    Default Vanda (Euanthe) sanderiana var. alba

    I got this one only 6 months ago but it surprises me with a spike last month. I was hoping that the flowers would be fuller like the ones seen in certain orchid houses' catalogs or orchid websites. From the look, I think this one might be a diploid and the fuller/round flower form is a tetraploid.

    Cheers. Hoa.

    I do like the colour on this... and I didn't realise that ploidy played a part in vandaceous breeding as well... always thought it was very much a cymbidium and to some degree Paph breeding as well..

    cheers

    Hi Tim,

    Polyploidy plays important roles in the orchid world more often than you might think. Botanists believe orchids are the latest plants appearing on earth and they are still evolving. Polyploidy is one of the tools for orchid evolution.
    In addition to the alba version, I also bought the pink form. Both of them are in bloom at the same time!!! Again the petals/sepals are narrower than the ones I have seen at the show or exhibited by certain commercial growers. So I again think these plants are diploid.

    Hi Hoa,

    I will not enter the discussions "tetraploid" or "diplo´de" because I am not an expert.

    I just want to say that i enjoy very much your pink and alba form. I find your vandas splendid.

    I never had vanda!

    In complement of your photographs, I add a photo i took in an orchids show in France (I do not have any merit)

    Hi Phillippe and Orchid Forum Friends,

    Thanks for posting the gorgeous picture of V. sanderiana. That is beautiful. Now we can all see the differences between the two versions, the one that Phillippe took the picture from the show and the ones that I have. The one from the show is fuller and rounder. Tetraploid (4N), that is. I think these versions arise because these growers from the tropics have been line-breeding them like forever, sibling crosses and selfing and etc... I have seen triploid vandas too but that is rare.

    Cheers. Hoa.

    Your Vanda (Euanthe) sanderiana var. alba is gorgeous, Tony. Thanks for sharing. I love those colors together-so fresh, reminds me of Springtime.

    Hi! To all the Philippine Orchid lovers and growers!

    Vanda (Euanthe ) sanderiana had a lot of varieties
    namely:
    var albata rchb.f 1887- The flowers of this variety have a white dorsal sepal and petals with chartreuse spots near the column. The lateral sepals are tessellated or marke with chartreuse or apple green.

    var froebeliana Cogn.1903- The flowers of this variety are larger than the type species .densely covered with large mahogany brown reticulated veins.

    var labello-viridi Linden and Rodigas 1885
    The flowers are similar with the type species but that the lip is apple green color with reddish -brown stripes.

    var immaculata Golamco 2003
    The flowers are similar with the albata type but the sepals and petals including the shape of the flowers are different and much fuller than the albata type.

    Vanda sanderiana var. immaculata Golamco cannot be taken as a taxonomic variety. It is just a horticultural variety or cultivar. It is the resultant due to the series of selective line breeding done on V. sanderiana var. albata. This was initiated by the Hawaiian orchid breeders, to do away the traces of other color which stain the original var. albata, The effort finally purified the color to immaculate. I have written and called the attention of the Philippine Orchid Society and have submitted an article for their official magazine, discussing and elaborating the invalidity of the name V. sanderiana var. immaculata Golamco. Unfortunately, the current board of directors of the Phil. Orchid Society (2010) refuses to publish my treatise.

    Vanda sanderiana var. immaculata is an invalid name as a taxonomic variety. This is because the plant is a resultant of series of selective line breeding done on variety albata. As such it is just a horticultral variety or cultivar. As per ruling of International Code of Botanical Nomenclature (IUCN), any plant resultant to human intervention or breeding and is not found in nature cannot be given a taxonomic name, but just popular or commercial name, i.e. not Latinized name.
