“…It has been suggested that the outer integuments are cup shaped and asymmetrical (Bouman, 1984). However, recent developmental and morphological studies have shown that in many basal angiosperms the outer integument is sharply asymmetric and hood shaped, that is, it is lacking on the concave (funicular) side of the ovule (Matsui, Imaichi, and Kato, 1993;Umeda, Imaichi, and Kato, 1994;Imaichi, Kato, and Okada, 1995;Igersheim, 1997, 1999;Endress, 1997, 1998; see also Johri, Ambegaokar, and Srivastava, 1992).The origin of bitegmy has been variously interpreted in contrast to the agreement on the origin of the first (inner) integument by fusion of telomes (Herr, 1995). Crane (1985Crane ( , 1986 and Doyle and Donoghue (1986, 1987) postulated that the outer integument is derived from the leafy lamina of a Caytonialike ancestor, while the carpel enclosing ovules is derived by lateral expansion of its leaf axis.…”

“…Positions sister to Laurales as a whole and nested within Calycanthaceae were one step less parsimonious. Here we follow the result of Doyle et al (2008) because it is based on a data set that included far more characters than Crepet et al (2005), many derived from indepth analyses of gynoecial morphology (e.g., Igersheim and Endress, 1997). Both most parsimonious positions imply that Virginianthus provides a minimum age for the crown node of Laurales (Figure 1).…”

“…Sin embargo, los análisis moleculares recientes y la revisión de evolución de caracteres en contextos filogenéticos aportan evidencia de que la condición ascidiada es plesiomórfica (Doyle & Endress, 2000;Soltis, Soltis, Endress, & Chase, 2005;Endress & Doyle, 2009). La teoría del origen plicado de los carpelos se basó en el estudio de este carácter en Winteraceae, que además es la única familia en Eumagnoliales que presenta las dos formas de carpelos, ascidiado y plicado (igersheim & Endress, 1997;Soltis et al, 2005).…”

“…No obstante, igersheim & Endress (1997), y Endress & Doyle (2009) demostraron que los carpelos de Winteraceae (y de su grupo hermano, las Canellaceae) se encuentran completamente cerrados de manera posgénita por fusión temprana de las epidermis inmaduras. Sin embargo, otras características permiten diferenciar estas dos familias hermanas: (1) el ovario paracárpico en Canellaceae y apocárpi-co o eusincárpico en Winteraceae (una condición paracárpica atípica ocurre en Takhtajania perrieri; ; (2) el cierre del carpelo por secreción en Canellaceae pero no en Winteraceae (igersheim & Endress, 1997); (3) presencia de estilo y de estigma lobado en Canellaceae y sésil en Winteraceae con una cresta corta o una doble cresta larga (igersheim & Endress, 1997); (4) en Canellaceae estigma papilado unicelular y fuertemente secretor; y unicelular-papilado o multicelular-multiseriado-papilado y débil o fuertemente secretor en Winteraceae (igersheim & Endress, 1997).…”
