Checklist of the Vascular Flora of Santa Rosa Island

Locality: Santa Rosa Island, Channel Islands National Park
Abstract: This is a voucher-based checklist of Santa Rosa Island, one of the California Channel Islands off the coast of California. Data for the checklist came from study of specimens deposited in herbaria. All information was cross-referenced against Wallace (1985), and Ratay et al. (2014), along with the latest taxonomic treatments in regional floras (e.g., The Jepson eFlora, https://ucjeps.berkeley.edu/eflora/). In some cases, taxonomic experts were consulted to assist with determinations. This list will be continually updated.
