In general appearance the present plant so closely resembles N. Gaudichaudii, that at first sight it is difficult 

 to distinguish them. Cassini describes the flowers as apparently yellow ; but Mr. Anderson, who collected the 

 plant during Capt. King's voyage, mentions that they are white. The genus Triachne, remarks De Candolle, 

 hardly differs from Nassauvia, nor can I find any character by which to separate them.

A very distinct species, also found at Port Desire by Mr. Darwin. The woody group of Nassauvia, to 

 which the present plant belongs, is nearly peculiar to South America, and to the drier parts of that continent, 

 especially of South Chili and Patagonia ; they do not cross the Strait of Magalhaens on the western side, but on 

 the east a few stretch down to Port Gregory, Staten Land, and the Falkland Islands. I have appended the 

 description of an allied Patagonian plant, which forms a new genus.*

I have seen only one specimen of this species, gathered by Capt. King ; it is very distinct from its congeners.
