Abstract

CABOCO, Rafael Brune; ROLIM, Thiago Prates; SARTORI, Ângela Lúcia Bagnatori  and  SCIAMARELLI, Alan. Leguminosae-papilionoideae from the parque estadual das Várzeas do Rio Ivinhema, Mato Grosso do Sul State, Brazil. Biota Neotrop. [online]. 2012, vol.12, n.2, pp. 57-70. ISSN 1676-0603.  http://dx.doi.org/10.1590/S1676-06032012000200007.

This study aims to evaluate the richness of the Papilionoideae species found in the Parque Estadual das Várzeas do Rio Ivinhema (PEVRI), which is located in the southeast region of Mato Grosso do Sul, Brazil, and investigate if the habits of this Leguminosae group vary in different formations of the park. Monthly collections, including all habits, were made by walking along pre-established trails, from September 2004 to September 2009. The PEVRI includes Seasonal Semideciduous Forest, Seasonal Alluvial Semideciduous Forest and fields. Twenty-three species distributed in 16 genera and 5 tribes were recorded. Phaseoleae was noted with 7 genera, followed by Dalbergieae with 6 genera and Desmodieae, Indigofereae and Crotalarieae with only 1 genus in each species. Among the 16 recorded genera, Crotalaria L. (4), Aeschynomene L. (3), Desmodium Desv., and Vigna Savi (2) were the most representative. The Papilionoideae with herbaceous and subshrub habits were predominant in humid and pastures, while arboreous species and lianas were recorded in the Seasonal Semideciduous Forest. Nine species of Papilionoideae were recorded in humid grasslands, eight species in Seasonal Semideciduous Forest, and only one in Alluvial Semideciduous Forest. Papilionoideae found in the PEVRI have also been recorded in cerrado, Seasonal Semideciduous Forest and Pantanal, except Andira inermis, which does not present a reference for Seasonal Alluvial Semideciduous Forest.
