viscid substance, which causes particles of fine black sand to 

 adhere to the branches and leaves.

 nana ; ramis brevissimis dense foliatis, foliis omnibus triden- 

 tatis carnosis. S. Chili; Captain lieynolds. — The capitula 

 are alike in both these varieties ; our /3 may, perhaps, form a 

 distinct species. Our a. is closely allied to S. Chilensis, and 

 may possibly be a state of it with trifid leaves,

 Summit of the Cumbre, and Paramillo delas Cuevas, Andes of 

 Mendoza; Dr Gillies. — Our specimens of this plant are very 

 imperfect ; we are even doubtful if the capitula be not dis- 

 coid rather than radiate, and if the stems be not herbaceous; 

 but the leaves are very peculiar, and about an inch long.
