Terrestrial Orchids 2016

[Steve Garvie]

Your bog orchids are wonderful Gabriela!!!


It's a driech day here but some of the dactylorhiza are glowing through the smirr:

Dactylorhiza fuchsii -two pale flowered plants:



Dactylorhiza fuchsii alba


Dactylorhiza maculata alba

[Tony Willis]

Early July is a second flowering period for orchids in Ontario with Pogonia ophioglossoides in full flower.

The second image is not too great but for the ones interested in growing it in the garden it shows that can be tried like this - in a calcareous meadow-marsh in association with other species (in the image: Lobelia spicata, Polygala senega, Castilleja and others…).

Saw them near Tobermory four years ago together with Cypripdeium reginae ,wonderful

Lovely plants Steve,they seem to be at their peak at the moment

Yes, the Tobermory area and surrounding is good for orchids. I didn't drive that far this time. You must have stayed there for a while though - C. reginae is flowering quite a few weeks in advance than Platanthera. I didn't see them this year, but in exchange catched a small ram's head in flower

 That would be Tobermory, Bruce Peninsula,  Ontario -  rather than the one  in Scotland

Cycling home yesterday I came across a nice varied group of Pyramidal orchids on a main roadside. I have lived in Leeds for the best part of fifty years and never spotted them here before!

That was a great find, Tim.  I wonder if the verge is being cut less than if previous years and that has enabled them to flourish?

[Tim Harberd]

I can't really comment Maggi. Although the site is only 9 miles from my door I don't go that way very often, because the road is so busy! One reason for going that way on Saturday was because of continued road closures following the Boxing Day Floods.. (It's hard to imagine road & rail links in areas South of the [don't laugh] 'Northern Powerhouse' taking SOOOO     L  O  N  G   to repair!)

orchids season ends slowly, in the Cevennes forest hosts several species of Epipactis

Epipactis exilis is very rare in the region



Epipactis atrorubens can be found in beech woods



the common Epipactis helleborine revealed a typical coloring in these forests



In the pinewoods Goodyera thives



the classical Cephalanthera rubra

[Steve Garvie]

Maybe we need a thread for semi-terrestrial orchids:

Calopogon tuberosum



Pogonia ophioglossoides


Disa uniflora


Platanthera grandiflora



Platanthera dilatata -The Bog candle. First time flowering for me.
Mature plants can have an impressive flower spike.

Fine orchids, Yann ; we have only found Epipactis palustris in a peat bog before "Les Saisies" ; a good page  http://orchidees-alsace.hautetfort.com/media/02/02/738968183.pdf

[Gabriela]

All these beautiful orchids and the bug sitting still on Cephalanthera reminded me about this - for those who don't already know:
Studies have shown that Epipactis nectar (also of other orchids) contains chemical substances with narcotic properties. They have a role in attracting pollinators and making them ‘sluggish’ (so that they spend more time on flowers). There is also ethanol involved, which can lead to the ‘drunken insect behaviour’!

Of course these narcotics are present in ‘minute’ quantities, but it was enough to arouse the interest in 'ethnobotanical' circles. A good thing these are not easy to grow species
WHY DO POLLINATORS BECOME “SLUGGISH”? NECTAR CHEMICAL CONSTITUENTS FROM EPIPACTIS HELLEBORINE (L.) CRANTZ (ORCHIDACEAE)

interesting

[Gabriela]

I got proof of the 'narcotics' - the wasp(?) was totally 'stoned' on the Epipactis and only after I touched it gently to make sure was alive, it moved slowly to another flower (not great pictures, I was in a hurry).

The third image with Spiranthes (most probably romanzoffiana) shows the combination between the perfect camouflage and a sluggish insect.

[Gabriela]

It seems the website works better, last night I got stucked on the forum and couldn't log out.
This would be the third wave of orchids flowering in Ontario.
The one with the spider was indeed Spiranthes romanzoffiana, among the first Spiranthes to start flowering. It can be variable in height but with the specific tight spirals of flowers. Not very great looking in this drought year.


A fragile, slender lady Spiranthes lacera (Slender Ladies Tresses). First image shows the very specific overall look, I apologize is not up to the standards of this thread but is very hard to capture it. I don't get to see it every year so...


The detail not that bad. The flowers can be one sided or like here in a large spiral.


Goodyera repens - with variegated foliage. It used to be G. repens var. ophioides but I understand the varieties are not recognized anymore. Yann has posted a beautiful close up.


And the more often seen Goodyera oblongifolia
