Nomenclatural note. The type collection of V. caespitosa is similarly complex. Boissier (1844) mentioned two collections, his own collection from Mt. Cadmus (Madran Mountain) and the one from Aucher-Éloy from Mt. Olympus in Bithynia (Uludağ), likely collected in 1833 ( Baytop 2005). Both collections are present in several herbaria. Overall, I found 12 specimens of Boissier and eight of Aucher-Éloy. Since Boissier is more likely to have relied on his own collections, the lectotype is chosen from his collection and the Aucher-Éloy collection is considered to be the syntypes. Most of the specimens of Boissier’s collection have the same yellow label “Boissier 1842 – Cadmus supra Gheyra et Olympia” and are the ones distributed by Boissier to other collectors and herbaria. An exception is the one in the herbarium Bentham (K001070299), which states only “Cadmus” and was likely, similar to the specimen of V. cariensis , sent to Bentham before shipping of the other specimens. The best specimen is found in his own herbarium with the label “Pic de Gheyra pais superior, Cadmus occid. Junio 1842 ” but not explicitly stating V. caespitosa . Nevertheless, it is clear that this is the species described by Boissier.
