." 
OsnsERVATIONS.--It is apparently related to ©. Reyesianus from which it differs: 
in its larger size; in its smooth leaf-sheath; im the more elongate pluricostulate 
leaflets; in the larger spadix with smooth secondary spathes, and possibly also in 
the considerably smaller fruit, but the fruit is not fully developed in the 
specimens available.
