Campanula quercetorum subsp. densiflora: A New Taxon of Campanula (Campanulaceae) from Eastern Anatolia (Türkiye)

Abstract

Türkiye is a crucial country for the genus Campanula diversity in the Mediterranean Basin. Also, more than half of Campanula species in Türkiye are endemic. In this paper, Campanula quercetorum subsp. densiflora (Campanulaceae) is described as a new subspecies from Tunceli (Türkiye). According to its morphological features, it belongs to the Campanula subgen. Campanula sect. Rupestres. This section mainly consists of perennial polycarpic or perennial monocarpic and chasmophyte species. It is morphologically closely related to C. quercetorum subsp. quercetorum. It is easily distinguished from C. quercetorum subsp. quercetorum by its dense inflorescence, dense indumentum, densely hairy corolla surface, conspicuous purplish-blue corolla veins, and ascending to erect habitus. Diagnostic characteristics, a full description, and comprehensive photographs are given in this study.
