ADDlTioxs To THE FLORA OF LOS ANGELES 

 COUNTY 



By AxsTRuTiiER D.wiDSON, C. M., M. D. 



'T^HE season just closed may be credited with a comparatively 

 -^ large number of additions to our catalogue of the local 

 flora. 



The most important additions have been made by Mr. P. C. 

 Standley of Washington, in the volume of the Flora of N. 

 America, devoted to the Chenopodiaceae. The confusion pre- 

 vailing in the nomenclature has been rectified and in the process 

 quite a large number of species have been described as new, of 

 which about half a dozen are found in Los Angeles and Orange 

 Counties. 



Besides those the following have been added to the list by 

 the members of the Botanical section. 



Phalaris paradoxa praemorsa C. & D. Common on La Brea 

 Rancho. 



Agrostis alba L. Ditches at Alhambra. 



Lepidium draba L. Huntington Beach ; threatening to be- 

 come a weed. 



Loefflingia squarrosa Nutt. Roadsides at Crescenta. 



Arenaria Nuttallii of the Catalogue is the var. gracilis Rob- 

 inson. 



Castanopsis chrysophylla A. DC. The Western Chinqua- 

 pin, ]\Its. Antonio and Islip. 



Li the description of Draba vestita Davidson (Bull. S. Cal. 

 Acad., \'ol. 15, page 17), I omitted to state that the strap-shaped 

 petals are bluntly toothed at the apex, each narrow petal show- 

 ing a tooth and a half.
