Heterochronical trends promote labile floral strategies in Eugenia
Comparative ontogeny elucidates subtle changes in developmental rate, known as heterochrony, that discretely alter morphology between species. Vasconcelos et al. show how these trends explain evolution of Eugenia...
The nature of ‘bracteoles’ in Atripliceae
The tribe Atripliceae (Chenopodiaceae) has been characterized by having perianthless female flowers surrounded by two accrescent bracts/bracteoles. Flores-Olvera et al conduct a floral ontogenetic study using LM and SEM...
