). Pollen grains are about 15 µm in diameter. The grains are folded and while the apertures of all the grains are poorly exposed the pollen appears monoaperturate, probably monocolpate. The pollen wall is semitectate-reticulate with a homobrochate reticulum (Textfig. 27d). There is no trace of orbicules on the inside of the anther wall.
