Abstract

In forest remnants of the Northwest region of Paraná (Brazil) several lianas that can affect the development of arboreal and shrubby species are found. Among the lianas Arrabidaea mutabilis Bur. & K. Schum. stands out for its fast growth and high number of alate seeds. The morphologic and anatomical analysis of the seedling and tirodendro Arrabidaea mutabilis development is the object of the present study. The botanical material was sectioned by freehand and rotation microtome, using conventione anatomical techniques. Seedling is phanerocotylar and epigeal, with foliaceous cotyledons and simple and opposite eophylls; the epicotyl has stem structure. There are several simple and compound eophylls in the tirodendro, the first compound metaphyll is formed only in the fourteenth node. The primary root is triarch/pentarch and the hypocotyl presents root-shoot transition structure. Cotyledons, eophylls and metaphyll are dorsiventral leaves. Seedling is of the Macaranga type.
