CHENOPODIACEiE. 439 



2. Su^ida fruticosa, For ah. 



Hab. Shores of San Francisco Bay. — A stout, densely-leaved form, 

 of which we have specimens from Chihuahua and other parts of 

 Mexico. A more slender variety, with shorter and narrower leaves, 

 occurs on the Lower Sacramento. This, as the seeds are much more 

 commonly horizontal than vertical, may be S. dendroides, Moq. 

 Chenop., which, again, is probably not distinct from S. fruticosa. 

 [The shrubby Suceda of the Bay of San Francisco is now determined 

 by S. Watson to be distinct, both from the foreign S. fruticosa, and 

 from the Mexican plant referred to.]

Hab. Interior of Oregon and Washington Territory. — It is re- 

 markable that this well-characterized Chenopodiaceous plant (which 

 is the Pulpy Thorn of Lewis & Clark), should have been doubtfully 

 referred by Nees to Urticacece, and a suspicion expressed by that acute 

 botanist that it might belong to Euphorbiacece. The female flowers 

 are often overlooked, being very small, and partly concealed in the 

 axils of the leaves.
