    Default Dendrobium nudum

    petal nudumDendrobium nudum – some now move this to Anisopetala when presumably it becomes A.nuda.

    Rather few flowered – always, as far as I can see. My plant manages 2 or 3 flowers per spray, from one or two nodes on each of four leafless canes , but they do go on flowering for several years – at least five in the case of one of my canes. I also have about three canes on their way to being leafless, i.e. down to just one or two leaves, which may join in, next time around, and three or four new growths coming up towards full length ( 2 feet). The canes are thin, maybe only 4 or 5 mm, say 1/8th inch.
    I have not been able to find any illustration or reference suggesting better , in fact I can see more flowers on my plant than on any of the pics I have found, but of course growers often show just a single flower so as to be better seen; so I don’t know.
    I have discovered that it likes shade, and I have been growing it brighter, so I’ll change my culture now.
    Flowers btw an inch to 1 ˝ inch in size, and clearly very variable in colour, from dark yellow through white to pale green, almost always with the pink veining seen here.

    Be interesting to see if the plant "protests" your changing its conditions.

    This is a very interesting one. Thanks for showing it.

    The info I have on this one recommends 1500 - 2300 fc. Also it mentions 2 - 4 flowers per inflorescence if that helps.

    You are quoting Baker & Baker ? I am afraid that I take everything they say with a pinch of salt - could explain, but won't delay to do so here.
    But their entry for D.nudum is typical ; it does indeed say 1500-2300fc- which is bright enough to flower Cattleyas, broad-leaf Vandas, and is also what is recommended for Neofinetia , and this is probably more than my average light ( and I flower all of those, easily and frequently) . BUT they also say "they always grow in the shade" and " indicating that light is relatively low".

    Sorry, Baker, and Baker - 2000 ( to take a mid point) fc is simply not relatively low. I have taken readings on the leaves of Vandaceous plants growing in dappled sunlight and had such figures !

    In short, it does not add up.
