Abstract Out of 8 species and 15 taxa (including hybrids) of Mentha existing in the flora of Turkey, 8 taxa belonging to 6 species were investigated for essential oils. Of 272 samples collected from 181 stations in northern Turkey, 85 were subjected to water distillation and GC/MS analysis. The taxa investigated were as follows: Mentha pulegium, M. suaveolens, M. aquatica, M. spicata var. spicata, M. longifolia ssp. longifolia, M. longifolia ssp. typhoides, M. x dumetorium, M. x villosa-nervata. The authors discuss chemotypic variations based on the results of essential oil analysis, soil analysis and chromosome counts.

Dianthus goekayi Kaynak, Yilmaz & Daşkin sp. nova (Caryophyllaceae) is described and illustrated from northwest Anatolia, Turkey. It resembles especially D. erinaceus, but differs it by its longer stems, inflorescence with 2–7 flowers, and papillose calyx tube. The stem and calyx of both species were examined and compared using scanning electron microscopy. The geographical distribution of D. goekayi is mapped.

Abstract A new taxon, Linum hirsutum L. subsp. bozdaghense Yılmaz & Kaynak (Linaceae), is described from southwestern Anatolia, Turkey. It is similar to L. hirsutum subsp. oreocaricum P. H. Davis, from which it differs mainly in the shape and indumentum of leaves and in petal color. Diagnostic, morphological, and geographical data are discussed, and a revised key to the subspecies of L. hirsutum is given.

Origanum sipyleum L. is a species that is endemic to Turkey with known medicinal and aromatic properties and with a long historical use in Turkish folk medicine. Micropropagation serves as one possible method to clone and protect O. sipyleum . In this study, nodes, which served as the explants, were cultured on Murashige and Skoog (MS) basal medium supplemented with different concentrations of BA (0.1, 0.5, 1.0 mgL -1 ) and GA 3 (0.1, 0.2 mgL -1 ). Shoots were transferred to MS medium containing different concentrations of IBA (0, 0.5, 1, 1.5, 2, 2.5, 3 mgL -1 ) for root induction. Shoot regeneration, rooting, survival and acclimatization were possible. As many as 85% of nodes formed an average of 6 shoots/node on MS medium supplemented with 0.5 mgL -1 BA and 0.2 mgL -1 GA 3 . Rooting was most successful in 62.5% of shoots on MS medium with 1.5 or 2.5 mgL -1 IBA. Plantlets derived from all IBA combinations were transferred to autoclaved peat and perlite (1:1, v/v) and acclimatized in a greenhouse, with 79.1% survival. This protocol represents the first comprehensive in vitro regeneration protocol for endemic (Turkish) O. sipyleum .
