Another mangrove tree from the Amazon coast: Avicennia schaueriana Stapf & Leechm. ex Moldenke, the second species of the genus in Brazil. Flowers of A. schaueriana have short stamens + glabrous inner corolla lobes (A. germinans, from last week's toot: long stamens/tiny hairs on the inner corolla lobes). In our area, the leaves of A. schaueriana are always obovate and rounded at the tip. The species is less common here, mainly found near beaches. #Acanthaceae #trees #mangroves #Amazonas #botany
