A Numerical taxonomic study on the family plumbaginaceae in Turkey

Erdal, Jelena
The aim of this study was to make evaluation of existing structure of Plumbaginaceae in Turkey in order to see infrafamilial grouping as well as infrageneric arrangement of the big genera (Limonium and Acantholimon). For this purpose, numerical taxonomic method and clustering analysis were used. Also, this was the first time that all the genera of Plumbaginaceae found in Turkey were examined together, within the same study. Herbarium specimens of 61 species were evaluated on the base of 57 morphological characters to construct data matrix. Data matrix was analysed by Multi Variate Statistical Package (MVSP) software. First, Unweighted Pair Group Method with Arithmetic Mean (UPGMA) analysis was used to construct phenograms. Later, Principal Component Analysis (PCA) was performed to indicate which characters were the most significant for the outcome of the analysis. Obtained results were discussed, and compared with previous findings. According to UPGMA phenogram, the genera in our study were well separated from one another, exhibiting quite natural structure. Plumbago and Ceratostigma formed one cluster that correspond to the Plumbaginoideae subfamily. The other cluster analogous to subfamily Staticoidea was formed by Goniolimon, Limoniopsis, Armeria, Psylliostachys, Acantholimon and Limonium. Within genera Acantholimon and Limonium clusters equivalent to the main sections were observed. Furthermore, it was seen that our findings were largely supported the taxonomic treatments given in the Flora of Turkey and the subsequent revisional studies. Eventually, a new generic identification key for the Plumbaginaceae in Turkey including the newly recorded genus Psylliostachys is provided.
