mid-costa above, but beneath have the mid -costa closely bristly and the side 

 nerves naked. In the Malayan forms the leaflets have long bristles on 3 nerves 

 beneath, the mid-cost a being smooth, while the mid-costa above is bristly. The 

 female spikelets of this variety are also less distinctly zigzag-sinuons. the invo- 

 lucre of the Bower does not form so regular and deep a cup as in the type and the 

 areola of the neuter flower is crescent-shaped and not roundish. Otherwise the 

 similarity of the Philippine variety to the Malayan type is very evident. 



The male plant was collected by F. H . FoatPOfthy in March, l'.MIti. on Mount 

 Victoria, Palawan. [Bur. 8oi. No. 756), and the female by Loher, in Luzon, at 

 Montalban. Province of Kizal. March. 1906, (No. 111 1 ,.', in Herb. Kew. I . \. v. 

 palimanac. 



The male specimen has a leaf 1).5 m long; the Leaflets are numerous, 

 equidistant, subtricostulate, the mid-costa is rather prominent, above 



bristly-spinulous near the apex, the side costae with long bristles; under- 

 neath the mid-costa is furnished with bristles, and the side nerves arc 

 naked. The male Bpadix is, as in the species, extraordinarily long, and 

 not essentially different from that oi the Malayan type; hut the secondary 

 and tertiary branches and the spikelets are inserted just at the mouth 

 of their respective spathes, and these terminate in a broad, horizontal 

 or deflexed point. The male flowers also are slightly smaller, more ap- 

 proximate, inserted at a wider angle, and therefore have the spathes 

 shorter and less distinctly infundibul il'onn. 



In Loner's (female) specimen the sheathed stem is 3 cm in diameter; 

 the leaf-sheaths are strongly gihhous above, and densely armed with hori- 

 zontal rows of confluent, triangular, laminate, black spines, which have a 

 lighter-colored sharply defined base. An entire leaf has a petiolar pari I ."> 

 cm long, its total length being 1.18 m ; the petiole has prickly margins; the 

 rachis is armed beneath with a line of single claws along the center, and 

 wiih a similar line on each side. The leaflets are numerous, equidistant, 

 almost equally green on both surfaces; the medials 30 to 35 cm long, 

 t(i to 18 mm broad, rather distinctly 3-C08tulate, their mid-costa on the 

 upper surface is smooth, or has a few small spinules near the apex, the 

 side costulae are slender, and also have a few straggling spinules; under- 

 neath the mid-costa is rather closely bristled, and the side nerves are 

 usually naked, but on these also a few setiform spinules may sometimes 

 he observed. The spadix is C (!) meters long (in one specimen), includ- 

 ing the slender, terminal, very minutely and closely clawed cirrus, simply 

 decompound, with a few, very distant, partial inflorescences, exactly as iti 

 the type, but with the spathes more thickly set with prickles, the 

 secondary and tertiary spathes are also set with minute prickles in their 

 upper part; the spikelets are L5 to 18 cm long, very slightly zigzag- 

 sinuous; with up to 15 or 16 flowers on each side; the involucre is 

 slightly capillar; and the areola of the neuter flower is crescent-shaped, 

 with sharp margins. The fruit is wanting.
