Tetranthera californica Hook. & Arn. Bot. Beech. 159. 1833. 
Oreodaphne californica Nees, Syst. Laurin. 463. 1836. 
Type locality: California, probably in the vicinity of San Fran- 
cisco or Monterey. 
Distribution: Valley of the Rogue River, Oregon, southward 
through the Coast Ranges and on the western slope of the Sierra 
Nevada to the mountains of San Diego County. In southern 
California the laurel is frequent in canyons or on shaded slopes 
in the upper part of the chaparral belt and in the lower Transition, 
but is usually reduced to a small tree or arborescent shrub. 
Umbellularia is one of the many genera peculiar to the California 
Sub-area, and is a good example of the uniqueness of the flora.
