Often on coastal sands, but not confined to these. Widely dispersed 

 in Central Europe, from Holland and France to far into Central Asia, 

 and in ISTortli America, from Atlantic coast to California, -nhere it is 

 chiefly found in the mountains. Also in Africa. 



Sclioenus nitens Hook. f. 



Perennial, slender stem from creeping rhizome, 15 — 30 cm. high; 

 leaves few at base, short, terete, but furrowed along inner side, sheaths 

 not bearded. 



Marine coasts of Australia, from iloreton Bay to Western Australia, 

 usually in clayey soil, but also frequently in sand. Also in Tasmania, 

 Xew Zealand, and estratropical South America.

Perennial grass, with creeping, scaly rootstock, stems erect, stout, 

 4 — 12 dm. high, leaf-blades long, flat, smooth, tapering from about 

 1 cm. wide near the middle to long, slender points; edges rolled inward

Sea coasts of Europe, from Xorth Sea to Mediterranean, Xorth 

 America, along the Atlantic coast and in a few places on the Pacific. 



Spinifex liirswtvLS Lab. 



Stout stems; creeping, forming large tufts; leaves often over 3 dm. 

 long, margins involute, woolly; the male plant has sessile spikes in a 

 terminal head, each spike about 5 cm.long.spikelets sessile in the spike, 

 15 — 20 mm. long: the female plant has numerous spikelets in large 

 globular head, the spikelet 20 — 25 mm. long, acute. 



On sandy shores of Xew Zealand, Xew Caledonia, Tasmania, and 

 Australia, from Queensland to West Australia. 



A slightly differing form, occurring near Fremantle in Western 

 Australia, has been referred to as S. longifolius E. Br., but its right as 

 a distinct species is doubtful. 



S. squarrosus L. 



Eesembles foregoing species in habit. The heads are large, radiating, 

 and when the seeds are matured, the heads become detached, and are 

 easily carried by the wind along the sand, thus dispersing their seeds. 



On sandy shores of India.
