Abstract
A new species of Anthyllis endemic to central Apennine growing in dry pastures on limestone in the montane belt, within Abruzzo and Lazio administrative regions (central Italy), is here described and illustrated and the IUCN assessment is proposed. This new species belongs to the morphologically very variable Anthyllis vulneraria species complex and it is close to A. pulchella (south-eastern Europe and Caucasus), but it can be clearly distinguished by its smaller flowers, mainly light yellow-coloured, bracts longer than flowers, calyx pink-coloured (usually only at apex) and size of cauline leaves and leaflets. Furthermore, the name A. pulchella is here lectotypified, by a second-step typification, on a specimen preserved at PAD.

Anthyllis apennina F.Conti & Bartolucci, sp. nov.
Diagnosis: Anthyllis apennina differs from A. pulchella by the bigger cauline leaves and leaflets, leaves evenly distributed along the flowering stem vs. concentrated in lower half, higher number of inflorescences 2–5(–10) vs. 1–2, smaller flowers with standard (7.9–)8.5–9.9(–10.3) vs. (10–)10.4–13.6(–13.8) mm long, longer bracts (12–)14–23(–26) vs. (5.8–)6.5–11(–12) mm long, longer than flowers, with longer lobes (10–)11–21.5(–24) vs. (3.2–)3.9–7.5(–9) mm long, narrowly triangular and acute to apiculate vs. more or less parallel-sided and obtuse and by the colour of flowers which are mainly light yellow or flushed with pink vs. purplish-pink or cream flushed with pink and the calyx which is mainly pink only in the upper part.
Etymology: Anthyllis apennina is named after the Apennine to which the species is endemic.
Habitat: Pastures in montane belt from 1200 to 1800 m a.s.l.
Distribution: Central Apennine in Lazio and Abruzzo (Fig. 1).
