    These two are very alike but there are some differences that can be distinguished.

    My hunch is that they are different clones of the same species. And while I am not very familiar with Oncidium species, my searching through orchidspecies.com leads me to believe that these could be O. baueri.

    The ornamentation around the stigma and the teeth on the callus may be significant in the ID of this species. Hmm... I wonder where I put that Oncidium species book...

    I found something very similar to the flower in the lower photo on page 70 of the Pictorial Encyclopedia of Oncidium. Unfortunately and quite frustrating, it is labeled, "Oncidium species".

    Like I said Marni, I'm not so familiar with Oncidium, but identifying orchid species is quite enjoyable and interesting for me. I guess it's time for me to hit the books! But first, to get some books...

    Oncidium baueri has a long and very confusing taxonomic history, it has been described by dozens of names in many different places. It is supposed to be the same species as Onc. altissimum.

    I've been friends over the years with some taxonomists and have learned that a few things are crucial: patience, a good library, and a mind with the ability to categorize. I lack two of the three and have only a moderately good library. Identifying species can be like a treasure hunt or a mystery and can be very exciting and satisfying. You obviously like it and that is to be admired.

    Without getting you any closer to an identification, a couple of comments:
    Onc. altissimum is not a synonym for Onc. baueri; the synonym is Onc,. altissimum var. baueri. (per Kew)
    While not necessarily part of the taxonomic systematics of a genus, the vegetative habit and inflorescence are useful in identifying a species after the fact.
    Sharper photos from several different angles would be helpful.

    Good luck.

    How long and how distributed are flowers on spikes?
    I have pictorial enc. ilustrated by H. Zelenko, well they both belong to sphacelatum group (in Jay most likely to section: Oblongata), and this one with whiter keels pretty much match Oncidium sphacelatum, but in this book half of the flowers which are by the way painted in natural size, are described just as Oncidium sp... and this rather will stay, quite many sp are very alike...

    If you refer to pic #13 the flower to the left dosent have the cap while the flower to the right has it. Both of this flowers are from the same plant, the flower to the right opened recently while the other has more time opened.

    Both plants started to open their flowers on July. The flowers on pic # 13 & #12 started to open around mid of July. How distributed they are well then I'll have to take photo of that tomorrow ;) jeje
