- Stamens with long tetrasporangiate and
dithecate anthers. Pollen grains small, almost circular in
equatorial outline, monocolpate, colpus extending for the
full length of the grains. Exine semitectate-reticulate and
columellate. Reticulum heterobrochate; heteropolar with
coarser reticulum on proximal face than on distal face. Muri
smooth with flattened to slightly rounded profiles, supported
by long distinct columellae. Colpus margin distinct,
microreticulate, lacking psilate regions around the end of the
colpus. Colpus membrane granular. Orbicules large, dentate,
densely scattered on inner surface of the anther wall.
