Books

Grasses of the Hawaiian ranges (book)
A complete list of all species covered in Grasses of the Hawaiian ranges (Whitney, Hosaka, and Ripperton, 1939) is presented, along with a complete bibliographic citation. This book "describes and illustrates 103 of the most important grasses in Hawaii.... There are many grasses, either recently introduced or slow to become acclimatized, that have not yet established themselves on the ranges; these are not here included. Species that are found outside the general range areas, as in summit bogs, forest reserves, and national parks, are also omitted. Keys to the tribes and genera [are also included." ([adapted] from the book's introduction)
