Comparative floral structure and systematics in Cucurbitales (Corynocarpaceae, Coriariaceae, Tetramelaceae, Datiscaceae, Begoniaceae, Cucurbitaceae, Anisophylleaceae)

Abstract: Floral structure, including morphology, anatomy and histology, was comparatively studied in representatives of all seven families of Cucurbitales as currently circumscribed by other authors based on molecular analyses and including Corynocarpaceae, Coriariaceae, Tetramelaceae, Datiscaceae, Begoniaceae, Cucurbitaceae and Anisophylleaceae. Three superfamilial clades are supported by floral structure: Tetramelaceae/Datiscaceae, Tetramelaceae/Datiscaceae/Begoniaceae and Corynocarpaceae/Coriariaceae. Anisophylleace… Show more

“…Schönenberger & Conti (2003) demonstrated that petals in the small families Penaeaceae, Oliniaceae, Rhynchocalycaceae and Alzateaceae (Myrtales) can be either present and small, or absent with a transfer of petaloidy to the hypanthium and sepals. A similar evolution characterizes Begoniaceae (Cucurbitales), where petals are lost except in the monotypic Hillebrandia (Matthews & Endress 2004). Apart from the well-studied Arabidopsis thaliana, relatively few evodevo studies have been carried out in rosids (except some Carica and Polygalaceae).…”

“…Matthews y Endress (2004) observaron que las células del tegumento externo del óvulo de B. incana tienen inclusiones de taninos en la zona calazal, en B. gracilis se encontraron células muy grandes con engrosamientos lignifi cados, pero no taninos.…”

“…Algunas de las características encontradas en Begonia gracilis, como el desarrollo del saco embrionario tipo Polygonum, el micrópilo anfístomo, la presencia de tapete tegumentario y de una capa de aleurona, la fusión de los núcleos polares previa a la fecundación, la meiosis simultá-nea y el polen bicelular, han sido mencionadas independientemente para ciertas especies de Begonia, pero no han sido exploradas en un mismo estudio (Swamy y Parameswaran, 1960;Davis, 1966;Maheswari-Devi et al, 1982;Johri et al, 1992;Matthews y Endress, 2004). Al parecer estos caracteres son constantes para el género Begonia.…”
