116 ANNALS OF THE ROYAL BOTANIC GaRDEN, CALCUTTA. [C. aleonensis. 
the lower ones are branched, Fruit narrowly ellipsoidal, conically beaked, 10-11 mm, 
long (including the perianth) 5 mm. broad; seales in 14-15 longitudinal series, glossy, 
straw-yellowish, faintly grooved along the centre, the point triangular, slightly  pro- 
duced, erosely toothed, not very appressed or subsquarrose. 
Hasitat.--The Philippines: Batanes, Batan Island at St. Domingo de Basco, 
Collected by Æ. Féniz in June 1907, with immature fruit (No. 3611 in Herb. Manila). 
OBSERVATIONS.— It differs from the type especially in its narrower and less inflated 
spathes, in the small partial inflorescences, and in the more elongate ellipsoid 
fruit. 
186. CALAMUS MICROCARPUS Bece. Add:—Bece. in Phipp. Journ. Science, iv, 
(1909), 627 and vi, (1911), 230. 
This very variable species is a very near ally of C. siphonospathus, from which 
however, it seems to me always distinguishable by the fruit, which in O. microcarpus 
is covered with scales very deeply grooved along the centre and gibbous on the 
point, which is very appressed to the following scales, while in C. siphonospathus the 
scales are subsquarrose and slightly grooved. From the flowers alone it is difficult 
to distinguish the two species from one another. ‘lhe fruit of (. microcarpus varies 
somewhat in size, probably also, to a certain extent, on account of its degree of 
maturity. The disposition of the leaflets is also very variable; they are asually 
regularly set in the lower part of the leaf, and more or less distinctly grouped 
towards the end. " 
To the localities are to be added the following: Mount Alban, Province of 
Rizal, Luzon (ZLoher in Kew Herbarium,); Mount Maquiling, Province of Laguna, Luzon 
(F. Tamesis No. 13305 Herb. Forestry Bureau, Manila: this specimen bears 
thoroughly mature fruits, ovoid, 9-11 mm, long, 8 mm. broad; the seed is ovoid, 
7-8 mm. long, 6 mm. broad and 5 mm. thick, being slightly flattened). Luzon, Province 
of Tayabas (Foxworthy No. 12326 in Manila Herbarium: specimen with ovoid- 
elliptical fruit, 12 mm. long, 7 mm. broad; the seed is also proportionately elongate) ; 
Mindanao, Camp Keithley, Lake Lanao (Mrs. Mary Strong Clemens, October 1907, 
no number in the Manila Herbarium: this specimen is very similar to the type specimens 
of Vidal; the fruits are broadly ovoid or subglobular-ovoid, 10 mm. long, not 
including the pedicelliform perianth; the seed is globular or slightly longer than 
broad, 6 mm. long, ard at times very slightly flattened); Mindanao at Todaya on 
Mount Apo (Eimer No. 11676 in Herb. Beccari: specimen in fruit very similar to the 
preceding, vern. name ''Pareti": apparently it is the same as another specimen with 
female flowers, collected in the same locality with the No. 116529 and bearing the 
native name **Obanoban"); Island of Polillo (Robinson No. 9131 Herb. Manila vern. 
name ‘‘Bungang sipay "); also McGregor (No. 10465 Herb. Manila: in this specimen 
the fruits are quite mature: they are ovoid, 11 mm. long, not including the 
perianth, 8 mm. broad: seed ovoid, 7:5 mm. long, 6 mm, broad, 5 mm. thick, being 
slightly flattened).
