    I was convinced that the flowers of this species are like those of pumila with a pointed label, while the flowers of the leading cristata have double pointed label.

    Sunday I showed the photo to an expert and he argues that this is not the cristata, cristata the fact that I know I have the largest flowers like this

    Is it really Trudelia alpina ?

    I checked 3 references for alpina and none of them look like your plant. The lip is not forked in any of them. 2 of them show the end of the lip as U shaped or gently squared (that one may just be the angle). I have one other book I was looking for, I hope I didn't loan it to someone.

    It is not Trudelia alpina. The real T. alpina has irregularly dentate leaf tip. The flowers are about 2cm wide, not widely open and nodding. Also, T. alpina doesn't have horns at the tip of the lip.

    I think yours is T. cristata. T. cristata has tridentate(3 toothed) leaf tip. The lip of the flower (color and form) varies from plant to plant, but they all have horns at the tip of the lip.

    It is possible but it is not very likely. If it is a primary cross, I can't imagin what the other parent would be.

    Hi all!

    alpina does not have horns at on the lip.
    Your plant is most likaly a cristata.

    This is definetly Vanda cristata. The size of the flowers, number of flowers, and lobing at the lip apex are highly variable. Related species, mostly from Bhutan, are quite distinct. Vanda alpina is a tiny flower less than 1/2 the size of yours.
