230 TRlANDRlA MONOGYNIA, SctrpuS. 



that species is described by Vahl as having three stamina : (see 

 Fimbristijlis dkhotoma, Enum. ii. p. 287,) consequently they must 

 be different* 



38. S. astivalis. Retz. Obs. iv. 12. 



Spikes rounded, subsquarrose ; involucre six-leaved, longer than 

 the compound umbel ; scales monandrous. Fahl. Enum. ii. 288. 

 (tinder Fimbristj/lis.) 



I received this elegant little grass from Nepala where it grows in 

 low fields during the rainy season. 



Obs. My specimens agree perfectly with the descriptions quoted 

 above. They are three inches high ; spikes oblong, obtuse, mea- 

 suring about three lines in length, with villous scales which end in 

 a long, recurved, scabrous awn as in S. squarrosus. Ovarium len- 

 ticular, obovate, smooth, shining, pearl-coloured, covered almost to 

 its base with numerous loosely adhering, vvl ite, flat fascicles of villi, 

 which proceed like rays from the enlarged base of the smooth, bifid 

 style, and serve to keep ttie latter attached to the seed. This is a 

 second instance of a singular structure, observed by the immortal au- 

 thor of the Prodromus florae novse hoUandiae, in another species of 

 Funbristylis, (vol. i. p. 225). — N. W. 



39. S. diphyllus. Linn. Sp. PL ed. Willd. i. 30;. 



Culms erect, from one to two feet high, semi-culumnar. Umbel 

 decompound; scales obtuse, diandrous. 8eeds roundish, obcordate, 

 smooth. 



Fimbristylis diphylla. Vahl. Enum. ii, 249. 



Delights in a rich wet soil. 



Hoot fibrous. — Culms erect, seven-eighths naked, from one to two 

 feet high, sometimes a little compressed. — Leaves chiefly radical, 

 half the length of the culm, rigid.— Umbel terminal, decompound. 

 — Involucre two or four-leaved, the larger about the length of the um- 



* 1 have received specimens of this grass, which undoubtedly is a Fimbristylis, 

 from Nepala; itis intermediate between F. dichotoma and glauca, Vahl, differing from 

 both in being monandrous.— N. W.
