    So, this plant came from a certain angraecoid seller in the Carolinas. It was labeled as Aerangis laurentii, which doesn't actually exist and it clearly isn't a Summerhaysia laurentii. Either last year or the year before, I determined based on La Croix's "African Orchids in the Wild and Cultivation", that it is Aerangis confusa. Anyone else have a different opinion? I have included the measurements as well as a couple of pictures. And unfortunately the plant was at its prime last week when I had a house full of guests and I didn't get good photos taken. These photos and measurements are taken from this blooming. I'd love to get someone else to either confirm my identification or maybe identify it as something else.

    Largest leaves are between 14-15cm long, 4.5 cm wide.
    Spikes measure an average of 25 cm and have 11, 8, 10 and 12 flowers respectively
    Flowers average 1.5-2 cm apart.

    Flower measurements:
    Vertical spread 3-3.5 cm
    Horizontal spread 4-4.5 cm
    lip is 1.5cm long and approx 5 mm wide
    column is 5 or 6 mm long
    sepals are 5mm and petals are 3-4 mm wide
    spur is 6cm long

    Oh boy ... I had one of these in years past and it perished under lights before I had a chance to build the greenhouse. Total bummer. Very nicely done.

    Ditto for me. I had one. It is possible I still do. But mine was supposedly 100% ID'd as biloba by Erich of the former Hoosiers. That was via emailed pictures however. And I don't recall it having nearly so much color as yours.

    There were some plants that I saw in situ this summer that were told to me as being confusa, and the leaves were indistinguishable from brachycarpa...more rigid with black spots than your photo, Reyna.

    Well, drat. Hmmm. Calvin and Mike do you have photos of the plants or flowers for comparison? I'm confident this is not a biloba because both the flowers and leaves are markedly different. I could go dig up a picture of biloba -- but you both know what they look like already. :)

    Your plant is most certainly not biloba.

    Yep, clearly not biloba. :)

    After posting, I have gone back to the books and I really think it is confusa. Using La Croix's Key to the Species it clearly comes out as confusa based on measurements and description etc. And it does not match any of the species in the Cribb/Hermans Field Guide to the Orchids of Madagascar -- which would be consistent since confusa comes from Kenya etc. And the description is consisent with the description of confusa in Stewart's in the Angraecoid bible, though there is no key per se for the genus.

    So well-grown and flowered!

    I've bookmarked this conundrum. When I've had some quality time with my books, I'll let you know what I think :)

    We still haven't heard from you how you arrived at confusa as the ID. Come back :)
