a small white orchid to identify
 

Photo taken in a greenhouse in France. I've no idea about th name of this orchid...can you help me in the ID? Many thanks in advance...

Probably Jumellea arachnantha.

Definitely an Angraecoid.

Must be the ang family, as King said. Here is a site that sells or grows many angs and might provide some visual help.
Orchid Species
The other helpful site, once you have a lead:
Internet Orchid Species Photo Encyclopedia

It looks somewhat like Ang. leonis, but the Ang. leonis flowers have more yellow coloring in the throat and a somewhat different petal shape; but it is close. That spur makes it a good candidate for the Angraecum family though. I definitely think Angraecum is the family you are looking for, and a little more research will probably prove that. BUT, regardless, it is a beauty! Did you catch a fragrance? Many only smell at night, so that may not have been evident when you were present. When it is identified, I hope it is available as I really like it ( of course I never met an orchid I did not like, sooooo.......).
Thanks for posting the pics - I really like the pure white flowers and the strap leaves - very nice!
Thanks again,
Steve

AHHHHH - I think I found it. Good call King-o-orchids - Look up Jumellea arachnantha - I have a link but it is in Russian (I think) - but the photo is in English (ha)!
Try this - Файл:Jumellea arachnantha - Flickr 003.jpg — Википедия
It looks a lot like the overhead shot you have provided. Took a little research (I LOVE research!), and looking at 100's of pics, so now I have a real orc-craving!
Hope this helps.

Many many thanks to all!!!The link in russian (Thank you Steve!) shows an orchid looking really like mine orchid!! Good. So, it must really be a Jumellea arachnantha.

You are very welcome -
At this time I am semi-house bound, needing back surgery AGAIN, so I have a lot of time to spend looking things up; plus I love a challenge such as this. I found another couple of orchids that look a lot like yours, all Angraecums, but the Jum. arachnantha was the best looking match - you can only do so much ID'ing with only pics to go by. I hope you can verify this as the orchid you saw, and as I said, now I want more orchids - of course I am still breathing so that desire is a given!!!!
Happy hunting!
Steve
