Seed Morphology Of Some Silene L. (Caryophyllaceae) Species Collected From Turkey, Mehmet Yaşar Dadandi, Kemal Yildiz
Seed Morphology Of Some Silene L. (Caryophyllaceae) Species Collected From Turkey, Mehmet Yaşar Dadandi, Kemal Yildiz
Turkish Journal of Botany
The seed micro- and macromorphology of 39 Silene taxa were studied by stereomicroscope and scanning electron microscope. Quantitative (9) and qualitative (11) values of seed characters vary greatly both within and between taxa. The tree topology of UPGMA based on quantitative values does not supported the traditional relationship. Therefore, we concluded that seed characters of Silene alone cannot be used to describe taxa without detecting the full range of intra- and intertaxon variation of those characters.
Micromorphological Characters On Nutlet And Leaf Indumentum Of Teucrium Sect. Teucrium (Lamiaceae) In Turkey, Gülay Ecevi̇t Genç, Taner Özcan, Tuncay Di̇rmenci̇
Micromorphological Characters On Nutlet And Leaf Indumentum Of Teucrium Sect. Teucrium (Lamiaceae) In Turkey, Gülay Ecevi̇t Genç, Taner Özcan, Tuncay Di̇rmenci̇
Turkish Journal of Botany
Leaf indumentum and nutlet surface micromorphology of 13 taxa belonging to the Teucrium sect. Teucrium was studied with a scanning electron microscope. We observed 5 trichome types on the nutlets and 8 trichome types on the leaves. Branched trichomes were not found on the nutlets. Nutlet shapes of the taxa were elliptic, obovate, oblong, or rotund, and their surfaces were generally alveolate with different ornamentations. Some nutlets had longitudinal ridges. The indumentum varied among unrelated species and showed some significant similarities within related species. In Flora of Turkey sect. Teucrium was divided into 2 groups according to leaf fragmentation and …
