Wing of perianth segments horizontal or slightly reflexed, semiorbicular, dry membranous, margin entire or incised.

The spores are monolete, bilaterally symmetric, elliptic in polar view, and semiorbicular or reniform in equatorial view.

Seeds maroon-brown, semiorbicular, flat.

Disk lobes semiorbicular, apex entire; leaves spreading, semiterete or subclavate.

bracteoles semiorbicular, connate, ca. 1 mm.

Hypanthium cup-shaped, campanulate, subfunnel-shaped, or semiorbicular, apex repand or shallowly 4-lobed.

persistent sepals slightly thickened, approximately leathery, semiorbicular or nephroid, 3. 5-4 mm wide.
