beautiful picture. I personally use the WSCF for checking names.

In
Ophrys they use the monograph by Pedersen & Faurholdt, which is not perfect BUT it is an island of sanity in an ocean of nomeclatural inflation...
The name ''
Ophrys oestrifera'' should not be used for scolopaxoid
Ophrys. This name is a synonym of
O. apifera. I can not locate the type specimen, however the protologue:
http://www.biodiversitylibrary.org/item ... 8/mode/1up
states that petals are very short and hirsute (''petalis interioribus subulatis brevissimis villosis'') a character of
O. apifera. This is why the WSCF has ''
O. oestrifera'' as a synonym of
O. apifera.
To me this is
O. scolopax ssp.
cornuta in accordance to Pedersen and Faurnholdt. It is a very variable taxon, however when you meet it in Greece together with
O. scolopax ssp.
scolopax the differences are striking.
However, the flower does have some intermediate features with
O. scolopax ssp.
scolopax (i.e. the speculum occupies the upper half of the lip, the shape of the lip is not as convex as one would expect) and without measurement it is difficult to judge. O. scolopax from seed are very very variable.
That said, the name ''
Ophrys mattinatae'' is considered by WCSF a syn. of
O. scolopax var.
bicornis. I cannot locate the protologue but according to IPNI there is a copy of it here
http://www.biodiversitylibrary.org/item ... 0/mode/1up
and it talks about horns the length of the lip, curved towards the end point (... labii fere longitudine, acutum, deorsum curvatum),
so I would go with the name
O. scolopax v.
bicornis.
