This is a checklist of the vascular plants of Mission Trails Regional Park. We list only those taxa that are documented, as only they can be scientifically verified. We consider documentation to primarily be vouchered herbarium specimens. These are cited and linked to specimens databased through the CCH2: Consortium of California Herbaria 2. We use the Jepson eFlora as the primary source of our taxonomy, but in some cases use the primary literature from more recent studies.
