TAXON, Volume 75, Issue 2, April 2026.Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

bioRxiv, 2018 About 15,000 angiosperm species (∼6%) have separate sexes, a phenomenon known as dioecy. Early work reported a lower species richness in dioecious compared to non-dioecious sister clades, which was taken to suggest that dioecy might be an evolutionary ...

Two in the bush: On the evolution, distribution and natural history of dioecy in Australian Solanum
, 2006 The causes, consequences, and correlates of dioecy have been the subject of much discussion since the days of Charles Darwin\u27s work. Several more recent authors have stressed the importance of informing this body of theory with studies that focus on ...
