long, including the perianth, 12 mm broad; scales in 12 longitudinal 
series, polished, of a dirty straw color, with a paler, narrow, scarious 
margin, deeply furrowed in the middle quite to the point, and almost 
bigibbous, their apices blunt and with a blackish spot. Seed ovoid, 10.5 
mm long, 7 mm broad, broadly pitted and irregularly grooved, rather 
deeply furrowed on the rapha.l side, and without a chalazal fovea.

I have seen of this plant only a very incomplete specimen of the leaf-sheath 
and leaves, an entire spadix, and a few fruits ; and these were detached from the 
spadix, although to all appearances, they really belonged to it. In the vegetative 
organs, Calamus halconensis does not, apparently, differ from some forms of 
C. dimorphacanthus, but the fruit is of different type, and resembles more that of 
C. microcarpus.

This, which was an imperfectly known species described by me from Vidal 93S 
(Herb. Ivew. ), has been rediscovered by A. Lolier at Montalban, Province of Rizal, 
Luzon, March, 1906, (No. 7081 in Ivew Herbarium). 
In Loher’s specimen the sheathed stem is 2 cm in diameter, the leaf- 
sheaths are greenish or purplish-green, gibbous above, feebly armed with 
very small, straight, broad-based spines, 2 to 3 mm long; the mouth is 
truncate and fringed with scales and few spinules. One leaf is 1.6 m 
long in the pinniferous part, and terminates in a rather long, robust, 
and strongly clawed cirrus; the petiole is quite obsolete; the leaflets 
are about 30 on each side, rather approximate and equidistant in the 
lower part of the rachis, more distant and somewhat irregularly arranged 
above ; the medials are 30 to 32 cm long and 20 to 25 mm broad and are 
usually furnished, near the base of the mid-costa on the upper surface, 
with 1 or 2 spinules; these are more robust than some which stand 
higher up ; one nerve on each side of the mid-costa, is also more or less 
spinulous, but occasionally a single nerve on one side only is so; under- 
neath all nerves are naked; the rachis on the upper surface of its lower 
portion, is armed with unequal, erect spines, which disappear higher up, 
where the rachis is bifacial, with the salient angle very obtuse; under- 
neath, the rachis is smooth in its basal part but toward the end is armed 
with claws, which are single at first, then geminate, and are finally set 
in half-whorls. The spadix is erect, diffuse, 90 cm long, with only 4 or 
5 partial inflorescences on each side, and terminates in a short tail-like 
prickly appendix; the lowest spathe is flattened, two-edged, 12 cm long; 
all the other primary and secondary spathes are fringed at the mouth 
with small paleolaa; the lower partial inflorescences are 30 to 35 cm 
long with 7 or 8 spikelets on each side; the upper are shorter, and have 
fewer spikelets. The lower spikelets are 5 to 6 cm long, and have 10 to
