Santa Monica Mountains
Flora: A Checklist of the Vascular Plants

Bob Muns, 1983, revised 1999, updated in 2002

This is a working list, about which we make no guarantees until we finish checking
it. The information below is incomplete, and there may be errors we haven't caught yet.

This nucleus of this webpage is Bob's printed booklet dated 1999. Updates include:

• additions from individual floras: those in the Santa Monica Mountains and the Santa Monica Mountain area of the South Coast.
• additions from a plant walk at Malibu Creek State Park by Jane Strong in 2002
• addition of subspecies information from the Santa Monica Mountains Flora of Raven et al.

The origin of the updates is encoded in Regional Flora of Santa Monica Mountains.

Note that this flora does not include any taxa unidentified for species, nor any taxa which only occurred as plantings. Such taxa are noted in the subregional floras.
