    This is currently in Dendrobium and Dockrillia rigida is a synonym.

    This species has been posted many times here but this one has a different lip pattern that I thought was interesting. This is the first flowering in my care and there are other spikes just emerging.

    It looks like the newest growths are really starting to spread out. Am I right in that assumption or is it just the orientation of the photo?

    It is fanning out. There is another new growth on the other side of the plant that is growing horizontal. The new growth facing the camera is the only one I have noticed, on this plant, that is actually branching off another pseudobulb vs. originating from the central point.

    Last week I acquired another clone and it is a creeper. I look forward to it blooming because I'm not convinced it is a rigidum but perhaps nugentii or some other species I am not familiar with. If I remember to do it I'll photograph it and post it here for comparison.

    I agree. They are among my favorites.

    Here is the new acquisition that is supposed to be D. rigidum but looks different than any I have seen. Do any of you Aussies have an opinion?
    I'll probably have to wait for some flowers to tell for sure.

    Healthy plant and nice looking flowers! I need to check if mine is in spike as well. :)

    Perhaps it is a cross hybrid. Either way I like it...the dark leaves make it stand out.

    Here are the same 2 plants one year later and both in bloom.

    Dendrobium rigidum 2 plants-900.jpg

    This is the one from my original post last year ...
    Dendrobium rigidum Andys-900.jpg

    This is the second plant that I was wondering about the species. It certainly looks like a D. rigidum but the habit is so different. However, the flowers are so similar to the one above that they could be siblings ...

    Hi Kelly,

    Dockrillia rigida [Dendrobium rigidum] is so variable in plant habit, leaf form and leaf colour as well as being highly variable in flower colour. The markings and colouration of the lip can also be very different between the various cultivars.

    It's rare to get two that are so similar in colour pattern, especially from different sources.

    I illustrate flowers of 4 different Doc. rigida under Digital Images on my website: www.yonggee.name

    Cheers.

    Gary

    Thank you, Gary. I appreciate the response.

    Besides the obvious difference in plant habit, the primary difference in the flowers is not portrayed in my photos. On the cork mounted plant the mentum has more pink as well as more pink on the tips of the tepals. I think I will cross these two.

    That is certainly better (more) flower color than on what I've grown.
