vagina with a short broad membranaceous ligula at the moutli. Corymbs 

 compound, ckistered into a short and broad panicle with numerous spiculte ; 

 radii several, umbellate, patent ; 2nd radii subumbellato-facemosely disposed, 

 patent, with a cluster of spicul^B towards the apex; the terminal one about 

 10cm. across; the lateral ones alike as 2nd radii of the terminal one, with 

 a erect peduncle arising from the' superior axils and lower down the culm; 

 involucral-bracts leafy, longer than the panicle, attaining about 17 cm. long 

 and 7 mm. broad ; bracts and bracteoles setaceous. Bpicula3 erect and erect- 

 patent and patulous, narrowly lanceolate, acuminate, ferrugineo-brimneus, 

 9-10 mm. long, with 1 perfect flower and 1 or 2 males. Empty glumes 

 4, subulato-ovate ; flowering ones longer, ovate but the superior ones ovato- 

 lanceolate to lanceolate. Setfe 6, antrorsely scabrous, longer than the 

 achene but lower than the rostrum of the achene. Stamens 3 ; filament 

 long, low^er than the rostrum of the mature achene. Achene oblong-obovate, 

 ferrugineo-bay, compressed, with a few pits, transversely rugulose, 3J mm. 

 long ; rostrum slenderly subulato-conical, gradually attenuated above, dilated 

 and as broad as the achene at the base, calyptrately crowned with free 

 margin on the achene, longer than the achene, broadly and shallowly 

 furrowed on both faces, 5 J mm. long ; style long, 17 mm. long, very shortly

 tinued, the lower ones distant and peduncled, the peduncle erect and rather 

 short ; bracts setaceous. Spicul?3 erect, lanceolate, subulate, acuminate, 

 3-4-flowered, 5-Q mm. long, ferrngineo-brunneus. Empty glumes 3, el- 

 liptical-ovate ; flowering ones oblong-ovate. Setfe 6, smooth, longer than 

 the achene but lower than the rostrum. Stamens 3 ; filament exceeding 

 the rostrum at the mature achene. Achene oblong-obovate, 2 mm. long, 

 flavescent-subbrunneus, transversely rugulose; rostrum as long as the achene^
