The California Academy of Sciences's (CAS) Botany Department hosts this interesting and beautiful site on California's wildflowers. Spectacular color photographs of over 125 species of wildflowers serve as illustrations to this electronic field guide. Users may browse species by flower color (white through brown), common name (Alpine Lily to Yerba Mansa), latin name (Achillea millefolium to Zigadenus fremontii), or family name (Alismataceae through Violaceae). Additionally, floristic regions are provided in a color-coded map of California. For each species, the taxonomic identity (common, Latin, and family names), a description, photographs, and distribution information are provided. Educators and students of botany will find this site particularly useful; others will want to go see California in bloom.
