    Default Bulbophyllum bolsteri

    I now here present for your perusal a Philippine endemic- Bulbophyllum bolsteri.

    The plant is from section Polymeres (formerly section Leptopus), a section characterized by creeping rhizomes and single-flowered inflorescences with short-lived flowers; during the bloom season however, it is not unusual to see opened flowers every day, and bloom seasons typically last for 2 to 3 months. In this species though, the 1.2 cm diameter flowers last only until, believe it or not, around 7 am.

    This species was named, by Oakes Ames in 1912, after F.H. Bolster, who collected the first plants of this species in Surigao on Mindanao during the period from May to June, 1906. No altitude data was ever recorded, although in Quezon on Luzon they are found between ca. 400 to 500 m asl.

    What a strange blooming habit! do they do this for some early morning pollinator or something? I know there is a species of Dendrobium that, doesnt bloom like this, but every flowering sized plant will bloom at almost exactly the same time, after monsoon, as their main pollinator is disturbed by the rainfall and comes out to feed on the nectar when the rains stop. I think....

    Thanks for the kind words, people. Jordan, I have often wondered what the pollinator could be, as the flowers obviously open very early at dusk, when insect activity is very low. This species regularly sets pods so I know that in my garden its pollinators, or at least alternate ones, are present. But so far I just couldn't get myself to wake up in those ungodly hours for me to solve the mystery of the pollinators' identity. And yes, there are several members of the Dendrobiinae which engages in synchronous flowering, which is usually triggered by sudden drops in temperatures, such as heavy rains preceded by a period of dryness. Why they do this is still anyone's guess though.

    You could always set up a continuous recording video camera linked to a nearby PC, then go over the footage. That would be better than waking up at 3 in the morning!

    thanks Wally for all the info!
    i've been watching it many times from opening 6am til 7.30am, and never spotted a possible pollinator around.
    fascinating species this!!!
