- Cytisus supinus subsp. eriocarpus (Boiss.) Stoj. & Stef., Fl. Bulg. 2: 624 (1925) - Chamaecytisus eriocarpus (Boiss.) Rothm. in Feddes Repert. 53: 144 (1944).

Type.

Turkey. İzmir Province: "Tmolus ad Bozdagh", 06.1842, E. Boissier (K 000829776, lectotype designated by Gibbs (1970: 17); isolectotypes BM 000630427, E 00296045, GOET 005097, K 000829774, KW, LE 01207308, 01207311, 01207312, MEL 2347576, NY 01843146, P 02952858) .

Distribution.

Asiatic Turkey. European records ( Cristofolini 1991; Barina et al. 2018) may be erroneous due to the synonymisation or inclusion of C. absinthioides and C. frivaldszkyanus .

Notes on taxonomy.

This species is very similar to C. frivaldszkyanus due to its abundant patent pubescence. However, it differs from the latter in its broadly elliptic to obovate, nearly rotund leaflets, which are apically subrotund (vs. elliptic-lanceolate to obovate, broadly acute in C. frivaldszkyanus ). Cytisus eriocarpus is similar to C. hirsutus , from which it differs in its pubescence (abundant short hairs mixed with long patent hairs vs. only long patent hairs in C. hirsutus ) and smaller subrotund leaflets, as already noted in the protologue ( Boissier 1843).

Notes on nomenclature.

Gibbs (1970) inadvertently designated a specimen at K as the lectotype of C. eriocarpus .
