Abstract. Delforge, P.- Mr. Philippe's Ophrys [Natural. belges 81 (Orchid. 13) (2000): 111-144 + 8 figs]. Ophrys philippei was described from Toulon (Var, France) by Grenier (1859) and also studied by Moggridge (1869). In 1892, E.G. Camus has considered it as an occasionnal hybrid between O. scolopax and O. sphegodes s.l. The Camus's opinion prevailed till now. Carefull examination of the Grenier's protologue and exsiccata as well as Moggridge's work has revealed that O. philippei doesn't possess characters from the O. sphegodes species group nor the morphological variability of occasionnal hybrids. O. philippei is a late flowering Ophrys scolopax s.l. with small flowers, dorsal sepal sometimes recurved on the connective, and frequent morphological transitions to O. fuciflora, due to the inconstant tendancy to lateral inrolling and the frequent subentire shape of the lip. Personnal research in France, Spain, and Italy as well as examination of the litterature has led to the recognition, in France only, of Ophrys populations corresponding to the Grenier's O. philippei. Its presence is attested in Alpes-Martimes (06) and Var (83), Aveyron (12, Southern Massif Central) and Poitou-Charentes (Charente, 16; Charentes-Maritimes, 17; Deux-Svres, 79), where it is known as O. santonica Math & Melki 1994. A lectotype is choosen for O. philippei and a discussion is made on the affinities with apparently close taxa as O. conradiae (Corsica, Sardinia) and O. picta (Spain).
