Vascular Plants
From Natural History of Southeast Alaska
This list was compiled from primarily my own observations, range maps in Hulten's Flora of Alaska and Neighboring Territories, and Hall's Native Plants of Southeast Alaska. Additionally, when available, range maps in the Flora of North America were consulted. Choices of scientific name primarily follow the Flora of North America, though there are occasional deviations. I also relied on the USDA PLANTS Database for names. Disagreements were typically decided in favor of the Flora of North America.
