573 Orchis purpurea Huds.

This mainly C. and S. European, calciphilous species is lacking in same parts of the range. It is labelled as a Mediterranean-West-Pontish species in Hegi 2 (ed. 2), p. 447, and may perhaps be regarded as a southern counterpart to O. militaris (no. 574). Cf. also Meusel et al. 1965, map. p. 109.
