Ophrys passionis

O. passionis was first described by Sennen from Barcelona in 1926 and its name refers to the species Easter flowering time. This taxon, together with O. arachnitiformis and their various recognized forms have been much studied over the last decade, this has not however resulted in any consensus as to an agreed nomenclature and species positioning for these Spring flowering, French Ophrys.

This split in expert opinion and failure to come to any unanimity of view, makes it's difficult to present a precise definition of the species involved and consequently until the position becomes clearer, O. passionis, O. caloptera and O. occidentalis are the only taxons capable of being visually and geographically separated. This is however unsatisfactory and requires study at a molecular level, rather than views (no matter how learned) formulated largely on morphological observations. O. passionis has been known for many years and until recently was believed to be a species with two distinct flowering waves, covering a period from mid March through to late June. Current thinking however regards the successive flowering as two very similar but separate species. As already mentioned their is not complete agreement on this point but broadly, the early flowering wave retains the name of O. passionis but is placed in the O. exaltata  group, whilst the later wave have been reclassified O. caloptera and remain in the O. incubacea group.

O. passionis is a weaker, less robust plant than O. caloptera although the flower itself is very similar and it's really the earlier flowering period that serves as a differentiator. It can be in flower by the middle of March whereas O. caloptera does not usually appear until a month later. The pictures come from Bouche-du-Rhone, France and date from the end of March.
