BECCARI. 



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 raphal 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 hah-nnensis does not, apparently, differ from some forms of 

 V. 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 938 

 I Herb. Kcw. ), has been rediscovered by A. Lohcr at Montalban, Province of Rizal, 

 LUZON, March, 1906, {No. 7087 in Kew 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, wdiich 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 paleoke; the lower partial inflorescences are 30 to 35 cm 

 long with ? or 8 spikelets on each side; the upper are shorter, and have 

 fewer spikelets. The lower spikelets arc 5 to 6 cm long, and have 10 to
