Yes it does indeed. I still wait until this and the next flowers develope. Its very tiny, but that could be because of the actual temperatures over here. Just about 3cm NS. There are many pics in the web, but I don't trust much in most of them. According to the pages by bernard.lagrelle and phals.net it could be one or another. There is an isthmus, but it is folded backwards mimicking a very compact lip. And I still don't know for sure what the differences in the appendix of either flower are supposed to be.
And waiting for the scent.
Still not very happy with this tiny flowering.
