75 mm, anatropous, with a tuberculed, hexagonal-celled exotesta.
This analogy is not so fanciful as it seems, if the suggestion of Endress (2011) that anatropous ovules are ancestral in angiosperms.
The ovary contains a single, basal, anatropous ovule (Goetghebeur, 1998).
Ovule: (0) orthotropous, bitegmic; (1) anatropous or hemianatropous, bitegmic; (2) anatropous, unitegmic (Davis, 1966; Palkovic, 1974; Orchard, 1975; Corner, 1976; Cronquist, 1981; Dahlgren & Thorne, 1984; Webb & Gornall, 1989; Kubitzki, 1993b).
