Introduction to the Vascular Plant List, Oakmead Herbarium
Web Version with Photo Links
Jasper Ridge Biological Preserve, Stanford University
Scientific names follow TJM2 and supplements; we also include plants and names not treated by TJM2 and supplements. Following the Marin Flora, 2nd ed, 2007: “We include here as naturalized species those that are established and have a true competitive status without cultivation whether the plant is aggressively spreading or seems only passively and locally established. . . . Experience has shown that the waifs of today may become the weeds of tomorrow.”
Abbreviations & Symbols
Documentation Type and Plant Status:
SPEC—Specimen, at the Jasper Ridge herbarium (JROH). Plant is presumed present unless otherwise noted.
spec—Specimen but no documentation post-1993 (recent 25 years of herbarium team surveys).
SPEC$—Specimen, at herbaria other than Jasper Ridge.
DOC—Documented, plant observed and/or photographed by herbarium team but not vouchered.
REP—Reported, usually by more than one observer with detailed location information. No known specimen; unconfirmed by herbarium team.
rep — No documentation post-1993 (recent 25 years of herbarium team surveys).
Rare, Naturalized, Waif, Hybrid, etc.:
* non-native species naturalized in California
! California native species not native to the Preserve or surrounding area
N—persistent at JRBP and not mentioned or mentioned and not given taxonomic status in TJM2
W—persisitent, sometimes reproducing at JRBP and considered a waif in our bioregion according to TJM2. Waif designates a taxon occurring as a garden escape, agricultural weed, or non-native species that does not become naturalized in our region, but may be naturalized in other parts of California
Misc. Abbreviations and Acronyms:
cf.—compare. The specimen does not exactly match the species and/or a key element (e.g., fruit) is lacking.
