Holotypus: GREECE: “In reg. sylvatica m. Olympi Thessaliae”, 22.VII.1851, Heldreich s.n. (G-BOIS [G00332058]) .
= Turritis glabra L., Sp. Pl.: 666. 1753.
Notes. – The original protologue erroneously gave the collection year as 1852 instead of 1851. No duplicate of the type collection was examined. A sheet annotated in Boissier’s handwriting as Arabis pseudoturritis collected by C.N. Fraas (G [G00383992]) is not part of the type collection .
STRID & TITZ (1986: 262) lectotypified the species, but that was unnecessary because Boissier based the species description solely on the unicate in his herbarium. They and TITZ & SCHNATTINGER (1980) recognized this taxon as Arabis glabra var. pseudoturritis (Boiss. & Heldr.) Fiori (Nuova Fl. Ital. 1: 576. 1924). However, the taxon definitely belongs to Turritis (tribe Turritideae) rather than to Arabis (tribe Arabideae). Whether or not it merits recognition at the infraspecific rank is another matter, though the first author feels that it is not sufficiently distinct to be accepted.
