This species was sorted from L. argentea (the white-headed) by its deep purple- 
spotted (sphacelate) heads; but the character is not a safe one any more than the 
number of spikelets (¢viceps). The length of the style draws a strong line between the 
two; L. triceps differs little from L. filiformis except in being more robust. 
4. L. prieuriana, Steud. Syn. Pl. Glum. ii. 130. Glumes broadly 
obovate, very obtuse. Lower hyaline scale ovate, almost orbicular, 5- 
nerved. Nut obovoid-globose ; otherwise as LZ. triceps.—C. B. Clarke

Glabrous. Stolons slender, clothed by small ovate-lanceolate scales. 
Stems 8~16 in. long, slender. Leaves 2-8 in. long, linear. Head of 
‘1 spikelets ; bracts 3-2, spreading, lowest 2 in. long, linear. Spike- 
lets } by 4 in., ovoid, white or cinnamon-coloured, dense, appearing 
hispid from the suberect points of the glumes. Glumes oblong-obovate 
suddenly acuminated into a linear tip 3 the length of the glume. 
Hyaline scales nearly as long as the glume (without its tip); the lower 
quadrate-elliptic, 7-nerved ; the upper elliptic, 3-nerved. Stamens Py 
Nut 3 the length of the hyaline scale, oblong-obovoid, unequally trigon- 
ous, brown-black, smooth. Style more than } the length of the nut, 
linear ; branches 3, linear, exserted.—C. B. Clarke in Durand & Schinz,
