Key to families | Table of families and genera This text currently parallels The Jepson Manual: Vascular Plants of California, Second Edition that is now available at the University of California Press. Text appearing in blue on this page will not appear in the printed book; it will be displayed only on the Web. Specimen numbers are hyperlinked to records in the Consortium of California Herbaria data view where possible. Taxa are hyperlinked to entries in the Jepson Interchange via the "[Online Interchange]" link. |
