ResumoA survey was carried out in a patch of riparian forest lying along the Rio Grande in Madre de Deus de Minas (21°29'22''S, 44°22'35''W, c. 900-950 m altitude), state of Minas Gerais, south-eastern Brazil. The forest patch is characterised as Montane Semideciduous Seasonal Forest, on the upland slopes, an d Alluvial Semideciduous Seasonal Forest, on the seasonally flooded alluvial bed. The soils are Haplustox, on the slopes, and Ustifluvent, on the alluvial bed. The area was sampled with 71 (15 × 15 m) contiguous plots, totalling a sample area of 1,597 ha. A total of 1,738 trees with circumference at the base of the stem (cbt) ≥ 15.7 cm were recorded in the sample. The trees were distributed in 116 species, 90 genera and 47 families. Most trees (78,3%) belonged to ten families, the most important of which were: Myrtaceae (16,6%), Euphorbiaceae (10,0%), and Annonaceae (9,4%). The four families with the higher number of species were Myrtaceae (11), Fabaceae (9), Lauraceae (8), and Rubiaceae (8). The most abundant species on the upland slopes were: Xylopia brasiliensis (150), Myrcia multiflora (119), and Geonoma schottiana (105). On the alluvial bed Salix humboldtiana (104) and Inga vera (89) encompassed 95,1% of all trees.
