A flórula fanerogâmica das restingas do estado do Pará. Família Sapotaceae Jussieu

Abstract

The coastal region of Brazil presents a great diversity of plant communities. From the floristic point of view, the restingas of southeastern and southern Brazil are the best studied, unlike the coast of the state of Pará, which 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 activities. The objective of the present work was to carry out taxonomic studies of the species of the Sapotaceae Juss. family, which occur in the restingas of the Paraense coast, northeast of the State. 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 herbaria. Several families of plants are distributed in this area, among them, the Sapotaceae Juss., which is represented in Brazil by 12 genera and 103 species. In the restingas of Pará, the genera Pouteria Aublet, Micropholis (Grisebach) Pierre and Manilkara (F.Alle.) Monachino occur. These are represented by the following species: Pouteria ramiflora (Mart.) Radlk. Tree about 4 m tall; leaves ca. 38-48 mm wide and 70-95 mm long, alternate arranged in spiral, coriaceous, oblong-lanceolate, apex acuminate, base obtuse, margin entire; inflorescence axillary, fascicle-shaped. Micropholis oenulosa (Mart, & Eichl.) Pierre. Shrub ca. 3 m tall; leaves ca. 30-82 mm long and 20-38 mm wide, alternate, oblong-lanceolate, apex acuminate, base obtuse, margin repanda; axillary inflorescence, in fascicle; flower buds ferruginous. Manilkara triflora (F. Alie.) Monachino. Tree 4m high; leaves ca. 21-63 mm long and 12-26 mm wide, alternate, spiral, obovate-oblong, apex retuse, base cuneate, margin revolute; flowers in fascicles; fruit immature. Manilkara bidentata subsp. surinamensis (Miq.) T.D.Penn. Tree ca. 3 m tall; leaves ca. 70-210 mm long, alternate, oblong, rounded apex, cuneate base, entire margin.
