30 ANNALS OF THE ROYAL BOTANIC GARDEN, CALOUT1A (C. melanorhynchus. 
OBSERVATIONS.— C, filispadiz greatly resembles ©. .Hookerianus in the extraordinarily 
elongate spadices, but differs from it in the leaflets which have 3 sharp, distinct, 
eostz slightly bristly on the upper surface and covered throughout on the lower 
with numerous fulvous bristles; it differs also in the fruit being ovoid and not 
spherical, with a more distinctly pedicelliform fruiting perianth, and in the seed 
longer than broad and not orbicular. 
SUPPL. Puare 15.—Calamus filispadix Becc. Sheathed stem with base of a petiole 
and the lower part of a spadix; intermediate portion of a leaf; an entire partial 
inflorescence ; a detached spikelet with the fruits attached. From Curran’s No. 10630 
in Manila Herbarium. 
546, CALAMUS MELANORHYNCHUS Becc. n. sp. 
Description.—High scandent and of middling size. Sheathed stem 3°5-4 cm., the 
canes 2 cm. in diameter. Leaf-sheaths strongly gibbous above, thick and woody, very 
powerfully armed with irregular, horizontal or more or less oblique, incomplete 
rows of large, thinly laminar, very rigid, spreading, triangular, blackish spines 
of which the largest are 12-18 mm. long and 8-12 mm. broad at their base ; 
between the rows of these are other rows of smaller spines, but vf “the same 
description. Leaf-sheath flagella excessively long (about 7 m.—Elmer) Leaves (non- 
cirriferous) about 2 m. long in the pinniferous part; petiole about 25 cm. long, 
2 cm. broad at its base, flat and sparsely prickly, especially along the 
central line, the margins sharp; underneath it is convex and armed with a line 
of solitary claws along the centre and with several subdigitate divergent blackish 
spines near the margins; in its lower portion the rachis has the upper surface 
at first flattish or slightly convex and sprinkled with small erect prickles, and 
from the middle upwards is bifaced with an acute salient sparingly prickly angle; 
underneath it is powerfully and densely armed with single claws along the 
centre and on each side and only near the end the claws become not very 
regularly ternate. Leaflets very numerous, very regularly equidistant, 2-5-3 cm. 
apart, inserted at an angle of about 45°, papyraceous, rigidulous, almost similarly 
greon on both surfaces, linear-lanceolate, broadest far below the middle and from 
thence tapering below to a narrow base and above to a long, acuminate, bristly 
apex; they are conspicuously 3-costulate on the upper surface, the mid-costa is 
very sharp and smooth, while the side coste are slender and provided with a few 
inconspicuous spinules; on the undersurface only the mid-costa is minutely, at times 
rather closely, hairy-spinulous ; transverse veinlets much interrupted ; the margins 
are sometimes slightly thickened by a secondary nerve, which runs along them, and 
are very inconspicuously spinulous, the spinules being remote, very small and 
appressed; the intermediate leaflets are 40-45 cm. long, 2 cm. broad; those near 
the base narrower, but considerably shorter; those of the upper end are gradually 
reduced in length and breadth, the two of the apex being only 7-8 em. long 
and 2-4 mm, broad and quite {free from the base. Male and female spadices 
flagelliform, excessively long, similar as regard the axial and appendicular parts, 
with several partial inflorescences about 1 m. apart, and a very long common 
stalk (1:5 m. long in one specimen) which is very closely sheathed by two
