The current infrageneric classification accepts 12 sections - with T. sect. Tradescantia being further divided into four series - and assimilates many concepts adopted by previous authors. Recent molecular-based phylogenetic studies indicate that the ...
متن کاملCytogeography of Callisia section Cuthbertia (Commelinaceae)
