HERBERTIA, the year-book of the American Amaryllis Society, has now reached its tenth volume (from L. S. Hannibal, Concord, California, July 1944). This publication maintains its potent blend of science with practice. It employs fertility in number of its titles with economical expression in its individual papers, to achieve a wide review of all questions which affect the horticulture of Amaryllids. Many facets are discussed—personal, historical, and cultural. In the sections on classification, genetics, the physiology of reproduction, and pathology, several interesting facts appear.
