This Italian endemic is a member of the small O. lunulata group which was first described from Foggia
by Danesch and Danesch in 1971. Its name refers to the
promontory of Mount Gargano where this species is at its most frequent, although it should be stressed that nowhere within its range is at all a common orchid.
O. promontorii has a central peninsula Italy distribution and may be encountered from the Abruzzi region in the north, down through the eastern provinces to Brindisi in the south. As already mentioned,
its headquarters is firmly the Gargano
peninsula where it prefers short grassland and meadows on alkaline substrates up to approx 1300m.
This is a relatively stable Ophrys although an enthusiastic hybridizer with several recognized and named forms IE :- O. promontorii x O. bertoloniformis = O. azurea ; O. promontorii x O. incubacea = O. angelensis . There is considerable expert debate as to the origins of this species and whilst Delforge
doubts any hybrid heritage, many others are completely convinced
of this. The precise identity of the
contributing species is however a matter of some
disagreement with O. incubacea, O. lunulata and even O. garganica being suspected.
Notwithstanding hybrids, this species is not easily confused with other species and generally presents many stable features. It is invariably green sepalled and hirsuit with basal swellings that are hairless on the inner face. The speculum can however vary from a full glossy blue shield to an H formation and most commonly, two or more isolated dots or streaks.
