Morphological and Anatomical Aspects of Psephellus pulcherrimus (syn: Centaurea pulcherrima var. freynii) (Cardueae, Asteraceae) Growing in Turkey

Abstract

In the Turkish Flora, it had been mentioned that C. pulcherrima Willd. var. freynii Sint. was poorly known endemic taxon. Then this taxon was transferred to the genus Psephellus Cass. according to recent studies and named as Psephellus pulcherrrimus (Willd.) Wagenitz. In this study, the examined taxon was collected from type locality, the first name was mentioned, and morphological and anatomical characteristics were investigated in detail. All anatomical structures including transverse sections of the root, stem and leaf, and surface sections of the leaves were illustrated. Sclerenchymatic cap in the phloem part of vascular bundles of stem and isobilateral lamina and amphistomatic type stomata were detected in the leaf. Numbers of stomata per 1 mm2 in the leaf surfaces were calculated. In addition, general appearance of the taxon taken in its natural habitat is presented as well.

Türkiye’ de Yetişen Psephellus pulcherrimus (syn: Centaurea pulcherrima var. freynii) (Cardueae, Asteraceae)’ un Morfolojik ve Anatomik Özellikleri

Abstract

Türkiye Florası’nda C. pulcherrima Willd. var. freynii Sint.’den detaylı olarak bilinmeyen endemik bir takson olarak bahsedilmiştir. Daha sonra yapılan çalışmalarla bu takson Psephellus Cass. cinsine aktarılmış ve Psephellus pulcherrrimus (Willd.) Wagenitz olarak adlandırılmıştır. Bu çalışmada incelenen takson ilk adının bahsedildiği tip lokalitesinden toplanmış ve taksonun morfolojik ve anatomik özellikleri detaylı olarak incelenmiştir. Kök, gövde ve yaprak enine kesitleri ve yaprak yüzeysel kesitlerini içeren tüm anatomik yapılar resimlendirilmiştir. Gövde iletim demetlerinin floem kısmında sklerenkimatik şapka, yaprakta isobilateral lamina ve amfistomatik tip stoma tespit edilmiştir. Yaprak yüzeylerinde 1 mm2’deki stoma sayıları hesaplanmıştır. Ayrıca doğal habitatından taksonun genel görünüşü de sunulmaktadır.
