A monograph of the genus Maackia (subfamily Papilionoideae, Fabaceae).
THE genus Maackia (subfamily Papilionoideae, Fabaceae) comprises small trees and shrubs, and is native to eastern Asia, specifically Korea, China, Russia, Japan, and Taiwan. Morphologically, Maackia appears most closely related to Cladrastis. However, according to molecular data, Maackia is only distantly related to that genus, being more closely allied to a Sophora from the Himalayas, Salweenia, and Euchresta, while Cladrastis is basal to the subfamily. There is no monograph of the genus Maackia, and while individual floras have mentioned the genus, none have included all the species in their treatments. Specimens were obtained on loan from herbaria around the world. Specimens in fruit were analyzed separately from those in flower, because flowers and fruit do not generally occur at the same time on one plant. A total of 77 vegetative characters, 16 pod and seed characters, and 41 floral characters were measured from 207 specimens. Data were analyzed using NTSYS – pc. Fruiting data analyses resolve 10 species: M. amurensis, M. australis, M. buergeri, M. chekiangensis, M. chinensis, M. fauriei, M. floribunda, M. taiwanensis, M. tenuifolia and M. tashiroi. Floral data analysis is ongoing for the Chinese species, while the analysis indicates M. buergeri, M. chinensis, M. fauriei, M. floribunda, M. taiwanensis, and M. tashiroi are distinct species.
