Official list:

Updated to include some taxa that were missing from the official site (February 2013). Also includes some additional symbols that tie commonly used subspecies to species used for delineation purposes. For example the symbol: ALINT (Alnus incana ssp tenuifolia) will link to ALIN2 (Alnus incana). List includes USDA PLANTS symbol, scientific name, author, common name, and indicator status for Alaska. For the four taxon that are regionalized for south central (Interior Alaska Lowlands) those statuses were used (ANPO is listed as OBL, BEPA as FAC, CACA11 as FAC, and RUAR6 as FACU).
