Common Name The Feathery Bulbophyllum

Flower Size 3 3/4" vertically [9cm]

Found in Malaysia, Sumatra and the Philippines in swamp forests at elevations around 1000 to 1500 meters as a mini-miniature sized, cool growing epiphyte with .8 to 1.2" [2 to 3 cm] between each, obliquely ovoid, quadrangular with concave sides pseudobulbs and carrying a single, apical, lanceolate, narrowing into the very short petiolate base leaf that blooms on an ascending, slender, terete, 4" [10 cm] long, apically thicker, 4 flowered, umbelliform inflorescence that is held at the leaf height.

This species should be grown in a pot or basket with fast draining medium and partial shade.

There is an all white version of this flower which was in the original description and has been known as B jacobsonii and there is a var flava which is all yellow.

Very similar to B treschii but it differs in the wrinkled, rugose sepals and the lip that appears shorter, more darkly and heavily spotted and more squared off and obtuse at the apex.

Synonyms Bulbophyllum jacobsonii J.J. Sm. 1935; Rhytionanthos plumatus [Ames] Garay, Hamer & Siegrist 1994
