Generic criteria and an infrageneric system for Hedysarum and related genera (Papilionoideae-Leguminosae)
Abstract:New generic delimitations for Corethrodendron, Hedysarum, Sulla and Taverniera are proposed together with new infrageneric systems for Hedysarum, with special reference to morphological evidence. Hedysarum sect. Spinosissima is treated as a distinct genus Sulla, and H. sect. Hedysarum is newly circumscribed on the basis of its conserved type, H. alpinum. Hedysarum sections Crinifera, Multicaulia and Subacaulia are very similar to each other and are merged into an enlarged H. section Multicaulia. Hedysarum sect. Fruticosa is transferred to the genus Corethrodendron. On the other hand, Stracheya is reduced to a section of the genus Hedysarum. A key to the genera and the infrageneric taxa, their nomenclature, synonymy and short descriptions are provided.
