478 OBSERVATIONS ON PLANTS. 



Triodia procera, R. Brown. 



Desert on the tablelands at Prince Regent's River. Mentioned 

 by the travellers as the resinous Spinifex and as a fibre-plant. 



Gleichenia platyzoma, Rv.M. 

 Upper Drysdale and Forrest Rivers. 



Cheilanthes tenuifolia, Swartz. 

 Prince Regent's River. 



This is the widest distributed fern in Australia; to judge from 

 its frequency it could be naturalised with ease in mild regions 

 elsewhere. 



Cheilanthes vellea, F.v.M. 



Carson River. 



Mr. Bradshaw saw also a Lygodium entwining to a considerable 

 height some trees.
