Costa, sp. nov. is a herb restricted to the region of the Recôncavo; Begoniaelianeae Gregório & J.A.S. Costa, sp. nov. is a shrub endemic to the Atlantic forest of the ...
متن کاملGenetic diversity and gene flow in the morphologically variable, rare endemics Begonia dregei and Begonia homonyma (Begoniaceae).
Begonia dregei and B. homonyma (Begoniaceae), rare plants endemic to coastal forests of eastern South Africa, are two closely related species with high levels of variation among populations in the shape of leaves. Distribution of genetic variation and genetic relatedness were investigated in 12 populations of B. dregei and seven of B. homonyma using polyacrylamide gel electrophoresis. Twelve of...
