About this book

**Uploader's comment:** A highly technical, exhaustive and authoritative flora of the Hawaiian Islands from the mid-twentieth century. The author, Otto Degener, was considered the most eminent expert in this field. Obtusely scientific, but also masterful. Suited for very in depth study of particular Hawaiian plants. It is strictly a flora: while it does have some good introductory material, it exclusively focuses on the botanical identification of the flora. **Encyclopedia excerpt:** Otto Degener, a renowned botanist and conservationist, was a leading expert on Hawaiian flora. He not only documented the islands' plant life in his groundbreaking work, Flora Hawaiiensis (1932), but also raised awareness about conserving native habitats threatened by invasive species and rampant development. In 1932, Degener started the first book on Hawaiian plants published since that of William Hillebrand in 1888. It was titled Flora Hawaiiensis, and published in several volumes over his lifetime. On January 10, 1953, he married the botanist Isa Irmgard Hansen, whom he met in Berlin in 1952. They collected plants together in the Hawaiian archipelago. After 1956 Isa Degener was a coauthor for Flora Hawaiiensis. Amy B. H. Greenwell assisted in some of the volumes, and left her property as a botanical garden.H e collected over 36,000 different species and preserved some 900 threatened and endangered plants. His specimens were left to the New York Botanical Garden.
