Rediscovery of Banisteriopsis magdalenensis(Malpighiaceae): Notes on morphology, distribution, and ecology of an endemic and threatened species from the Atlantic Forest of Brazil

We present the rediscovery of Banisteriopsis magdalenensis, including an updated morphological description, illustrations, distribution map, and notes on conservation, ecology and taxonomic affinities. The species is endangered and appears to be confined to rocky outcrops in the Atlantic Forest of Northern state of Rio de Janeiro, Brazil, where two populations were found growing apart within the limits of Desengano State Park.
