Karyomorphological studies in seven taxa of the genus Salvia (Lamiaceae) in Turkey

In this study, the karyotypes of mitotic chromosomes were determined of seven taxa of Salvia (Lamiaceae) collected from their natural habitats in Turkey: S. viridis (2n = 16), S. candidissima subsp. occidentalis (2n = 20), S. sclarea, S. ceratophylla, S. chionantha (2n = 22), S. viscosa and S. verticillata subsp. amasiaca (2n = 32). The karyotype formulae were 5m+3sm in S. viridis, 2M+5m+3sm in S. candidissima subsp. occidentalis, 1M+10m in S. sclarea, 8m+3sm in S. ceratophylla, 7m+4sm in S. chionantha, 9m+5sm+2st in S. viscosa, and 15m+1sm in S. verticillata subsp. amasiaca by the karyotype image analysis system. Somatic chromosome numbers ranged from 2n = 16 to 2n = 32. The ideograms were drawn based on centromeric index and arranged in decreasing size order. The present results were compared with the previous cytological studies in the genus.

Cytotaxonomical study in five taxa of the genus Teucrium L. (Lamiaceae)

In this study, karyotypes of Teucrium sandrasicum O. Schwarz, T. brevifolium Schreb., T. divaricatum Sieber subsp. villosum (Celak.) Rech.f., T. flavum L. subsp. hellenicum Rech.f. and T. kotschyanum Poech taxa growing naturally in Turkey were determined. T. sandrasicum is endemic to Turkey. The squash method for preparation was used for chromosomal investigations. As a result, T. divaricatum subsp. villosum has a somatic chromosome number as 2n = 64 while T. flavum subsp. hellenicum and T. kotschyanum have 2n = 32 chromosomes and also T. sandrasicum and T. brevifolium have 2n = 30 chromosomes. The ideograms and detailed chromosome morphology measurements of the species were performed by the use of Image Analysis System (Bs200Pro). The research has made contribution to the taxonomic revision of the genus Teucrium in Turkey.

Contribution to the cytotaxonomic knowledge of 10 species of Klasea Cass. (Asteraceae) from Turkey

In the present study, karyotype analyses of 10 taxa belongs to the genus Klasea Cass. (Asteraceae) were conducted. Somatic chromosome numbers are not a distinctive character of classification of Klasea taxa. All of the taxa were counted as 2n = 30 chromosomes, except for Klasea radiata subsp. biebersteiniana (2n = 60). Although all the taxa have a chromosome number of 2n = 30, they could be differentiated by their karyotype formula and quantitative parameters of the karyotype. Karyotype analysis was performed by means of an Image Analysis System and karyotype asymmetry indices were measured. According to these parameters, karyological relationships among studied taxa were inferred.

Typification of Four Linnaean Names in Centaurea (Asteraceae)

The Linnaean names Centaurea aegyptiaca, C. behen, C. scabiosa and C. verutum (Asteraceae) are lectotypified using three specimens from Linnaeuss herbarium and a Rauwolf illustration. The designations are based on an assessment of Linnaeuss original material.
