Özet
Verbascum (Scrophulariaceae, Lamiales), usually known as “Mullein”, is widely
distributed in Eurasia and North Africa, but the highest taxa diversity is in Anatolia,
the southern Balkans, the Middle East, the Caucasus and northwestern Iran and is
represented by approximately 360 species in the World. As hybridization is very
dense in the genus Vesbascum, the high frequency of morphological variations has
been intricated in species delimitation. In this study, pollen and capsule morphology
of three hybrid Verbascum taxa [Verbascum × calcicola Hub.-Mor., V. ×
kotschyoides Hub.-Mor., and V. × nusaybinense Hub.- Mor.] were investigated. They
are hybrids wild distributed in the province of Mardin in Southeastern Anatolia.
Pollen slides were prepared according to the Wodehouse method, pollen and capsule
morphologies were examined with microscope. In general terms, aperture types were
tricolporate, but also tricolpate aperture types were observed. The shapes of the
pollen grains were determined as oblate-spheroidal and subprolate. The sculpture
was reticulate in all cases. The seeds not developed. The capsules are pubescent,
densely covered by branched hairs, or loosely by glandular hairs, depending on taxa.
The results of this study showed that morphological features, such as pollen shape,
polar axis (P), equatorial diameter (E), aperture type, exine and intine thickness,
colpus, and por measurement, show differences that can be taken into consideration
in the systematic discrimination within the taxa. The capsule showed that substantial
taxonomic insight can be gained from examining the capsule characteristics of
Verbascum, particularly at the species level.
