Two Different flower in one spike of Phal
 

One thing is astonished me. Today morning I saw two deferent types (actually different colour shaded) flower in a single spike of a phalaenopsis plant. I have no previous experience like this. So I think about it and one crucial point is knocking my mind – I purchased this plant 4th February 2013 from a reseller who imports this plant from Bangkok. The plant was then with two flower buds. When I brought it in my house the season was let winter and temperature was below 120 C. at day time. One bud flourish then which was dark in colour. The second one opens its petal today and now hare the temperature raise 33.90 C. at day time. So is there any possibility for this type of colour change as a result of temperature and light changes?
Here I attached some photos.

Absolutely! Color expression is definitely related to temperature and light levels.

:wavingThanks Ray, Thanks for your answer to influence my weak thought become concrete.

If this knocks your socks off, then you should take a look at Dimorphorchis lowii or Dimorphorchis rossii.

Both species are unusual in that each species have 2 very different looking flowers on the same spike.

Seems to happen with slightly higher frequency with harlequin Phals.

Yes, a curious fact indeed. Here's a previous discussion on the subject.

It will be interesting to see what the THIRD bloom looks like!

Are they male and female flowers? Is that why these species have two distinct flowers on the same inflorence?

I have seen harlequin flowers that are kinda different on the same inflorence, but these two are pretty different! That's funny, not surprising tho, b/c one formed under store or greenhouse cond. are gonna b diff. from those formed in a home setting... Still funny to see! :)

abhijit;
I think that the pattern and flower formation that formed under your watch was the correct one (if there is a correct one!!) - no way of really knowing, but you can see the older bloom has the mottling in it, but it is "jumbled" up in the overall coloring, and the formation is somewhat weak looking. The newest flower looks more like what I would expect along with the form of the flower. Perhaps not, but that is the impression I get.
Whether this is the case or not, I can't really say - this is just an impression. I do like the new flower as the color patterning is more distinct and the flower is flatter and more "open" in presentation.
Again, If a third one opens, let us see it.
Thanks for an interesting and educational post!:)
