    I photographed this Stelis in the wild, in the Atlantic Rainforest of southern São Paulo State in Brazil. The altitude was 650m, and it was blooming in September. Is this really Stelis porchiana or something else?

    I just checked the Icones Pleurothallidinarum index compiled in 2011 and don't find it listed so can't help that way. I can ask a friend if there is a sheet for this species. I didn't see it listed on Orchidstudium in the checklist either.

    Maybe it has a different species name?

    In my opinion, Stelis is an agonizing Genus to differentiate. I found this after a search. Not sure if its what your looking for, but hopefully it leads you in the right direction.
    Stelis porchiana is listed as a synonym of this species on a German species site and IOSPE.

    Amazing? Do you find many orchids in the wild there? We don't have places like that here. That would be an experience to be able to view them this way.

    Not sure how many orchids like this you try to get identified, but if you are hoping for a firm identification rather than an educated guess you would need to provide a close-up of the flower facing directly at the camera and probably also a quarter angle and the side. The lip and its relationship to the column are critical. Especially with something like a stelis that is a small flower and a huge genus you need good images with a lot of detail. I had asked a friend to look at it, but with the odd angle of the flower and the lack of detail there wasn't much that could be done. Since you are collecting plants, there is no guarantee that it isn't a new species unless you really have good images.

    Marni, an educated guess would be good enough. I understand there is still much to be done in taxonomy of varied rainforest orchids (and many other plants, animals, etc).

    Julie, yes we do see a lot of orchids in these rainforests. Pretty much almost any suitable branch or trunk will have many species. I'm just starting to learn orchids though, my main thing are birds.
