Diagnosis

Flower probably staminate, perianth glabrous, tepals in two whorls of 5 each, those of the outer whorl small, quincuncial, unequal, narrowly to broadly elliptic, oblanceolate, or obovate, obtuse, with 3–7 main veins interconnected by a network of veinlets, tepals of the inner whorl larger and up to 3 times longer than the outer tepals, explanate, ± equal, connate basally, broadly ovate, acute or acuminate, with ca. 7–9 main veins that branch above and are similarly interconnected, stamens 5, inserted opposite the inner tepals on their connate basal portion, filaments linear, longer than anthers, glabrous, anther attachment basal, anthers angular-oblong, bilocular, dehiscence latrorse by oblique slits, epidermis papillate, connective not prolonged, anthers absent from 3 filaments, perhaps due to insect predation (note insect trapped under the air bubble), gynoecium probably 0, pedicel 0 or detached below outer tepals, pollen unknown.
