Revision of the Genus Dunbaria Wight & Arn. (Leguminosae-Papilionoidea)

About this book

Language: English with bilingual summary in English and French

One of the genera of the Phaseoleae subtribe Cajaninae (Leguminosae-Papilionoideae), Dunbaria, has long been incompletely known. In the present revision twenty species are recognized. One species, Dunbaria floresiana, was newly described, and six species had to be provided with a new combination. Several names had to be sunk into synonymy, including some well-known ones, like Dunbaria longeracemosa, which is synonymous to the earlier and poorly known D. bella. Most Dunbaria species have an Asian distribution, some species are found in Australia and on New Guinea. The area extends from 72 to 143 degrees Eastern longitude, and from 38 degrees North to 13 degrees South of the equator. All species are climbers and grow in semi-deciduous forests, scrub or grassland vegetations of the semi-arid or moist tropical habitats. One species, D. villosa, occurs in East Asia including Japan. Most species occur between 0 and 1200 m a.s.l., some reach 2000 m, rarely species are restricted to high elevations. Dunbaria species may be useful for breeding programmes of pigeonpea, Cajanus cajan (L.) Millsp., as the genera are related.
