The names and definitions of the different kinds of fruits have primarily appeared in botanical textbooks, without references. This new treatment includes a key to 95 fruit types, a systematic review of their names and definitions, and an index to carpological terms. The concept "fruit" and the terminology descriptive of fruit morphology are defined to distinguish the different kinds (types). Some of the advantages and disadvantges to previous classifications of fruit types are discussed; the criteria considered to be the most useful are adopted here for a new systematic treatment. The volume includes many helpful black and white illustrations of fruit types.
