In 'Ferns of Hawaii National Park' by Douglass H. Hubbard, the author provides a comprehensive guide to the various species of ferns found within the lush landscapes of Hawaii National Park. Hubbard's meticulous attention to detail and in-depth descriptions of each fern species make this book an essential resource for botanists, nature enthusiasts, and horticulturalists alike. Written in a clear and accessible style, the book not only serves as a guidebook but also as a rich source of information on the ecological importance and cultural significance of ferns in the Hawaiian ecosystem. The book's beautiful illustrations and captivating narratives bring to life the enchanting world of ferns in this tropical paradise. Drawing from his years of experience studying ferns in Hawaii, Hubbard's expertise shines through in this scholarly work. His passion for botany and dedication to exploring the natural wonders of Hawaii are evident in every page of this book. I highly recommend 'Ferns of Hawaii National Park' to anyone seeking to deepen their understanding of ferns and their place in the Hawaiian landscape.

He includes information from Hawaiian folklore and mythology, describes uses of ferns by native Hawaiians, and updates Hawaiian common names. More than one hundred line drawings illustrate all 222 species, varieties, and forms, and some hybrids." "This well-researched and highly readable book will be enthusiastically received by amateur and professional naturalists, fern enthusiasts, and professional botanists."--BOOK JACKET.

"The most abundant ferns growing beneath the larger tree ferns are AMAUMAU (40) and the AMAU (41). Found frequently in both the Kilauea and Haleakala sections of the Park, the amaumau is usually larger than the less common amau and the fronds are not as hairy. The easiest method of identification, however, is by comparing the undersides of the frond segments (see illustration). The amaumau is smooth while the amau is prominently veined. Usually smaller than the true tree ferns, and known only from the Hawaiian Islands, ferns of this genus may reach heights as great as 12 feet. A comparison of the photographs of these ferns with the tree ferns will show that the entire frond of the AMAU or AMAUMAU resembles a single segment of the many-branched frond of the tree fern."
