HOC, Patricia S.; PALACIOS, Ramón A.  e  MOM, María P.. Novelties on species of Vigna and Inga (Leguminosae) from Argentina. Bol. Soc. Argent. Bot. [online]. 2006, vol.41, n.3-4, pp.327-332. ISSN 1851-2372.

During the study of the subtribe Phaseolinae (Leguminosae, Phaseoleae) and the tribe Ingeae (Leguminosae, Mimosoideae) for the Flora of Jujuy we detected the existence of collections which confirm that: 1) Vigna candida (Vell.) Maréchal, Mascherpa & Stainier, till now, known growing in the Paraná basin with the southern limit of distribution in the province of Misiones, now is reported as a component of the first slopes of Yungas rain forest at the province of Jujuy. 2) Vigna luteola (Jacq.) Benth., a species of african origin and dispersed over the pantropical areas, was known in our country, growing in the marginal forests of the Paraná and Uruguay basins southern to Buenos Aires. The studied collections allow us to amplify the distribution of the species to the provinces of Jujuy, Salta, Santiago del Estero and Córdoba, perhaps introduced by humans. 3) Inga saltensis Burkart was described growing in the south of Bolivia and in the province of Salta (Argentina) with its southern limit of distribution in the Capricorn tropic. A recent collection allow us to extend the distribution of the species southern to the north of the province of Jujuy, also, the fruit dimension is modified.
