    Bulbophyllum bicolor. Section.Cirrhopetalum. Dist: Indo-China, N.W. Yunnan and Hong Kong. 2.bicolor.JPG
    The inflorescence which reaches 2" to 3" long, produces 2 to 8 flowers. Each flower is 1" across and 2" long. The sepals are creamy white, and longitudinally veined red-purple. The lip is yellow or yellow green heavily spotted red at the base.. Likes to be kept moist, that is why I keep it mounted, then it can’t be overwatered. Bright light and intermediate temperatures suit this species.

    The original Bulbophyllum bicolor which is found in wild in Hong Kong is a much smaller plant with smaller flowers. This plant some how originated from Thailand and so far no one I know, have given me a proof of its occurrence in wild in Thailand although few claimed to have seen it. Please find the image of one from HK attached here.

    I hope that the following will throw some light on your query.

    Bulbophyllum bicolor Lindl., Gen. Sp. Orchid. Pl.: 49 (1830).
    This name is accepted by: The World Checklist of Selected Plant Families.
    Distribution: China (NW. Yunnan, Hong Kong) to N. Indo-China
    CHC CHS 41 LAO THA VIE.

    Work is underway at Kadoorie Farm and Botanic Garden in Hong Kong to clarify relationships and identify common factors involved in the decline and extinction of species in the wild. All native Hong Kong species will be barcoded, and spatial genetic structure will be investigated in the near-endemic B. bicolor to elucidate ecological processes at the population level. During the course of survey work throughout South China and neighbouring countries in the Indo-Burma region, material will be collected for morphological and genetic studies that aim to provide better resolution of species numbers and distribution also abundance and conservation status of species across the region.
    Your answer may be found in the results.
    I see the image you show is in the article where I recovered the information above.

    I actually was in Hong Kong in this farm... which doesn't look like has or had ever any research center...
    any way I saw there like plenty different forms of it, from smaller to much bigger...
    and actually this bigger which look like on steroids are really attractive. Pretty sure it is just polyploid genetic form of it... IMG_8460.jpg IMG_8514.jpg IMG_8515.jpg of it.

    I agree with Piotr, with regards to the 'Kadoori Farm and Botanic Garden'. What is interesting, he says he saw plenty of different forms of Bulbophyllum bicolor. So it's possible that 'The Hong Kong Zoological and Botanical Gardens' which is one of the oldest zoological and botanical centres in the world and opened 1871, agreed to work and research on the many forms and different sizes of B.bicolor at 'Kadoori Farm'.

    I work at Kadoorie Farm and we do scientific research, but our policy doesnt include advertising our work as most of other botanic gardens in the world do. Infact being here for over 5 years, I have not heard HK botanical and Zoological garden doing any such research other than being a PARK. Yes we have atleast three distinct forms (yellow colour, yellow with stripes and a large sized form. rest of the variants are not really distinct from each other) at the farm. The large forms were exported from Thailand and we have the native ones from HK. I dont know who is behind the name Seidenfaden but is that you Brett with the name Piotr? I thought you already know that we have research labs here conducting ecological and genetic research on orchids and other groups especially in Indo-Burma.

    My point was not about the what form the bigger one is. My point was, many of my friends say that they have seen the bigger form in wild in Thailand, but so far no one could give me a proof of it. I would be grateful if some member can provide some info. Originally the one described was a smaller form according to the protologue.

    Thanks for the information Pankaj, I now have a better understanding of your query.
    I do have contacts who live in Thailand and I shall ask them for any info that they may have on B.bicolor. I wish you success in your project.
