EVOLUTION OF FLORAL MORPHOLOGY AND POLLINATION SYSTEM IN BIGNONIEAE (BIGNONIACEAE)
(BOTANICAL SOC AMER INC, 2010)
The radiation of angiosperms is associated with shifts among pollination modes that are thought to have driven the diversification of floral forms. However, the exact sequence of evolutionary events that led to such great ...
Floral development and vasculature in Eriocaulon (Eriocaulaceae) provide insights into the evolution of Poales
(2021-10-08)
Background and Aims: Floral developmental studies are crucial for understanding the evolution of floral structures and sexual systems in angiosperms. Within the monocot order Poales, both subfamilies of Eriocaulaceae have ...
ELUCIDATING ENIGMATIC FLORAL ISSUES IN COPAIFERA LANGSDORFFII DESF. (LEGUMINOSAE, CAESALPINIOIDEAE)
(UNIV CHICAGO PRESS, 2010)
This study focuses on the floral development of Copaifera langsdorffii to elucidate uncertain features in its floral morphology, such as the tetramerous calyx, lack of petals, blackened anthers and their supposed sterility, ...
Comparative floral morphology and anatomy of Thurniaceae, an early-diverging family in the cyperids (Poales, Monocotyledons)
(Springer, 2020-04-29)
Thurniaceae are positioned at the base of the cyperids, in Poales, as a sister group of Cyperaceae + Juncaceae. However, Rapateaceae + Mayacaceae have emerged related to these families in a recent phylogenetic study. ...
A comparison of floral integration between selfing and outcrossing species: A meta-analysis
(Oxford University Press, 2016-02)
Background and Aims Floral integration is thought to be an adaptation to promote cross-fertilization, and it is often assumed that it increases morphological matching between flowers and pollinators, increasing the efficiency ...
Partilha de polinizadores por espécies quiropterófilas em um fragmento de Cerrado, São Paulo
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2010-06-29)
Flowering plants need some external pollen vectors to accomplish sexual reproduction. For plants, the access of sexual mates by pollinators agents is a limiting factor, wich make pollen vectors a critical resource for ...
Floral nectaries in Sapindaceae s.s.: morphological and structural diversity, and their systematic implications
(Springer Wien, 2017-04)
We investigated the morphology and structure of the floral nectary in 11 Neotropical genera belonging to the subfamilies Dodonaeoideae and Paullinioideae (Sapindaceae) from southern South America representing three tribes ...
