Abstract
Dianthus multiflorus from Gazipaşa (Antalya), south Anatolia (Turkey), is described as a new annual species with verrucose calyx. The morphological differences from the species within the same group with Dianthus multiflorus, which are Dianthus aydogdui, Dianthus cyri and Dianthus tripunctatus, are discussed. The International Union for Conservation of Nature (IUCN) threat category and observations on the ecology of the populations are noted. The karyology and seed micromorphology of Dianthus multiflorus and Dianthus tripunctatus were examined by light microscopy and scanning electron microscopy.
Highlights
Amongst all its neighbouring countries, Turkey is the richest in terms of plant taxa, being home to 9996 plant species (11707 taxa) (Güner et al 2012)
With the recognition of Dianthus multiflorus as a new species, there are four annual species of Dianthus, (D. multiflorus, D. tripunctatus, D. cyri and D. aydogdui) that can be separated from other annual Dianthus species on the basis of their verrucose calyxes in Turkey
Our study showed that the shortest chromosome length for D. tripunctatus is 0.77 μm, the longest is 1.21 μm, and total haploid chromosome length (THL) is 14.09 μm
Summary
Amongst all its neighbouring countries, Turkey is the richest in terms of plant taxa, being home to 9996 plant species (11707 taxa) (Güner et al 2012). Hosting 773 of the country’s endemic species Amongst these endemic species, about 244 are best described as locally endemic, being found only in Antalya (Deniz and Aykurt 2014). After Silene L., Dianthus L. is the second largest genus of Caryophyllaceae. This genus, containing approximately 300 species, is mainly distributed in the Mediterranean region of Europe and Asia (Reeve 1967; Bittrich 1993). Among the annual Dianthus species recognized by Reeves (1967), there are only two species (D. cyri Fisch. & C.A.Mey. and D. tripunctatus Sm.) that have a verrucose calyx
