Common Name or Meaning The Wingless Bulbophyllum

Flower Size .4" [1 cm]

Found in southern Venezuela, Guyana and northern Brazil at elevations of 800 to 1600 meters as a miniature to small sized, hot to warm growing epiphyte with close set, ovoid, tetragon, each face concave sided pseudobulbs and carries a single apical, erect, coriaceous narrowly ovate, obtuse, constricted below into the short petiolate base leaf that blooms on a basal, erect, to 18" [45 cm] long, several to many flowered, racemose inflorescence with elongate bracts that partly envelop the flower.

There are 4 species with single leaves reported from Colombia having petals with short, ciliate, pilose or ciliolate margins, B exaltatum, B sanderianum, B popayanense and B meridense In B popayanense and P meridana the petals are 3 times shorter than the sepals. B exaltatum and B sanderianum have petals half as long as the sepals and are separated by the lip shape.

Many references include B warmingianum as a synonym but I have left them separate pending more research.

Please proceed to B geraense as well as it is a very similar orchid flower. You will see the stated differences there.
