    Default Dendrobium platycaulon

    A Philippine, New Guinea and Surrounding islands minature, hot growing, epiphytic species said to be a synonym of Dendrobium platygastrium found at elevations of 0 to 500 meters in dense humid forests near watercourses with very compressed, flattened pseudobulbs carrying a few, distichous elliptic-lanceolate leaves that blooms in the spring and again in the fall on a 1 1/2" [3.75 cm] long, erect, few [5] flowered, racemose inflorescence that arises from the nodes near the apex of leafed and leafless canes.(From IOSPE).
    I like the flat stems.

    Nice shot´s , however !

    Mine is growing under platygastrium and the lip is a little bit purplish
    isn´t it platygastrium or is the color from the blooms variable ?

    I am not 100% sute that the two species are the same. Actually, IOSPE"s Jay Pfahl proffered them separate.
    For example, the lip of your plant is pointed, and there is a purplish hue to the base. Also, do the ridges run to the edge of the labellum?

    His book, The Orchids of the Philippines, states that platycaulon is endemic to the Philippines.

    In the book Dendrobium and its Relatives, Bill Lavarck et all state that Dendrobium lamellatum occurs from Myanmar to Java, Borneo, and the Philippines. However, some experts prefer to use the term D. platycaulon for those plants found in the Philippines and D. lamellatum for those found outside of the Philippines.
    Drosera, I have the latter book in my lap, and I think your plant is Dendrobium platygastrium.

    hi nelson,

    that could well be and explains the confusion.
    ok then, we have "platycaulon", thanks for verifying that!

    Nelson, Andrea I think this one is Den treubii, initially i thought platysgastrium but this one totally different.
