Annotations: The 2 apertures are situated in the equator and parallel to it, therefore the aperture condition is disulcate and not dicolpate (in this case the apertures are orientated meridionally); the shape of hydrated pollen is spheroidal to oblate with elliptic outline, isopolar to indistinctly heteropolar.
