11. A ACICULATUS, Retz. Obs. v, 22. Culms erect, rooting 

 at the base, simple or branched, 1 to 2 feet high ; nodes, sheaths, and 

 leaves smooth, the last subradical and abbreviated, 1 to 3 inches long 

 2 to 3 lines broad, lanceolate ; margins rough and prickly; panicle 

 terminal, linear-oblong;, 1 to 3 inches high ; branches sub-verticell- 

 ed, simple, hirsute towards the top with short hairs ; glumes of 

 the hermaphrodite floret subequal, the lower acuminated, upper 

 bifid, dentate, with the awn about twice the length of the floret. 

 The seeds of this species are exceedingly troublesome to those who 

 walk where it grows ; they stick in the stockings, and produce a 

 disagreeable itching. Syn. Raphis trivialis, Lour. Cochin 676; 

 Centrophorum chinense, Trin. Fund. t. 5 ; Chrysopogon aciculatus, 

 Trin. loc. cit. 



12. A VERTICILLATTS, Roxb. Fl. Ind. i, 263. Root woody, 

 perennial ; culms erect, simple, very leafy, round, smooth ; leaves 

 1 8 inches long and f an inch broad ; margins minutely spinous, 

 hairy on the inside near the base ; panicles erect, conical, lax, 8 to 

 10 inches long, composed of many verticelled, simple, filiform, 

 waved, drooping, 3-flowered branches, as in the preceding ; spike- 

 lets surrounded with much brown hair; inner glume of the herma- 

 phrodite floret awned. 



13. A PETIOLATUS, Dalz. Culms erect, 3 feet high, simple 

 below, dichotomously branched above, semiterete, smooth and 

 shining ; sheaths smooth, keeled, ciliated on the margin ; leaves 

 petioled, broad-lanceolate, very thin and tender, sparingly pilose on 

 both sides, bristle-pointed, 6 to 8 inches long, 1 to I inch broad ; 

 petiole 4 inches long, slender, grooved ; inflorescence whitish, 

 panicled ; panicle branched below, above composed of simple 

 alternate spikes, 1 inch in length ; sessile spikelet with the glumes 

 glabrous, the pedicelled one bearded at the base, and covered with 

 long, white hairs, all 7 to 9-nerved ; paleae of both spikelets furnish- 

 ed with an awn, that of the pedicelled spikelet much larger. A 

 remarkable Grass, the existence of a distinct petiole being extreme- 

 ly unusual in Grasses. There is one something resembling this in 

 Nepal, with a petiole IHnch long, but the inflorescence is purple 

 and smooth, and in other respects different. This has been called 

 A petiolaris by Trinius. 



27. APLUDA, Linn. 



1. A ARISTATA, Linn. Culm rooting at the base, ascending, 

 branched, 2 feet high ; nodes and sheaths smooth ; leaves lanceolate- 

 acute at the base, revolute on the margin, and attenuated into a 

 short petiole, 2 to 6 inches long, 1 to 3 lines broad ; panicle 

 contracted ; involucre of the rays ovate ; involucel lanceolate,
