    Default Ascocentrum garayi

    Hi,

    this plant came from Thailand and is apparently prone for scale attacks. Jim Cootes was very helpful in identifying it and shared an article with me, which should be of great interest here, as we had numerous discussions about it.
    I may share this paper with permission from the senior author, which came out in Orchids Australia Dec. 1995, page 18-19.

    Cheers!

    I would only argue with the tiny drawing of A.aurantiacum ssp. philippinense, that the midlobe is also curved downwards.

    Thanks Ron for sharing. Very interesting article. I have the Thai 'miniatum' which rightly should be called garayi but I have another 'miniatum' collected by myself many years ago from an area right on the Thai/Malaysian border. This plant has longer slimmer leaves than the Thai variety as per the photo of your plant. As far as I know the area where I collected the plant is the only known place in Peninsular Malaysia to have this Ascocentrum. Unfortunately my plant is barely surviving and has not bloomed the last 2 years.

    However a friend of mine has a few healthy specimens collected from the same area. Here I'm posting pictures of the blooms on his plants and since these pictures were taken in April (spring) I assume these must be garayi? The flowers are smaller than the Thai var and more reddish.

    Ron, Thank you for sharing this enlightening information about Asctm. miniatum and garayi.
    Since you started off by telling us that your plant was prone to scale attack (which can be seen), do you have any idea or information as to why certain Vandas are more susceptable to scale than others. I am aware of how foolish this sounds, but I have seen it in my own collection where one particular plant keeps repeating scale and the others remain untouched.

    Angela - no idea about vanda scale infestations, but I've come across it on some cattleyas growing right next to other catts with no sign of scale whatsoever. I think it's an excellent question, and I wonder further just how much scale can an orchid tolerate before it no longer flowers, or, indeed, survives. Ron's seems to be flowering despite all.

    The confirmed A. miniatum I have seen pictures on and the one plant I have seen in real life have been significany smaller than the A. garayi I have seen!
    The article speak of equal size ... ?

    I am not allowed by forum rules to link to pictures of confirmed A. miniatum but on another forum there is really good pictures on an A. miniatum that is very different from A garayi even in the leaves.

    Hi Yew, thanks for your input and all, and from what i can see your posted pix are of Asctm.miniatum, based on the leaves and i can see the midlobe on some flowers bending downwards. However, i can't see the shape of the spur, and if it's curved forward then i might be Asctm. aurantiacum, confusing eh?
    Asctm. garayi has those typical stout "V-shaped" leaves and see the the midlobe on my pix formed like a "spoon" in a 90 degree angle of the spur.
    Now as for the flowering season, i wouldn't give too much about it, since mine also bloomed in autumn.
