Acacieae Benth. (Leguminosae, Mimosoideae) in Minas Gerais, Brazil

Acacieae Benth. (Leguminosae–Mimosoideae) comprises more than 1450 species and is composed of five genera in the current circumscription: Senegalia Raf., Mariosousa Seigler & Ebinger, Vachellia Wight & Arn., Acacia Mill., and Acaciella Britton & Rose. This work describes the diversity of the Tribe Acacieae in the state of Minas Gerais. The studies were based on the analysis of specimens from herbaria, field observations, and the collection of botanical materials. The study provides descriptions, illustrations, an identification key, common names, and data on the geographic distribution and flowering and fruiting of these species. Eighteen species belonging to this tribe were recognized in the state. For the first time, we report the occurrence of Senegalia velutina DC. in Minas Gerais. The species are distributed in the three biomes in the state: Atlantic Forest, Cerrado, and Caatinga. Senegalia bahiensis (Benth.) Seigler & Ebinger, S. giganticarpa (G. P. Lewis) Seigler & Ebinger, S. lacerans (Benth.) Seigler & Ebinger, S. lewisii (Bocage & Miotto) L. P. Queiroz, S. limae (Bocage & Miotto) L. P. Queiroz, S. martii (Benth.) Seigler & Ebinger, S. paganucci (Willd.) Seigler & Ebinger, S. pteridifolia (Benth.) Seigler & Ebinger, S. serra (Benth.) Seigler & Ebinger, and S. velutina have been designated for inclusion on the list of endangered species in Minas Gerais.
