    DSCN3932.JPG DSCN3939.JPG We grow this specie in moist places with average light and where there is not a lot of vegetation as most don't get taller than around 15 cm. Possible the best feature of this specie are its leaves. It might not be easy to grow members of the Disperis genus in (very) artificial conditions and wonder if there are any other growers of this genus at Orchids Forum? NB: even the tag "Disperis" was not allowed....., or wrong name?

    Wow! Have never seen or even heard of this. Looks like it might be related to Brachycorythis?

    Accidentally we have Brachycorythis kalbreyeri also in flower, I would not say they are closely related, not in appearance and genetically (subtribes differ).

    Very interesting flower and foliage. Wasn't familiar with this species. My Brachycorythis kalbreyeri is ending its bloom for this year, just a few flowers left now. I posted photos a few weeks back.

    A genus I was not aware of. Looked it up and there a quite a few very nice species besides this on. Thanks for posting it.

    Indeed this genus is mostly from Africa. We have a number of species from this genus and all of them are flowering at this time (of the year). I will post at least another one shortly. I also checked on the relation between Disperis and and Brachycorythis, and indeed they are more related than I thought: https://en.wikipedia.org/wiki/Disperis. Never too old to learn.

    Does anyone know if this is in cultivation? Would be interesting to get a seed pod and try.

    Most Disperis spp. are not in cultivation as far as I know. Sourcing seeds is also extremely difficult. They can also be difficult to find in the wild because they are very small plants.

    Disperis and Brachycorythis are still somewhat distantly related. Disperis appears to be more closely related to the relatively better known Disa and even more closely related to the obscure genus Corycium. Whereas Brachycorythis are more closely related to Habenaria. All of the genera mentioned are related to each other in that they are part of the Orchidoideae Subfamily of orchids.

    The 5 subfamilies of orchids are:

    Apostasioideae
    Cypripedioideae
    (Slipper Orchids)
    Vanilloideae (Vanilla Orchids)
    Epidendroideae (e.g., Epidendrum, Cattleya, Encyclia, Phalaenopsis, Vanda, Oncidium)
    Orchidoideae (e.g., Habenaria, Platanthera, Brachycorythis, Disa, Corycium, Amitostigma, Disperis, Satyrium, Stenoglottis)

    Disperis is the correct spelling for the genus. They are relatively obscure orchids, so not many people have heard of them.

    Thanks for explaining the relative relations between the genera!

    Indeed Disperis spp. are difficult to find when in hibernation. Though I cannot talk about experiences by others, I find them not difficult to spot when they are above ground and actually easy to spot while flowering, because often the background is green only and also other vegetation short(er). Moreover, the different species, or at least the majority of the Kenyan ones, grow in specific undisturbed habitats, with some overlap. And when e.g. Disperis dicerochila is flowering on a tree trunk it is simply standing out. See my next post.

    A welcome surprise, some seedlings:

    Disperis seeds, like more terrestrials, are not that tiny, and maybe not so much wind when the seeds were released and therefore stayed close to home. Do not seem to flower in y1.
