    A first flowering seedling from a very successful outcrossing. One has been awarded so far. Still many to go around the country.

    Gosh, that is quite a denisoniana! Super-round, full, concolor and no spots.

    That is a gorgeous -- and as was said before it is perfectly round! Usually there is some twisting or marking of the sepals or petals. Well done -- a nice outcross indeed.

    Sorry to disappoint but this is an Ascocenda. The petal shape is wrong, the column is too short, and the lip is held at the wrong angle. A lovely thing but not the species. Odds are this has no fragrance while denisoniana has a cloying Magnolia-like fragrance at dusk.

    Well, sorry to disappoint you, this has one of the most delightful scents I've smelt in a Vanda and this plant has been line bred over many years. Other plants from the cross have been awarded and I know of atleast 2 that are now being used for breeding in Thailand. The original plants used years ago were very select wild collected plants. I have known the breeder for decades.

    It is still an Ascocenda and not Vanda denisoniana. I am aware of awards in South Africa (on the cover of Orchids South Africa 2009 #2) and the U.S. and these are all in the process of being overturned. I wasn't attacking anyone but somewhere along the line a hybrid was added to the mix. What time of the day is your plant fragrant?

    The fragance is there from around 3pm till late. When it was fresh out there was nothing, on flower maturity, maybe a week, the fragrance came thru. Not sure where the hybrid would come in as the breeder does all his own work including flasking. Rarely, if ever does he use hybrids, too careful & knowledgable for that.

    Hybrids keep creeping into blood lines, in large part because of award systems which too often reward the "improved" species. In the U.S. there are clear hybrids awarded as coerulea, merrillii, and tessellata. When it gets to Phalaenoosis its gets really bad and "select" species are often quite complex hybrids. My bet would a common scenario of "I've got a really good clone in flower. I'll give you pollen and we can split the flasks." Martin Motes of Motes Orchids in Homestead, Florida, has a great expression - bad hybrids replace good species. The hybrids may be close to the species but will have slightly better shape, a few more flowers, etc.
