than in Chrysopsis—a character quite like that which, in the 

 main, distinguishes such thoroughly acceptable genera as 

 Aster and Erigeron. So that, upon the whole, we, who have 

 to deal with the North American allies of Hysterionica, 

 seem at present fully warranted in maintaining Chryso'psis, 

 though under just what limitations may not be so dear; for, 

 if we receive the genus upon its character of a double pap- 

 pus, as Asa Gray did, then we must exclude Ammodia, or 

 else be as inconsistent as that author was. But, in view of 

 the general impracticability of resting asteroid genera on 

 matters of a simple or double pappus, I here ignore the 

 character and admit the species of Ammodia into Chrysopsis, 

 on the ground of their general likeness to the species of that 

 genus. However, I cannot but remark that so great is the 

 difference in fades between the type of Ammodia and 

 Chrysopsis Breweri, that I feel less hesitancy about allowing 

 them both to figure as species of the ample genus Chrysop- 

 sis, than I should in attempting to force them into a genus 

 'Ammodia of two or three species, where the contrast 

 between Breweri and the others would seem to stand out 

 more glaringly. Eeally, the foliage and the inflorescence of 

 G. Breweri are not those of any Chrysopsis or Ammodia; 

 and perhaps the most satisfactory course to pursue would be 

 to adopt ^wmodfa with its two species {A. Oregana, Nutt.,

ADDITIONS TO THE FLORA OF LOS ANGELES 



COUNTY AND CATALINA ISLAND.— I. 



By Alfred James McClatohie. 



Los Angeles County, like so many other counties of Cali- 

 fornia, has a very much diversified surface, and consequently 

 a varied flora. From the sea coast on the southwest it 

 extends over the San Gabriel Mountains into the Mojave 

 Desert on the northeast. Notwithstandinc: the extensive col-
