A flórula fanerogâmica das restingas do Estado do Pará. Família Leguminosa Mimosoideae (Mimosaceae)

Abstract

The coast of the state of Pará has an extensive area covered by restingas of great beauty and economic value, but little known from the botanical point of view, and is threatened by human action. The phanerogamous flora of the restingas of Pará is composed of 6 plant formations and about 300 species. The objective of the present work was to carry out taxonomic studies of the species of the Leguminosa Mimosoideae family, occurring in the restingas of the Paraense Coast. For this study a survey of them was done along the coast of Pará, the specimens were collected, identified by comparison with other specimens in the MG and IAN herbaria and through existing literature, and deposited in the MG herbarium. In this area, several families of plants are distributed, among them, the Leguminosa Mimosoideae, which is represented in Brazil by 60 genera and 3000 species. In the sandbanks of Pará, the genera Acacia, Entada, Inga, Mimosa, Pitbecellobium and Stryphnodendron occur. These are represented by the following species: Acacia farnesiana (L.) Willd., Entada polystachya (L.) DC., Inga alba (Sw.) Willd., Inga ruiziana G. Don., Inga beteropbylla Willd., Inga pilo sula (Rich.) J. F. Macbr., Inga tbibaudiana DC., Mimosa balansae Micheli, Pithecellobium cochleatum (Willd.) Mart. and Stryphnodendron pulcherrimum (Willd.) Hochr.
