INTRODUCTION

Klasea ‌Cass., a genus in the subtribe Centaureinae of the tribe Cardueae in Asteraceae ‌Bercht. & J.Presl (Hellwig 2004; Martins & Hellwig 2005; Martins 2006; Susanna & Garcia-Jacas 2007, 2009), comprises over 65 species that chiefly occur in Europe, the Mediterranean region, southwestern Asia and northern Africa (Susanna & Garcia-Jacas 2007). According to modern taxonomy, the genus includes eight sections in Turkey: Klasea sect. Coriaceae L.Martins, K. sect. Demetria (Boriss.) L.Martins, K. sect. Lasiocephalae L.Martins, K. sect. Klasea, K. sect. Melanolepis ‌L.Martins, K. sect. Leuzeopsis (Boriss.) ‌L.Martins, K. sect. Quinquefoliae L.Martins and K. sect. Schumeria ‌(Iljin) L.Martins (Martins 2006). It has been reported that Klasea contains 15 species in Turkey (Davis & Kupicha 1975; Martins 2006; Dogan et al. 2015). Five of these species are endemic to Turkey, resulting in an endemism ratio of 33.3%. The genus includes unarmed perennial herbs with involucral bracts mostly lacking apical appendages, tubular florets, and glabrous achenes, and a simple, seriate pappus composed of free, long bristles (Martins 2006; Susanna & Garcia-Jacas 2007).

Continuing my taxonomic study of the names in Klasea (Ranjbar et al. 2011, 2012, 2015; Ranjbar & Negaresh 2014; Negaresh 2023), I realized the necessity to lectotypify two species endemic to Turkey, i.e., K. ‌aznavouriana ‌(Bornm.) Greuter & Wagenitz and K. bornmuelleri ‌(Azn.) Greuter & Wagenitz, because no specific herbarium sheet was cited as holotype in their protologues and the taxa were also not lectotypified earlier (Davis & Kupicha 1975). Following a thorough examination of the literature and of the type material, lectotypes are designated here for these taxa.

Remarks

Bornmüller (1906) indicated the type of Serratula ‌aznavouriana (Klasea ‌aznavouriana) as ‘Anatolia bor. Prov. Pontus, in monte Tavschan-dagh prope Mersivan [Merzifon], 1904/1905, Manissadjian’. Pertaining to the type specification provided in the protologue, eight duplicates specimens of Manissadjian s.n. were traced (B100277136, B100277137, B100277138, E00083602, G00012010, G00012011, G00012012, G00012014). According to McNeill (2014), the existence of a holotype cannot be considered before 1990 unless one particular herbarium was indicated in the protologue (and only one specimen of the gathering was deposited there) or if it was made clear that only a single specimen of the gathering existed. Because there was more than one specimen for this species housed in more than one institution, they are duplicates. Based on Art. 40.2 Note 1 (Turland et al. 2018) these must all be treated as syntypes. The sheet B100277137 is selected as the lectotype here because it contains leaves, flowers, and capitula that are better developed than in the other duplicates, and the characters of the specimen agree with the protologue.

Lectotype

Remarks

Aznavour (1912) described Serratula ‌bornmuelleri (Klasea ‌bornmuelleri) based on collections of G.Post & B.Post 30 from Dérindeh, but did not designate a holotype nor did mention the name of the herbarium where the specimens were housed. Three specimens of K. ‌bornmuelleri collected by G.Post & B.Post from Dérindeh were found. Based on Art. 40.2, Note 1 (Turland et al. 2018), these must all be treated as syntypes. Of these, the sheet G00012017 is better preserved and more complete than the other specimens, and best represents the species description given in the protologue; hence, it is designated here as the lectotype.
