Ceanothus diversifolius occurs in the North Coast Ranges and the western slopes of the Cascade Range and the Sierra Nevada; it often forms mats to two meters wide. Marginal teeth on young leaves are notable in having more or less persistent, narrowly conic glands, not seen elsewhere in Ceanothus.

Ceanothus cyaneus is known in the flora area only from San Diego County, and is threatened throughout its range. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
