3062 Leaflets of Philippine Botany [Vol. vm, Art. 120 



spines, while the sides are flattish, further up the rachis 

 is convex above or has the salient angle obtuse and 

 never sharp, not even so toward the end; beneath in the 

 upper portion it is armed with robust claws, at first 

 solitary, then confluent in groups of 2 to 5; the cirrus 

 is very robust, about 1.5 in. long, very powerfully and 

 regularly armed with half or three quarter whorls of 

 very stout claws. Leaflets numerous, the intermediate 

 leaflets 38 to 40 cm. long, 3.5 to 4 cm. broad, subequidistant, 

 5 to 8 cm. apart on each side of the rachis, elongate to 

 lanceolate, tapering from above the middle to a rather 

 acute base, toward the distal end gradually long acuminate 

 to subulate and with quite bristleless tip; they are firmly 

 papyraceous, green and quite glabrous and spineless on 

 both surfaces, shining above, dull and very slightly 

 paler on the nether side; the midcosta is very slender and 

 somewhat stronger than the 2 or 3 pairs of lateral nerves, 

 the latter only a trifle more conspicuous than the sec- 

 ondary intermediary ones, transverse veinlets numerous, 

 very sharp and much interrupted, margins quite smooth. 

 Female spadix shorter than the leaves, robust, rigid, 

 it forms a diffuse and large panicle about 1.5 m. 

 long or longer, nonflagelliferous at the apex, ending in 

 a very short caudiculum; it is composed of several grad- 

 ually diminishing spike bearing partial inflorescences 

 and is borne on a short peduncular stalk; peduncle 15 

 cm. long, smooth, flattened, acutely 2-edged, 2 cm. broad; 

 primary spathes coriaceous, tubular, very slightly enlarged 

 above, yet very closely sheathing throughout, acutely 2- 

 edged on the axial side in the lower part, only prickly 

 near the mouths which are truncate and produced at 

 one side into a triangular dorsal pri«-kly and keeled point; 

 partial inflorescences inserted just at the orifices of their 

 respective spathes; the lower partial inflorescences some- 

 what reduces in length and number of spikelets; secondary 

 spathes more or less 3 cm. long, very narrowly infun- 

 dibuliform, smooth, truncate at their mouths and produced 

 above on one side into a broadly triangular point; 

 spikelets thickest and inserted just at the mouths of their 

 respective spathels; the lower and larger spikelets 8 to 

 10 cm long, with 8 or 9 pairs of flowers on each side, 

 the others gradually shorter and with fewer pairs of 

 flowers; spathels infundibuliform, truncate, 6 to 7 mm wide 

 at their mouths, produced on one side into a short but broad 

 triangular point, involucrophorum inserted just at the 

 mouths of their respective spathels, very short and scale- 

 like or bracteiform, shortly bidentate and 2-keeled on
