438 PHANEROGAMOUS PLANTS. 



6. EUROTIA, Adam. 



1. Eurotia ceratoides, C. A. Meyer. 



Hab. On the. Walla-Walla River, and through the interior of 

 Oregon, &c. 



7. CORISPERMUM, Linn. 



1. Corispermum hyssopifolium, Linn. 



Hab. On the Walla-Walla River, Oregon, and through the inte- 

 rior. — Variable in the form and length of the bracts, as well as in the 

 inflorescence. 



8. SALICORNIA, Toum. 



1. Salicornia ambigua, Michx. 



Hab. Shores of the Bay of San Francisco, and at Nisqually, Wash- 

 ington Territory. — We have not the means of comparing our plant 

 with S, radicans of Europe. It is certainly the same as Hooker's 

 Salicornia radicans, of which we have authentic specimens collected 

 at the Straits of De Fuca by Dr. Scolder. It is common on the 

 Atlantic coast of the United States, from Maine to Florida, and it 

 always seems to keep distinct from S. herbacea. 



9. S U M D A, Forsk. 

 1. Su^eda maritima, Dumort. 



Hab. Saline soil on the Lower Sacramento, California. [No an- 

 nual species is otherwise known from this region, and the specimens, 

 unfortunately, are not preserved in the Torrey herbarium.]
