Ophrys drumana 

  This is an orchid endemic to France and which has its headquarters in the southern Vercors area of Drome
 indeed its name means "from Drome".  It has a few other stations in adjoining Provinces such as the    Ardeche, Bouches-du-Rhone and possibly Isere.

  Its a very local orchid but can be frequent in its favoured areas,  and these areas always seem to be a dry
  location in full sun - rocky hillsides, garrigue, abandoned olive groves and light woodland.  Its preferred      habitat is always at altitude though usually in the Alpine foothills between 250 and 1000 meters rather       than in the high mountains.  

  O. drumana is easily recognized as a member of the O. bertolonii group and at up to 40cms is certainly         one of its  more sturdy members. It's also one of the most distinctive species in the group and although it      can be somewhat variable it's not readily confused with any other of its cousins and not least by virtue        of its isolated range. Its distribution is thought to marginally overlap with the similar O. saratoi and            although it may well hybridise, their seems to be no formal record of this having been noted.

  As already mentioned, O. drumana  can be a fairly variable orchid with notable differences in lip shape
  and speculum colour (see the variation between photo's 4 and 10). It can be a tall plant with up to twelve     flowers and is most commonly found growing in small, loose colonies.

  These llustrations are all from the southern Vercors, predominently in the area between Combovin and          Beafort-sur- Gervanne.  They date from the last week of May.
