    I obtained this plant from Dale Borders, a former member on the forum. He had posted it labeled as Bulbophyllum labuanum. I am hoping I can get a confirmation or an identification.

    Hi Marni,
    I have seen this name before, but with no confirming sources. Hopefully some of the Bulbophyllum fans will comment.

    That is two thirds of the plant. The other part stayed in the greenhouse since it had grown through the 1/2 " hardware cloth it was growing on.

    Wow! Did you figure out the species? I don't know too many good Bulbophyllum books, and I was flipping through Bulbophyllum of Borneo by Vermulen et al. The closest was B. concinnum. IOSPE has a list of Section Desmosanthes in this link.

    Thanks, Naoki. I still haven't found the name. I should have pickled some flowers when I had the chance. I looked at B. concinnum, but the length of the inflorescence and the shape of the pseudobulb doesn't match.

    I too, believe it to be B.concinnum. since the flowers have now died, it may help with this brief description of the vegetative components of the plant.
    Rhizome slender, long creeping, rooting at all nodes, the nodes 4-5mm apart.
    Pseudobulbs curved upwards from a short prostrate base, cylindric, to 2 by0.4cm.
    Leaf about 4x1.3cm,narrowed abruptly to both base and apex, shortly stalked (exceptionally to 2cm wide).

    Hi Marni,

    I agree with the comments that your Bulbophyllum seems to me to be Bulb. concinnum.

    Jim Comber gives a plant description of narrowly ovoid pseudobulbs about 1.5 cm long by 5 mm in diameter, placed 4.5-6 cm apart, narrowly ovate to lanceolate leaves to 4 x 1.5 cm. Inflorescences much shorter than the leaves, the peduncle about 2 cm long with three small tubular sheaths spaced out on it, bearing five to seven flowers. Gunnar Seidenfaden mentions inflorescence of 2-6 flowers.

    References:
    Comber, J.B. (2001) Orchids of Sumatra. Natural History Publications, Kota Kinabalu, Borneo.
    Seidenfaden, G. (1979) "Orchid Genera in Thailand: VIII - Bulbophyllum Thou." Dansk Botanisk Arkiv. Udgivet Af Dansk Botanisk Forening, Copenhagen.

    Cheers.

    Gary

    There is one plant native to Hong Kong. Bulbophyllum stenobulbon. I have long been confused if it can stand. But just if you wish to check.
    Thanks

    I was wondering now that it's confirmed it as B concinnum, what conditions do you provide to get such an impressive specimen. I read it grows to 1280m above sea level, is it tolerant of cool temperatures or require consistent warmth. Thanks.

    I've grown it in intermediate conditions with 56F minimum nights and 80F maximum days.
