A species well travelled – the Dodonaea viscosa (Sapindaceae) complex based on phylogenetic analyses of nuclear ribosomal ITS and ETSf sequences
Abstract Aim To determine the evolutionary history of the widely studied, cosmopolitan polymorphic species Dodonaea viscosa (hop bush, varnish tree). Location All continents except Antarctica, extending from 44° S (in the South Island of New Zealand) to 33° N (in California and Arizona). Methods For...
