- Diagnosis
- Flower bisexual, with ca. 20 strap-shaped tepals preserved (original number probably 30–40). Perianth phyllotaxis not conclusively established but probably whorled. Stamen and carpel phyllotaxis whorled but somewhat irregular. Stamens ca. 50, broad, scale-like, and spatulate, ending in short connective apex. Anther ca. 2/3 to 3/4 length of stamen. Filament and anther not differentiated, entire stamen smoothly tapering to base. Thecae on ventral (adaxial) surface, four pollen sacs probably embedded. Pollen not preserved. Staminodes absent. Carpels ca. 100, small, short, with ovary locule taking up most of length. Ovules not preserved, but locule shape suggests that carpels are uniovulate. Distal part of carpel pointed and curved toward center of gynoecium, lacking distinct style. Receptacle hemispherical to almost 3/4 spherical in gynoecial region.
