New species of Eschweilera (Lecythidaceae) from southern Brazil
Abstract:
Eschweilera tetrapetala Mori and E. alvimii Mori are described and compared with E. compressa (Vellozo) Miers, the only other species of this genus known to have four petals. It is concluded that this small group of species probably evolved from a common ancestor whose range was fragmented by climatic and vegetational changes in the Pleistocene. The distributions of E. compressa and E. alvimii support the hypothesis that moist forest refuges existed around Rio de Janeiro and southern Bahia/northern Espírito Santo throughout the Pleistocene. © 1981 New York Botanical Garden.
