    EDIT: 3/9/2014 I now believe this to be Dendrobium calamiforme and I have changed the thread title accordingly.

    After reviewing Marni's post from 2009 ( http://www.orchidsforum.com/threads/dockrillia-teretifolia.909/ ) I should be embarrassed to post my plant, but here it is anyway.
    Grown bright, mounted, intermediate. I reduce the water in the winter but don't give it a dry rest. This plant struggled for a few years until I found its niche but is doing fine now. There appear to be at least 3 more spikes starting. Dockrillia teretifolia front-1000.jpg Dockrillia teretifolia profile-1000.jpg Dockrillia teretifolia plant-1000.jpg

    Kelly, I think this is Dendrobium fairfaxii and not D teretifolium. The pseudobulbs of this species are thicker and the growth pattern is different. It is a very nice plant.

    Interesting. I was given a small piece of this and was told that it was Dendrobium teretifolium but we all know how unreliable that can be. So, I've been doing a little reading.
    I just measured the leaves and counted the blooms on mine. The longest leaf is 44 cm and approx. 5-6 mm in diameter. There are 11 blooms on the inflorescence. The leaf size could fit either D. teretifolium or fairfaxii. However, D. fairfaxii only has 1-4 blooms on the inflorescence. Another possibility would be Dockrillia calamiformis (previously called Dendrobium teretifolium var. fasciculatum). Of course there is always the possibility that it is a hybrid and the person that gave it to me didn't know what it was. I'll keep researching it.

    I have some plants of "D. teretifolium" that I got about 5 years ago as seedlings. I haven't bloomed any of them yet, but the growth habit is not like my plant.

    Here is a link to Dendrobium/Dockrillia from Ron Parsons Picassa images. Ron has made many trips to Australiain the last 10+ years and frequently spends 4 to 6 weeks there at a time, all orchid related. The Dockrillia calamiformis - Orchid Species Plus is from a species grower/vendor in Austrailia. The Dockrillia fairfaxii - S Stebbing is also an Australian grower.

    Thanks, Marni. So do you think that your seedlings are not D. teretifolium?
    Here is a link to a web site that I came across with photos from Australian growers. https://plus.google.com/photos/107706963036332579805/albums/5826025599572045873?banner=pwa There seems to be a lot of variation in the teretifolium, both flowers and growth habit. Just from a cursory review of the photos it seems that mine most closely matches the Dockrillia calamiformis. I'm fairly certain that it is not the D. fairfaxii mainly due to the flower count.

    And the flower shape. I also think it looks a lot like calamiformis

    I doubt they are, but until they bloom I don't know. I do have to remind myself that the flower is the determining factor in ID. You have a fabulous thing there and I can only hope that mine turn out to be the same.

    I just bloomed the first of the seedlings I was talking about. Silly me, I didn't get a photograph, but they look much more like Kelly's plant than my D teretifolium.

    I changed the title of the thread to Dendrobium calamiforme. Here is a link to an Australian forum showing a plant and blooms that appear to be the same as mine. http://www.orchidsonline.com.au/node/7676

    Mine turned out to be Dendrobium fairfaxii. Not as elegant as yours, Kelly.

    Based on measurements it appears to be Dendrobium calamiforme. The inflorescence had 9-10 flowers and the inflorescence photo is just the lower portion that still had some past-prime flowers that were about to drop.
