Originally published in 1976, Professor Corner's study is a major work of botanical scholarship and reference. In these two volumes the author shows how important the seed is in classification. Systems of ordinal classification based on the flower are potentially misleading in as much as floral similarity is often the effect of polyphyletic convergence. A different system of classification based on the seed is outlined.
The work is the result of more than thirty years' collection and study of seeds, particularly in the tropics. The text in the first volume has five introductory chapters leading up to the arillate seed. There then follows in alphabetical order concise descriptions of the seed in families and certain of their genera. The second volume contains more than 600 original illustrations made by the author. The two volumes are unique sources of teaching and reference material for botanical institutions throughout the world.
