Original diagnosis/description

Follicles stipitate, various in shape but commonly elongate elliptical to semicircular in lateral view, laterally flattened, with rounded apex and slightly pointed base. Ventral slit of follicle extending for the entire length of follicle and over the topological apex to the abaxial side, where the stigma is located. Stigma indistinct, double crested with smooth surface at the distal end of the ventral slit. Follicle surface smooth or slightly wrinkled. Follicle wall served by one dorsal and two lateral bundles. Placentation marginal-linear, on each side of the ventral slit, with up to eight ovules, of which most or all developed into mature seeds. Ovules anatropous and apparently bitegmic, generally not filling the ovary cavity. Seeds smooth, elongate ellipsoid with rounded chalaza and slightly pointed micropyle, as well as distinct funicle and raphal ridge.

Etymology
