Most are very difficult to identify without the help of good illustrations. This is designed to be a simple, color photo guide to help you identify some of these plants. This guide is published electronically in Adobe Acrobat® format so that it can easily be updated as additional photographs become available. You have permission to freely download, distribute and print this guide for individual use. Photographs are © 2014 Wilde Legard, all rights reserved. In this guide, the included plants are sorted first by form (Ferns & Fern-like, Grasses & Grass-like, Herbaceous, Woody), then by most common flower color, and finally by similar looking flowers (grouped by genus within each family). Each photograph has the following information, separated by '-': COMMON NAME According to The Jepson Manual: Vascular Plants of California, Second Edition (JM2) and other references (not standardized). (Scientific Name) According to JM2 and eFlora (ucjeps.berkeley.edu/IJM.html). Origin & Longevity Native, Naturalized, or Waif (not reproducing without human care). Annual, Biennial, Perennial, or a combination. Family Name Common family name according to JM2, (Bloom date range) Period during the year when the plant blooms, according to JM2 and other sources. '-' if plant does not bloom (ie. Ferns). Habitat Habitat description according to JM2 and other sources. ID Characteristics Plant description with identification characteristics and other notes, based on multiple sources including: Annotated Checklist of the East Bay Flora, Second Edition (2013), JM2, Plants of the San Francisco Bay Region (Revised Edition), and Weeds of California and Other Western States. Additional notes Occasionally, an additional note may appear (ie. NOXIOUS weed, INVASIVE weed, Fed & Calif. ENDANGERED, etc.).
