This elegant plant grows indiscriminately on the dome, 

 the face of the table-land, and the plain. It extends to 

 the length of several fathoms, decaying from the base in 

 proportion as it advances, and drawing sustenance by the 

 radicles which it pushes from time to time into the soil. It 

 is entirely clothed witli leaves ending in a white filament, 

 which gives it in its fresh state a silky feel. The shoots are 

 numerous and irregularly subdivided. The spikes sessile, 

 cylindrical, two inches long, simple, bifid, or in pairs, 

 equal in thickness to the shoot, and of a yellowish colour. 

 The floral leaves are reflected after the dispersion of the 

 seeds.
