distinctive shape of a not germinated pollen in polar view.
ref. sculture. Very minute tectum perforations which are smaller than the distance between two perforations.
ref. pollen. Colpi in open order on the surface of the sporoderm.
ref. pollen. Colpi which contain pori in open order on the sporoderm surface.

reticulate sculpture in semitectate pollens.
fold in the sporoderm surface.
(POLLEN) - pollen grains with a visible polarity.
imaginary line connecting the two poles.
view from which it is possible to observe the shape, sculpture, cytoplasm and apertures of a pollen grain in polar position.

it consists of many pollen grain massulae.
pollen unity composed of 8-10-12-16-24-32 pollen grains.
ref. sculture. Reticulate sporoderm with muri composed of several rows of bacula.
sporoderm with a series of plycae (greater than 6).
pollen grain with aperture made up by pore.
aperture like an central enlargement of the colpus similar to a pore.
simple aperture more or less of circular form.
ref. pollen. When the pollen ratio P/E is of 1.33 to 2.00.
Prolate - spheroidal
ref. pollen. When the pollen ratio P/E is of 1.00 to 1.14.
focus point in the proximal polar region of the pollen referring to the position taken in the anther techa.
false aperture. Sporoderm furrow similar to a non functional colpus.
sporoderm with regular but not clearly seen spinae.
false aperture. Sporoderm introflection like an unfunctional porus.
ref. sculture. Sporoderm with more or less smooth surface.
ref. sculture. Sporoderm with smooth clavae.
ref. sculture. Sporoderm with pimpled surface.
ref. sculture. Sporoderm with pimpled and baculate surface.
