Asplenium scolopendrium L (Aspleniaceae Newm) is a homosporous herbaceous plant. This
study presents a detailed morphological analysis of spores from Asplenium scolopendrium L. in Albania.
At the same time, a comparison of palynological data of this species with those obtained from the
literature was made.
The spores are of the bilateral type. They are monolete. So they only have one laesura. The spores have
oval to ellipsoidal contours, up to bean-shaped. The surface of the exine is smooth (psilate) and of
uniform thickness. The exine is about 1.5 µm thick.
The perispore is cristate - fenestrate, and is well developed. The folds of the perispore join at the base.
They form wrinkles of various shapes, giving the impression that they are independent of each other. The
size of the perispore ornaments varies. They can reach up to 4-5 µm.
Through this study, more information is provided on the morphological features of the spores of this
species of our country compared with the literature data.
The material for the study was taken fresh in the Pogradec area, in SouthEast of Albania. The study was
done with a Motic BA310 light microscope with 400x and 1000x magnification.
