[Note Guidelines] Photographer's Note
Dactylorhiza sambucina (Elder-flowered orchid) is a widespread European orchid with a boreal-alpine distribution. The orchid species shows a stable and dramatic flower-color polymorphism, with both yellow- and purple-flowered individuals present in natural populations throughout the range of the species in Europe. The evolutionary significance of flower-color polymorphisms found in many rewardless orchid species has been discussed at length, but the mechanisms responsible for their maintenance remain unclear. The mean frequency of yellow-flowered D. sambucina across natural populations in Europe is 53% 2.6. Any differences did not find between the two morphs for other traits such as plant height or the number of leaves and flower size, and the two morphs are identical for floral scent. (Gigord LD, Macnair MR, Smithson A., 2004)

The photos was made on the same locality in Krusne hory Mountains, but distance between the plants was too long for one shot.

Beautiful presentation Jan! Lovely, sunny, colorful shots. Very informative note. I'm asking as always ;-) - how is orchid in Czech? In Polish we call it Orchidea or Storczyk. Thanks for sharing!

Nice shots! You've captured these two specimens of D.sambucina very well. Nice to see polymorphism so clearly illustrated, and the note explains it well. Technically no significant comments to make, other than maybe a bit less JPEG compression next time - the yellow-flowered shot has noticeable artifacting around the top of the florets. The fact that it's missing on the left hand shot makes me think that maybe a little more DOF would be useful there. I really should get around to uploading some of my orchid shots at some point... Anyway, nice shots, and a useful note - good work :-D
