Geog. note.— Eubus vitifolius is common in the lowlands of the delta region of the Sacra- 

 mento and San Joaquin rivers, and thence follows the moist banks or creek bottoms mto the 

 foothills. Throughout the Eedwood belt it is found in thickets on the borders of groves or of 

 clumps. On the coastal hills facing the sea it often forms very dense tangles in association with 

 Ehus diversiloba, Diplacus aurantiacus, Corylus rostrata, Heracleum lanatum and Artemisia
