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. | Turkish Journal of Botany Turk J Bot (2015) 39: 280-297 © TÜBİTAK doi: Research Article Seed morphology of some Silene L.

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. Key words: Micromorphology, seed coat, scanning electron microscopy, Silene 1. Introduction Silene L. belongs to the subfamily Silenoideae of Caryophyllaceae, which consists of about 700 species around the world (Greuter, 1995). The genus is distributed in the northern hemisphere, mainly in Eurasia (Zohary, 1966; Coode and Cullen, 1967; Davis et al., 1988; Melzheimer, 1988; Chater et al., 1993; Tan and Vural, 2000), and is represented by 165 species (Yıldız and Çırpıcı, 2013) in 31 sections (Coode and Cullen, 1967) in Turkey. Some species of Silene form a complex, since they are separated from each other by only small morphological differences, which may intermix or overlap. In particular, anthophore length, capsule length, and leaf width are used to differentiate species on millimetric scales (Coode and Cullen, 1967). Therefore, the identification of these species may be difficult, especially when they
