Orchis purpurea f. albiflora

Posted by
Johan Dierckx (Wijnegem, Belgium) on 28 May 2010 in Plant & Nature and Portfolio.

Series: European Terrestial Orchids

Another Orchid specimen I found on my trip to Germany last saturday. This specimen of Orchis purpurea is also lacking color (like the two species I showed previous days.) I only found one white-coloured specimen in a population of hundreds normally coloured ones. The normal colouring can be seen in my picture of 19 May.

Prachtig shot, bijna een schilderij. Volg je trouwens ook de Elisabeth wedstrijd?
Ik zit iedere avond te kijken! Groetjes van Leonie.

@Photome: Fotograferen is dan ook schilderen met licht ... (heb ik ooit ergens gelezen).
Ik volg de wedstrijd vanaf de zijlijn (denk dat het enkel digitaal te volgen is en mijn tv is nog uit het pre-digitale tijdperk). Hoop dat de Nederlandse kandidaat een mooi resultaat kan behalen ...

Het blijven mooie planten!

@Ralph: Zeker weten ! En hun zeldzaamheid maak ze ook nog eens extra bijzonder.

Er zijn toch wel zeer veel verschillende soorten orchideeën te vinden! (als je er naar zoekt;-) Je etaleert ze hier stuk voor stuk fantastisch en wat ik zo mooi vind: bij het aanklikken van je portfolio springt de hele serie je in één keer tegemoet...heel indrukwekkend:-)

@♏arleen: In België en Nederland samen kom je tot ongeveer 45 a 50 soorten (afhankelijk van wat je als soort/ondersoort ziet). In heel wat openbare plaatsen zou een poster moeten hangen van de KNNV over de Nederlandse orchideeën. We hebben die samen met de WEO (Werkgroep Europese en Mediterrane Orchideeën) opgemaakt. (Er staan trouwens ook enkele foto's van mezelf tussen :-) ) Wie weet kom je die poster wel eens ergens tegen ...

Okay now that one in the front has eyes ;) This is the Matrix, the population is plugged into the hive. My imagination runs wild with your photos and I should be commenting on how they look not.. my strangeness, hehe. I am definitely starting to see the differences and the similarities between types of orchids. I don't think I would remember anything if asked but if I saw them I would certainly know what they are! Thanks!

@Dutch: Just keep on being strange then... I like these comments and imagination ....
Thanks for all the extensive comments again, Kristen !

Part of the flower has a yellow tint to it. What causes that? I think it helps to give the whole plant some contrast.

@Julie Brown: It is just due to the lack of anthocyanines, the pigments that gives the flower its normal purple colouring. The "hats" on the flower are normally brown - that is a mix of purple pigments with yellow pigments... When the purple is missing, the yellow pigments remain. These yellow pigments are xanthophylls, pigments from the carotenoid group. (The same process can be seen in the yellow Ophrys insectifera I posted before.) The lips of this species are usually pure white with some touches of purple. So when the purple pigments are missing in the lip, the white remains.
For the whole flower: the purple pigments are lacking, the other pigments remain.
(I hope I can make you understand, for me it is hard to explain this in English :-) )

Julie Brown from Indianapolis, United States

Johan, I really appreciate the information that you provide with your photos. I think the variety of color found in nature is fascinating and I am interested in the science behind it. I think you do very well explaining this in English, and I do understand what you are saying.

@Julie Brown: I'm glad I could explain.
