Variability of Ophrys lucis

Ophrys lucis is one of the most interesting orchids of Rhodes. For orchid lovers who wish to see this species in the field, Rhodes is the ideal place. Here one can see all possible variables of the species fairly easily from mid February to mid March in a variety of habitats. It is a rather rare species forming small populations mostly in the central parts of the island.
Today I present some photographs in order to show the variability of the species.

Ophrys sitiaca. The first Orchid of the season!

Ophrys sitiaca. Filerimos hill

It is like a rendezvous! Every new year, in the first ten days of January, I use to visit the nearby pine woods of Filerimos hill. There, under the shade of pine trees, Ophrys sitiaca is always the first orchid that begins to flower.
Happy New Orchid Year to all!

Ophrys parvula and Ophrys cinereophila, the two small pseudophrys of Rhodes

Left: Ophrys parvula, Kattavia 6-04-2011. Right: Ophrys cinereophila, Attaviros 10-04-2011

They both have a small lip (less than 1cm) with a yellow border around it. How can a non expert identify them? Identification of those two species is not easy but not impossible either.

One must pay attention mostly to the bending of the lip. The lip of Oprhys parvula is almost straight across the longitudinal axis, starting to bend (if at all) just after the 2/3rds of its length whereas the lip of Ophrys cinereophila is bending downwards right from the start, at the basal area.

In general, Ophrys parvula is a sorter plant with fewer flowers than Ophrys cinereophila and usually it is found among phrygana, whereas Ophrys cinereophila can be found in a greater variety of habitats like woods, dry meadows and phrygana.

Of course those two species, as the majority of orchids of the genus ophrys, have a different pollinator. Andrena tomora for O. parvula and Andrena cinereophila for O. cinereophila.

Ophrys parvula was considered endemic to the southern part of Rhodes island but recently Zissis Antonopoulos found similar plants in central Cos and Giannis Gavalas in Iraklia (Small Cyclades). It seems that this species is endemic to Southern Aegean islands.

Ophrys cinereophila is distributed from SW Greece to Dodecanese, Cyclades, Crete, S Anatolia and Lebanon.

?= the presence of the species is under question but there are some evidences for its presence

Ophrys transhyrcana??= an Oriental species, maybe the plants of Rhodes are just a variety of O. mammosa

doubtful= the presence of the species is doubtful and there are some evidences that the report from Rhodes was erroneous

extinct= the species is extinct from Rhodes but there are possibilities to reappear

Cephalanthera epipactoides (extinct?)= the single plant of this species that I have seen on the island has been extinct but there are some reports for the presence of the species.
