The Flora represented the life work of botanist Jacob Peter Anderson who's aim was to produce a flora encompassing all known vascular plants in the state. Included are keys and descriptions for each family, genus and species; small line-drawings are provided for diagnostic features of many of the plants included in the book. Long out-of-print and now somewhat dated in terms of what is now known of the Alaskan flora and species taxonomy, Anderson's Flora remains, however, a valuable resource for the study of Alaska's diverse plant life. Also, there is no field guide-sized reference useful for researchers, students, and others studying plants in the field. As the original book did not provide keys and descriptions to the important willow ( Salix ) genus, an addendum is provided with summer and winter keys to the willow species known from the Alaska interior. Author J. P. Anderson (1874-1953) resided in Alaska from 1913-1940, before leaving for a position at Iowa State University where he continued his work of preparing his Flora, including a number of return visits to Alaska for additional field research.
