Stems' 1 ft., connected at base on a very short slender lignescent rhizome 

 L-eaves with scattered slender needle-white hairs or glabrescent, tip lanceolate sub- 

 obtuse (not setaceous-caudate). Spikelets small, as of . tesseVata. Nut scarcely 

 -^ in, in diam., dried young reticulate, mature osseous smooth or nearly so. Disc- 

 margin coloured, glandulose, not (or obscurely) 3-lobed. S. laxa, R. Br., hardly 

 differs but by its strictly fibrous roots. 



10. S. flaccida, G. B. Clarke (non Steud.} ; slender, softly bairy all 

 over, roots fibrous, panicles axillary small distant, fern, glumes hairy, style 

 3-fid, nut small ovoid smooth white, disc-margin subentire coloured 

 glandular.

Stems flaccid, 1-2 ft. Leaves in. broad, lanceolate, subobtuse at tip. Panicles 

 axillary, % in. 'long. Spikelets small, all unisexual, fern. |- in. long usually con- 

 taining the depauperated sterile apex of the spikelet as a lateral compressed rudiment 

 \of two glumes) about ^ length of nut. Nut broad, obtuse not apiculate. Might 

 stand as a var. of the Australian S. rugosa, Br., which however has a reticu ated 

 subtuberculated nut. 



*** Nut smooth, white, fluted longitudinally.

 nearly smooth and glabrous, panicle of several remote small axillary 

 clusters, fern, glume sub-3-toot.bed, style 3-fid, nut very small, disc-margin.

Roots fibrous, slender. Stems 1-12 in., tufted. Leaves 2 by - i in., lanceolate, 

 tip subobtuse ; sheaths trigonous, not winged. Primary bracts (floral leaves) alto- 

 gether leaf-like tuft usuallv of very small subsessile clusters just exserted from their 

 sheaths, but in evolute examples, lower clusters are sometimes paniculate with 

 branches 1 in. long. Spikelets all unisexual, fern. ^ j n . long with 1 or 2 smaller 

 male spikelets closely applied to its base. Fern, spikelet : lowest glume ovate boat- 

 shaped obtuse ; 2nd glume (sterile) rather longer, boat-shaped, apex deeply emar- 

 giuate (from the centre of the emargination the midrib is produced as a linear- 

 triangular point), smooth, 2-ribbed on each side ; 3rd glume similar to 2nd and 

 subopposite to it, containing fern, flower ; no rudiment of an upper glume. Nut 

 scarcely -$ in. in diam. ; disc small obpyramidal, margin most minute, white, 

 truncate. See Goebel in Ann. Jard. Buit. vii. 132, t. 15, figs. 21-29, who considers 

 the female flower truly terminal, and therefore places the species among the 

 American Cryptaitgiea.
