    A karyotypic study on Silene, section Siphonomorpha species of Turkey
    Yildiz, K; Minareci, E; Cirpici, A; Dadandi, MY
    Karyology of the eight taxa of Silene sect. Siphonomorpha known from Turkey was investigated. Diploid chromosome numbers and the basic chromosome number of the studied taxa were obtained as 2n=24 and x=12, respectively. A karyotype analysis of the studied taxa was carried out and the chromosome numbers of S. splendens, S. amana and S. phrygia were determined for the first time. The smallest chromosomes were observed in S. fruticosa and the largest in S. italica subsp. italica. Silene splendens showed the highest A(1) index, whereas S. amana had the highest interchromosomal asymmetry coefficient (A(2)). The karyologic results of the study and the analysis of chromosomal morphology of each taxon is presented.

    Comparative morphological and palynological study on poorly known Asperula serotina and its closest relative A. purpurea subsp apiculata
    Minareci, E; Yildiz, K; Cirpici, A
    Morphological and palynological features were examined in the closely related Turkish endemic taxa Asperula serotina and A. purpurea subsp. apiculata. Their morphological features showed very minor difference such as internodes length and the vein thickness of leaf, however, the seed and pollen characteristics clearly appear to have taxonomic value. The clavate-reticulate seed surface suture of A. serotina clearly differs from that lineate-sulcate of A. purpurea subsp. apiculata. Similarly, the pollen perforations and number of spines differ in each taxon. Moreover, the two taxa are geographically isolated from each other. Ecological features are also briefly discussed. The seed and pollen micromorphological properties could be used for intra/interspecific classification of Asperula which is taxonomically critical.

    Seed morphological studies of Silene L., from Turkey
    Yildiz, K; Cirpici, A
    The genus Silene L., (Caryophyllaceae) from Turkey have been studied for their seed morphology. A total of 19 species of which 3 are endemic belonging to 12 sections were studied. The seeds show variation in their morphology. The seed morphology as studied show section specific observations.
