Original protologue

Flower pedicellate, structurally bisexual, whorled. Floral receptacle shallow. Perianth of nine tepals in three whorls of three. Three outer tepals thick, sepal-like, imbricate, and covering the inner perianth parts. Six tepals of the two inner whorls free, petallike, with a thin blade; outer petaloid tepals with a narrow base; inner petaloid tepals with a broad base. Androecium probably of 18 stamens in several whorls. Stamens with long, broad, and fleshy bases and short triangular anthers. Anthers dithecate and tetrasporangiate, with a broad connective that tapers into an apical extension; dehiscence extrorse. Anther wall with an inner lining of small spherical orbicules. Pollen circular in polar view, monoaperturate, trichotomocolpate, and monocolpate, with a distinct aperture margin and granular aperture membrane. Tectum perforate, coarsely rugulate; infratectal layer probably columellate. Gynoecium superior, apocarpous, of six carpels (rarely five), each with a restricted stigma.

Etymology
