Contribuição ao estudo da nervação foliar de plantas da Flora Amazônica. ll-Fagara Prancei Albuq. (Rutaceae)

Abstract

The present paper is the continuation of a catalogue of foliar venation of plants of the Amazonian flora, dealing with a source of data for ecology and paleobotany, and a set of auxiliary characters in taxonomy. Results indicate that certain differences in the arrangement of vein network, in the number of translucid glands per mm2, and in the gland position along leaflet margin allow the studied species to exclude from other four species belonging to the camptodroma group. A key for comparing specific discrimination among the species of genus Fagara belonging to the camptodroma group of Ettingshausen's vein patterns is presented.
