e. wari-watriensis. | BECCARI. THE SPECIES OF CALAMUS.—SUPPLEMENT. 71 
Hansrrar.— The Philippines. The type specimen was collected by Elmer (No. 9298 
in Herb. Beccari) in Luzon at Lucban, Prov. of Tayabas, in dry woods at 800 m. 
Found afterwards in Mindanao also by Elmer (No. 11756 in Herb. Beccari) in 
the district of Davao, on a slightly-wooded ridge at about 1140 m. near the 
junction of the Baruring River with the Calan Creek. I consider No. 7289 (in Herb- 
Beccari) collected by Æ. D. Merrill, also in Mindanao at Agusan River, Butuan sub- 
province, to be conspecific with the above. 
OsnsERVATIONS.— 0, LElmertanus is closely related to C. mitis of the Babuyanes 
Islands, from which it differs in having the leaf-sheaths armed with slender flexible 
spines (in C. mitis the leaf-sheaths are quite unarmed); especially in the thinner 
pericarp of the fruit; in the more numerous and more distinctly squarrose scales 
and in the slightly rugose-pitted surface of the seed. | 
C. Elmerianus seems to be a variable plant as to the arrangement of the leaflets 
along the rachis. in the type specimen the leaflets are distinctly approximate 
in pairs on each side of the rachis, and the pairs are separated by long vacant 
spaces; in Elwmer’s No. 11756 from Mindanao this disposition is less apparent, and 
in Merrill’s No. 7289 the leaflets are only irregularly alternate on each side of 
the rachis. Moreover in No. 11786 from Mindanao the leaflets bear on the 
margins, specially in their lower part, a few unequal, light coloured, very slender 
spines, of which some attain 5-6 mm. in length, but usually are shorter; the leaflets 
have also the mid-costa often spinulous on their upper surface, and the tip smooth 
In Merrill’s No. 7289, also from Mindanao, the leaflets have quite smooth margins 
and the mid-costa is only spinulous above near the base. 
Both OC. mitis and C. Elmerianus approach C. Minczhasse from Celebes.

197 a. CALAMUS WARI-WARIENSIS Becc. n. sp. 
Descriprion.—A_ slender climber. Sheathed stem 12-15 mm. in diameter; internodes 
elongate; naked canes about 8 mm. in diameter. Leaf-sheaths thickish, greenish and 
thinly covered with a rusty-furfuraceous indumentum, armed lower down with rigid 
bristles or with more or less confluent and shortly seriate or else scattered spiculiform 
spinules, which have light tuberculiform bases; in the upper part the sheaths have 
the spiculae gradually transformed into very dark, glossy, rigid, elongate bristles, which 
are more densely set near the mouth and entirely cover the ligule; the latter is really 
liguliform, about 4 cm. long, and is opposed to the petiole, The leaves are 60 cm, 
long in the pinniferous part, and non-cirriferous; the petiole is elongate, about 20 em. 
long and 5 mm, broad, flattened and plano-convex, armed on the upper surface with 
numerous, small, erect prickles, and on the acute margin and along the centre 
of the dorsum with small claws. Zeaflets numerous, equidistant, 18-20 mm. apart, 
linear, very narrow, 15-18 cm. long, 8-10 mm. broad, very acuminate, almos 
uniformly green, with 3 very slender costulae which are bristly on the upper surface 
and quite smooth underneath; margin remotely spinulous; transverse veinlets prominent
