Said by Dr. Hooker (Flor. Antarct. ii. p. 521) to be " very 

 abundant on rocks from 100 to 1200 feet of elevation — by far the 

 most handsome vegetable production of Kerguelen's Land." 

 From all states of the preceding, from which it is easily recog- 

 nized, it appears to be sufficiently distinct.
