Abstract. P. Devillers & J. DevillersÐTerschuren: A systematic analysis of genus Ophrys [Natural. belges (Orchid. 7 suppl.) 75 (1994): 273-400]. The paper attempts an arrangement of genus Ophrys into first, second and, when possible, third and fourth order divisions, with a definition of the limits of species groups and species based on consideration of features resolvable into discrete character states. Some of them have long been known, others were little used in previous analyses.
Key-Words: Orchidaceae, Ophrys, systematics.
