“…The genus Verbascum with 360 species (Judd et al, 1999) worldwide and 257 species and 132 supplement hybrids in Turkey, and has been divided into 13 artificial groups in Turkey (Huber-Morath, 1978;Davis et al, 1988;Karavelioğulları, 2012).The endemism ratio of the genus is very high, with 202 endemic species (80%). (Huber-Morath, 1978;Davis et al, 1988;Karavelioğulları, 2012;Karaveliogulları et al, 2014;Firat, 2022).…”

Verbascum globiferumHub.-Mor. and V. lysiosepalum Hub.-Mor.are endemic to Turkey which is a center of endemism for Verbascum species. This study gives the anatomical, palynological and seed micromorphological features of V. globiferum and V. lysiosepalumwhich grow in Diyarbakır.The xylem elements occupy a large area in the root cross-sections of the species. In stem cross-sections, the upper part of the epidermis cells is surrounded by a separate cuticle layer and the pith region covers a large area. In the leaves, the main vein is shapped as collateral bundle. Pollen grains are tricolporate-tricolpate, oblate-spheroidal, and exine ornamentation is reticulate. Seeds are brown and oblong-ovate to prismatic and alveolate. The seed coat ornamentation is irregular with polygonal cells, with densely, distinct vesicles.The capsules are pubescent, covered with stellate and branched hairy or glandular hairs.The seed displayed that substantial taxonomic understanding can be acquired from examining the seed characteristics of Verbascum, particularly at the species level.

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 x calcicolum Hub.-Mor., V. x kotschyoides Hub.-Mor., and V. x 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 Woodhouse method, pollen and seed 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 species. The results of this study showed that morphological features, such as pollen shape, polar axis length (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.

In this study, the anatomical, palynological, and seed micromorphological traits of two Verbascum types found in the Southeastern Anatolia Region were investigated. V. sinuatum subsp. sinuatum var. adenosepalum Murb. and V. sinuatum subsp. sinuatum var. sinuatum L. are these variation. Cross-sections from the taxa's roots, stems, and leaves were viewed under a light microscope for anatomical study. The xylem components play a significant role in the taxonomic root portions. The pith area is a broad region in stem sections, and the upper portion of the epidermis cells is encircled by a distinct indented cuticle layer. The leaves' primary vein is represented by open collateral bundles. Pollen grains in Verbascum sinuatum subsp. sinuatum var. adenosepalum are tricolporate-tricolpate, prolate-spheroidal, and have reticulate exine ornamentation. Similarly, pollen grains in V. sinuatum subsp. sinuatum var. sinuatum are tricolporate-tricolpate, prolate, and have reticulate exine ornamentation. The brown seeds of V. sinuatum subsp. sinuatum var. adenosepalum and V. sinuatum subsp. sinuatum var. sinuatum have an alveolate, deep and wide posterior region, a truncated beak, and a prismatic-oblong shape. The ornamentation of the seed coat is made up of irregular polygonal cells that have noticeable and dense vesicles. The importance of a few traits in the Verbascum variety delimitation has been investigated in this study. For the purpose of supporting ancestral traits in the infrageneric classification and helping with genus systematics, some pollen and seed characters which are typically connected to pollen and seed micromorphological and anatomical patterns can be applied.
