Advances in Legume Systematics 14. Classification of Caesalpinioideae. Part 2: Higher-level classification. 2024. (Special edition PhytoKeys 240). illus. 552 p. gr8vo. Paper bd.

This Special Issue of PhytoKeys presents a new higher-level classification for subfamily Caesalpinioideae (Leguminosae). With ca. 4680 species and 163 genera, Caesalpinioideae is the second largest subfamily of legumes. It is a globally distributed, ecologically and economically important group.
This taxonomic compendium, produced by 48 authors, includes a key to genera and an illustrated glossary for specialised morphological terms. Taxonomic and nomenclatural information, morphological descriptions and notes are given for each genus, tribe and named clade. For each genus, the diversity of growth forms, foliage, flowers and fruits is illustrated, and a distribution map, based on quality-controlled herbarium specimen localities, is provided. This classification of Caesalpinioideae provides the necessary framework for downstream analyses of biogeography, trait evolution and diversification, as well as for taxonomic revision of still understudied genera.
