This must be very close to L. alhiceps, Ridley, and is possibly a mere form 

 thereof. Tlie examples of Welwitsch's 6784 are too young to form a decided 

 opinion upon. 



7. L. atra, Ridley in Trans. Linn. Soc. ser. 2, Bot. ii. 1G2. 

 Glabrous. Rhizome hardly any. Stems tufted, 4-8 in. long, slender. 

 Leaves J-J the length of the stem, linear. Head of 5-1 spikelets ; 

 bracts 2, lower 1| in. long, linear. Spikelets -J- J by |- in., cylindric, 

 obtuse, black, appearing minutely hispid from the very short glume- 

 tips. Glumes very small, obovate, suddenly acuminated into a lanceo- 

 late-linear tip J the length of the glume, nearly black, the tip a brown- 

 black. Hyaline scales nearly as Mng as the glume (without its tip) ; 

 lower narrowi^^ elliptic ; upper oblong. Nut minute, § the length of 

 the hyaline scale, oblong-eJlipsoid, trigonous, smooth, brown-black. 

 Style less than J the length of the nut, linear ; branches 3, short. —

 V. 650. Glabrous. Rhizome short. Stems approximate, 12-20 in. 

 long, robust for the genus. Leaves ^ the length of the stem, linear, 

 terete, leaf-sheaths brown-red, split down on one side, truncate at top. 

 Head of 5-1 spikelets ; bracts 3-2, lowest up to 2 in. long, spreading, 

 linear. Spikelets J-J^ by J in., dense, cylindric, obtuse, somewhat 

 squarrose, dusky brown-red. Glumes broadly obovate, striate, 

 suddenly narrowed into a lanceolate-linear tip J the length of the glume. 

 Hyaline scales nearly as long as the -glume" (without its tip); lower 

 broadly-elliptic; upper narrowly-elliptic. Nut nearly as long as the
