Asplenium septentrionale (L.) Hoffm.is a small herbaceous isospore plant. The study presents the
morphological description of the spores of Asplenium septentrionale (L.) Hoffm in Albania. At the same time,
a comparison of the palynological data of this species with those from the literature is made. The spores are
monolete and of the bilateral type. So, they have only one laesura. The spores have oval to ellipsoid, to bean
shaped contours. The surface of the exine is smooth (psilate) and of uniform thickness. The exine is about 1.5
um thick.
The perispora has spiny cristae, not uniform, but well developed. The perispore folds merge at the base. They
form wrinkles of different 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 um. Through this study, more information is provided
on the morphological features of the spores of this species of our country compared to the literature data.
The material for the study was taken fresh in the Kolosian, Kukës area, Albania. The study was carried out
with a Motic BA310 light microscope with 400x and 1000x magnification.
