    Default Phalaenopsis pallens

    Phalaenopsis pallens is endemic to the islands of Luzon and Mindanao, in the Philippines. It has not been utilized much for hybridization because of the pale color; they all want the more intense yellow colors from Phalaenopsis fasciata.

    Default Thank you for sharing your picture of a virused phal.

    I think I have seen that before, and I will be on the lookout for that.

    In my case, we were several people to buy pallens at the same nursery.
    They all came from the same mother plant (keikis).
    An orchid and virus expert said that it was infected by BYMV.
    One among us did a positive Elisa test to confirm
    It was just for the history

    Yikes! I have a few Phals with that pattern on new leaves. I thought it was just the way some are...
    Lovely species of Phal. Thank you for sharing those beautiful blooms.

    It’s very difficult to make a diagnostic only with photographs.
    Virus diagnostic should be confirmed by elisa test.

    The pallens had spots on the young leaves and disappeared after.

    On the other hand, it exists spots on the young leaves which disappear then.
    They can be dependent on the pigmentation and in this case it’s normal.

    Very nice picture of the Phal. pallens!

    BTW, Philippe, what is the full name of the BYMV? I could tell that is some kind of mosaic virus (?) but what the BY stands for? Symptoms and manifestations of the infection, could you tell us more? Thanks. I am concerned since I also have a very nice phal species plant, and i hope it does not have this virus! Where could we get a kit to test for this virus? Thanks (ou Merci beaucoup!).

    Cheers. Hoa.

    I Hoa,

    BYMV = Bean Yellow Mosaic Virus

    I'm not a virus specialist. An expert of this kind of things, on another forum helped us.

    here an other photograph.
    Elisa tests is rather complicated to make for an amateur.
    It is a laboratory work!

    Ah, tres bien, Philippe! Merci!

    Actually I have access to laboratory and I could do the test myself if I want to. (Elisa is an immuno assay and it is based on a technique that we call Western Blot). But thanks a bundle for the name and the other picture of the leave. That is VERY INFORMATIVE.

    Regards.
    Hoa.
