    I think I have been told that Schomburgkias "are now Cattleyas". I am unrepentant, and stick to the old name for two reasons. Firstly, all the famous DNA work only uses a tiny portion of the complete DNA of a plant -having read up on cellular biology I have the strong impression that they use the plastid DNA which is separate from the chromosomes, , is always provided by the seed parent only, not the pollen parent, and amounts to less than 0.1% of the DNA. The claim that this is conclusive seems to me to be highly overblown, and goes unchallenged simply because so few people know anything at all about cellular biology. Secondly, even if it were right , to throw out the Schombo ( in the case ) name, and call it a cattleya, that throws away so much horticultural information. Tell me a plant is a schombo, and I will know it looks different from cattleyas, grows different too, and I'll know how to grow it as well. All that is lost by following this fad from Kew and other labs.
    Rant over. IN South America, e.g. Venezuela I have seen these schombo species with great heads of far more flowers than this , arranged like a giant football ; most impressive. I don't have their climate in Southern England, and am glad to just flower them ( easy, hung up in the best light I can give) but then I sometimes get something which I don't think they get in Venezuela - the flower spike keeps elongating, and instead of 50 flowers all out at once, I have a dozen flowers out, and as one fades, another opens, for months and months...
    Flower colour here the best ever for me , probably due to a wonderful Summer. An English summer, and just 3 mm of rain in 3 months- wall to wall sunshine day after day , mid-day shade temperatures up to 26... unimaginable, but true .Global warming ? The latest wobvble in the Milankowicz cycle., - whatever, I'm just enjoying it.

    beautiful blooms, when I first moved to Florida over 30 years ago, lots of homes had Schombo's growing in trees, sad to say it's rare to see one now

    I am with you on the name change. What next? Doritis is a Phalaenopsis? Ooops...

    The diversity of your orchid collection never fails to impress. Without debating the validity of the type of DNA analysis used in such determinations, I think you will find that it is not the case that Schomburgkia has become Cattleya though.

    At least as far as Kew is concerned, the former Schomburgkias that are typically associated with ant colonies using the hollow pseudobulbs as condos are now in the genus Myrmecophila. Yours is one of these, I think. The distinction between the ant loving types and the other former Schomburgkias has long been recognized and isn't controversial. The genus Myrmecophila for these was first proposed at least as long ago as 1917, though some were called Cattleya or Epidendrum long before that.

    The other former Schomburgkias got merged into Laelia. This close relationship was also long recognized and not controversial. Laelia was proposed for some of these at least as long ago as 1840, though some were Cattleya or Epidendrum at times too.

    So overall the change recognizes the very close relationship of some of them with Laelia, and the distinct nature of the ant condo genus Myrmecophila. You don't have to agree with any of that of course, but it ptobably reflects the consensus for now, and was proposed long before DNA evidence was used to support it.

    Beautiful, I have several varieties. Can you go into your culture a bit more? I have a large one that I cannot get to bloom. I can't imagine its a light issue. I grow outside here in Houston, Texas. Very humid and very hot most of the year. It gets full sun until about 1 and then its dappled and the temps outside are in the mid to upper nineties.
