Original diagnosis/description

Stamen laminar. Anthers tetrasporangiate, dithecate. Thecae positioned close to the stamen margin and separated by a massive, broad connective. Stamen apex rounded without an apical extension. Dehiscence longitudinal. Staminal tissue with larger cells, probably ethereal oil cells. Pollen monocolpate, circular in equatorial view, semitectate-reticulate. Reticulum loosely attached, heterobrochate. Aperture long, reaching the equator, with distinct margins. Columellae short.

Etymology

From Greek elasma for lamina and stemon for stamen.
