Stamens tetrasporangiate and dithecate with sessile, basifixed anthers attached directly to the common stalk. Thecae straight and parallel in each stamen, but the thecae of the two stamens diverging apically. Apex of the two stamens with prominent coriaceous projection that is also seen on the median axis-like structure. A bundle extends from the common base into the apical projection of the two stamens and the median axis-like structure. Pollen grains monocolpate, semitectate-reticulate.
