Type.

(neotype here designated): Herbier A. Dubuis, Dianthus subacaulis Vill. subsp. subacaulis, Pentes rocailleuses dénudées près du somment du Mont Ventoux (1912 m). (Vaucluse), 7 July 1955, MPU329773 (photo!).

Note.

No original material was found in GRM and in the other surveyed herbaria. Also A. P. V. Mutel’s Herbarium was checked because he used to include Villars specimens in his own herbarium (M. Lefebvre, pers. comm.).

The neotype designated here matches the protologue and corresponds to the current application of the name, which is accepted by both Kerguélen (1993) and Tison and de Foucault (2014). This species is characterized by having 1 cm long basal leaves, very short, 1-5 cm long single-flowered scapes and epicalyx scales lanceolate with a linear mucro. Concerning the shape of calyx teeth, it is very similar to the lectotype of D. inodorus (L.) Gaertn., which in turn is currently included within the variability of D. sylvestris (Domina et al. 2021). Further research is needed to clarify the relationships between these two taxa.
