This comprehensive flora, the first of the area, is designed for use by both the serious beginner and the trained botanist.

The flora is illustrated by 250 line drawing and ten photographs. In addition, ... Read morethere is a map of the Santa Cruz Mountains area and a stratigraphic profile of the rock formations.
