A Taxonomic Study Of The Silene Sections Behenantha And Dichotomae (Caryophyllaceae) In Turkey Based On The Micromorphology Of Their Seed And Pollen, Mehmet Kuh, Kemal Yildiz, Ersi̇n Mi̇nareci̇

The seed and pollen grain micromorphologies of 10 taxa of the Silene sections Behenantha and Dichotomae (Caryophyllaceae) were analyzed in this study. Although the seeds of the analyzed taxa were generally reniform, S. tenuiflora and S. koycegizensis from the section Behenantha were clearly distinct from other taxa, while subspecies of S. dichotoma and S. euxina in the section Dichotomae showed differences. Pollen grains are periporate and spheroidal and ornamentation is generally spinulate-microperforate in all taxa. However, ornamentation is spinulate in S. euxina and semireticulate in S. koycegizensis. While the exine structure is generally tectate, it is semitectate in S. koycegizensis. …


Micromorphological Studies On The Genus Lotus L. (Fabaceae: Loteae) From Egypt, Momen Zareh, Ahmed Faried, Nashwa Farghaly Jan 2017

Micromorphological Studies On The Genus Lotus L. (Fabaceae: Loteae) From Egypt, Momen Zareh, Ahmed Faried, Nashwa Farghaly

Trichomes, epidermal cell features, and seed coat sculpturing of 12 Lotus taxa from Egypt were studied using scanning electron microscopy. In addition, statistical analysis for the taxa under investigation was carried out. The results revealed that trichomes have high taxonomic significances between studied taxa. Anticlinal and periclinal cell walls and epidermal cell shape for the stem, leaf, and calyx for each taxon were examined. Seed coat sculpturing exhibited 4 main different surface patterns categories: rugose, reticulate, sulcate, and verrucate. These features can serve as good diagnostic characters at the species level of the genus Lotus.
