- Diagnosis
- Isobilateral, dorsi ventral, pedicellate ovulate
fructification consisting of a receptacle with a broad,
peripheral wing. Receptacle lanceolate, elliptical to
lorate, with a high length to width ratio (2:1 to 7:1);
apex extended to form a pronounced, acuminate
extension or spine. Wing broad, slightly less than or
equal to width of receptacle, with fine striae and fluting
orientated perpendicular to receptacle, flute definition
decreasing towards the margin. Wing margin entire,
discontinuous at base, forming a truncate to convex
lobe on either side of pedicel insertion. Wing tapering
abruptly at apex near base of apical spine. Fertile
surface of the receptacle bearing numerous, closely
spaced seed scars. The sterile surface is characterized
by a fan-shaped network of bifurcating and
anastomosing veins, with strongly parallel venation
along the central axis of the receptacle. Marginal veins
on receptacle pass between the seed scars and are
continuous with flutes developed on the wing.
