The species composition of an area of 0.5 hectare of seasonal inundation forest located between the
blackwater Negro River and the whitewater Solimões River at Lago Janauari near Manaus, Brazil, was
studied. Sixty-six arboreal species representing 55 genera and 31 families were recorded. Total basal area
was 15 m² and bole volume was 125 m³. The most abundant species were Pouteria sp. (Sapotaceae) and
Pterocarpus amazonum (Fabaceae). The highest basal area per species was 2.15 m² for Calophyllum
brasiliense (Clusiaceae). The vegetation in the study area represented an ecotone with characteristic tree
species of the seasonal inundated forests in the whitewater (várzea) or/and blackwater (igapó) region of
central Amazonia. Following the terminology of Amazonian forest types subject to inundation (PRANCE 1979) it is therefore named "seasonal várzea & igapó" or "mixedwater" inundation forest.
