Bulbophyllum sumatranum

Bulbophyllum sumatranum - Flower photo by Richard LindbergThe Bulbophyllum sumatranum is back in bloom. It has bloomed every year since I got it in 2009 at the SCOS member sale table. It has grown a little but I don't think I have divided it. Bulbophyllum sumatranum - Plant photo by Richard LindbergI will now because the sphagnum is quite broken down and has grown over the edge of the pot.

Bulbophyllum sumatranum grows in Sumatra needing low light and high humidity and blooms in the spring. The genus Bulbophyllum (Bulb) contains 1500 species found in all tropical areas on earth.

This plant is in sphagnum in a 5-inch clay pot. There are seven pseudobulbs and it stands eight inches above the pot. The youngest three pseudobulbs have leaves and that division will become the collection plant.


  1. KEW shows this to be a synonym of Bulbophyllum lobbii. I would assume then that cultural requirements would be nearly the same between the two.

  2. The synonym is for a variety, Bulbophyllum lobbii var brevifolum, named in 1908. The flowers are quite different and I think it is likely it was just a mistake that remains in the literature because it was published then.
