Varieties of orchids at Gamone

This morning, once again, I strolled up along the road at Gamone to admire our splendid wild orchids, while attempting to identify as many as I could. In yesterday's blog post [display], I indicated the presence of many Monkey orchids (Orchis simia). I picked a few specimens and brought them home to be photographed. The monkeys in the following specimen have dark purple paws:

In another specimen, the monkeys are pale and slender... and the fellow at the bottom has an erection!


I don't know whether they're two slightly different varieties, or whether the first plant is simply more mature than the second. In the following specimen, probably a Military orchid (Orchis militaris), the form still has arms and legs, but it's more like a woman in a bulky skirt than a monkey:


I haven't been able to identify the following fine specimens, whose flowers have the form of a person wearing baggy pants, but they might be Burnt-tip orchids (Neotinea ustulata):


In various places on the slopes above the roadway, there are entire walls of Pyramidal orchids (Anacamptis pyramidalis).


From a distance, you might mistake each plant for a single flower. But, when you examine them more closely, you realize immediately that each pyramidical head is indeed a group of orchid blossoms.


The larger flowers at the bottom reveal the typical asymmetrical form of each orchid blossom, composed of three small sepals, two small petals and a large third petal, double-lobed, called the labellum.


Finally, the most exotic orchid specimens I discovered at Gamone were members of the Ophrys variety, whose labellum looks like a large insect.


I examined this specimen from every angle, and compared it with photos on the web, in an attempt to identify the exact variety.


I concluded that it could well be an Ophrys fuciflora (Late Spider-orchid), or maybe an Ophrys apifera (Bee Orchid).


Click here to access an excellent website with examples of many wild orchids. Incapable of identifying with certainty my Ophrys specimen, I decided to contact the creator of this website, Philippe Durbin, who's an expert on French orchids. Here's an English translation of his reply:
I can understand your problem, because it's not obvious! I would imagine a hybrid between Ophrys fuciflora and Ophrys apifera. No certainty, however. See if you can find its parents in the vicinity.
Trust me, on my initial orchid excursion, to find a puzzling specimen! Now I'll have to wander back up on the slopes and look around for the mum and dad of this orchid love child. Why couldn't they simply procreate in a hermaphroditical fashion, like most self-respecting Ophrys orchids? Or with the help of a bee, like those queer orchids that get a kick out of bestiality? Maybe the parents of my puzzling orchid specimen had heard of "the good effects of intercrossing" in a book published in 1862 by a celebrated English naturalist.
Charles Darwin: On the various contrivances by which British and foreign orchids are fertilised by insects, and on the good effects of intercrossing.
