Original diagnosis/description

Staminate inflorescences sessile, composed of about 50 closely spaced flowers. Flowers surrounded by membranous tepals, about the same length as the stamens. Apical extension of connective clearly delimited at the base, peltate; less than one fifth the length of the pollen sacs, not projecting beyond the tepals. Papillae arise from the contiguous surfaces of adjacent anthers just below the apical connective. Pollen grains small, prolate and coarsely reticulate.
