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 ...
Morpho-Anatomy and Ontogeny of the Floral Nectaries of Cardiospermum grandiflorum and Urvillea chacoensis (Sapindaceae)
(Finnish Zoological Botanical Publishing Board, 2009-12)
The morphology, anatomy and ontogeny the floral nectaries of two species of Sapindaceae (Paullinieae), viz. Cardiospermum grandiflorum and Urvillea chacoensis, were studied using light and scanning electron microscopy. ...
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, ...
Floral development and vascularization help to explain merism evolution in Paepalanthus (Eriocaulaceae, Poales)
(2016-01-01)
Background. Flowers in Eriocaulaceae, a monocot family that is highly diversified in Brazil, are generally trimerous, but dimerous flowers occur in Paepalanthus and a few other genera. The floral merism in an evolutionary ...
Floral organogenesis and vasculature in Mayacaceae, an enigmatic family of Poales
(2019-08-01)
Mayacaceae are a small and monogeneric aquatic family including 4–6 species and with an unstable phylogenetic position within Poales. Therefore, the floral development and vasculature were studied in Mayaca fluviatilis and ...
Gynoecial ontogeny of Anthurium: contributions for floral developmental studies in Araceae (Alismatales)
(Canadian Science Publishing, Nrc Research Press, 2015-01-01)
Studies on floral development have widened the knowledge on the floral morphology of Araceae, particularly in genera delimited through classical taxonomic treatments. In Pothoideae, floral ontogenetic studies are limited ...
Evolutionary lability in floral ontogeny affects pollination biology in Trimezieae
(Wiley-Blackwell, 2021-05-21)
Premise There is little direct evidence linking floral development and pollination biology in plants. We characterize both aspects in plain and ornamented flowers of Trimezieae (Iridaceae) to investigate how changes in ...
Anatomy, pollen, and chromosomes of adenoa (turneraceae), a monotypic genus endemic to Cuba
(Springer, 2012)
The monotypic genus Adenoa is endemic to Cuba. Its name alludes to the presence of minute glands on the petal margin, identified in the present study as lachrymiform colleters. Here we describe the morphological, anatomical, ...
Floral development of the Ornithocephalus clade (Oncidiinae, Orchidaceae): The origin of the tabula infrastigmatica, gynostemium appendices and labellar callus
(2021-04-01)
The Ornithocephalus clade comprises small epiphytes distributed in 12 genera and c. 120 species. Their flowers have complex structures, the homologies of which are difficult to interpret. Through ontogenetic studies, we ...
