Summary: | Palynomorphological characteristics of Campanula lingulata, the
Balkan-Carpathian endemic species growing in Serbia, have been investigated
using light microscopy and scanning electron microscopy for the first time,
in order to provide some information helpful for a better understanding of
the taxonomic position of this species within the genus, as well as to
contribute to the pollen atlas of Serbian apiflora. The pollen grains are
radially symmetrical, isopolar, 3-zonoporate and medium-sized monads
oblate-sphaeroidal in shape. Mean of the polar axis (P) is 27.6±1.9 μm, while
the average length of the equatorial axis (E) is 28.8±1.6 μm. The apertures
are operculate. The sculpturing pattern of the exine is
microreticulate-microechinatae. The exine surface is covered with evenly
distributed supratectal spinules of variable length and sparse granules. The
longest supratectal spinules are 0.64±0.05 μm in length and the smallest
sculptural elements are less than 0.2 μm high. The microechinae density per
sample area of 5 μm x 5 μm averages 17.4±2.4. [Projekat Ministarstva nauke
