Arnold, H.L.: Poisonous plants of Hawaii. 71 pp., 24 illustr. cloth. Sh. 23/6, DM 11.99. This book contains more than 90 varieties of plants growing in Hawaii which in 1931 were deemed toxic in some way. Many of these are injurious only to animals, like the leaves of the haole koa; or are harmful only to those very susceptible individuals, like the milk from the plumeria; or are nearly negligible, like the avocado or alligator pear, whose pit is only very slightly if all toxic to rodents and probably not to other mammals.
