There are smaller leaves mixed with the larger ones in this 
plant, which I should be disposed to consider as stipules, if they 
were placed with any sort of regularity. Asa species it is very re- 
markable, coming nearer than any other to J. setiformis, Brit. 
Jung. (TaB.XX.) in the quadrifid division of the leaf. Its colour 
is peculiarly black, except at the apices which are yellow-green,
