Abronia arcnaria Menz.; Hook, Exot. FL 3: pl. 193. 1827. 
This is easily distinguished by its vellow flowers and orbicular 
leaves. The species is variable in several respects; the Oregon 
and Washington plants have broader leaves and thicker petioles 
than those from California; their fruit has wider wings, which 
are more often truncate above; and their bracts are frequently 
much wider than those of southern specimens. Heller’s 8948 — Fic. 49.— Fruit 
from Westport, Wash., is especially worthy of notice in these of Abronia lat- 
respects. ifolia. Seale. 
This species ranges from Victoria, British Columbia, southward along the 
Pacific coast to Santa Barbara County, Cal. (Carpenteria ). 
®, Abronia maritima Nutt.; 8. Wats. in Brewer & Wats. Bot. Cal. 2: 4. 1880, 
FiGuRE 50. 
This species exhibits but little variation, and that mostly in the size of the 
fruit and the texture of the wings. 
Ranges along the Pacific coast from Los Angeles County, 
Cal, southward through Lower California to the Territorio 
de Tepic, Mexico; also found on many of the islands off the 
southern Californian and Lower Californian coasts.
