Orchid Identification Help
 

To all the orchid enthusiasts,
I received this cutting from a co-worker and she was not certain of the name or genus:dunno:. I believe it is a dendrobium but the name is a mystery. I have researched on-line extensively to no avail. If there is anyone that can give me an exact or just even close to a name it would be much appreciated. Thank you in advance.

Sort of reminds me of some sort of Cattleya rather than a Dendrobium, but I could be completely wrong on that. Hopefully someone more knowledgeable will be able to point you on the right lines.

Thanks Rosie C
The size of The bloom is about the size of a .25cents/quarter very small for a Cattleya but, you never know? I will give that a look and see if I can find something similar. Thanks

Dendrobium crumenatum or a close relative.

Thank you RobS
Grand-slam, I went online and browsed around and bingo there it was and the explanation was exactly right. (The pigeon orchid) is a common name for it.
Thank you for the help

Definitely a Dendrobium, but if the flower is still open, it's not crumenatum. Dendrobium crumenatum flowers only last for a few hours.

Dendrobium, yes. Crumenatum, no.

Kip is right, only a few hours.

Not a full day
 

Thanks everyone,
Your help has broadened my knowledge and I am thankful.
From bud to bloom was at the speed of sound. (Figure of speech) it only lasted that day and by evening it was shriveled up and gone. When I received the cutting it was in not the best of shape all the canes were cut back and now I have mounted them on driftwood and the life is back with new growth, roots and the one bloom. I don't have to be perfect on the name because I will never know for 100% sure. So, a thank you to everyone that helped.
RobS answer is the one I will go with.
Dendrobium Crumenatum (or a close relative)
