Full shade Warm Cool

Common Name The Flatly Braided Bulbophyllum [refers to the pseudobubls which are flattened and arranged in one plane]

Flower Size .16" [4 mm]

Found in Papua New Guinea without locality and elevational data as a mini-miniature sized, warm to cool growing epiphyte with a patent to pendulous rhizome with .44 to .64" [1.11.6 cm] between each obliquely recurved distant, oblong, deeply furrowed on the adaxial side pseudobulbs carrying a single, apical, dark green, elliptic, acute, usually distinctly convex, sessile base leaf that blooms on a porrect, .6" [1.5 cm] long peduncle, 2 bracted, 1.6 to 2" [4.5 to 5 cm] long, single flowered inflorescence with a tubular, acute floral bract.

"Bulbophyllum planiplexum differs from B. sawiense J. J. Sm. and B. intonsum J. J. Verm. in the new shoots growing from the very base of the pseudobulb, rather than from its sides. The adaxial side of the pseudobulb is distinctly concave, with flange-like edges firmly clasping the rhizome. The edges are not, however, fused around the rhizome. The pseudobulbs of B. planiplexum are also distinctly wider than in either species. The flowers are yeloow with a smnall patch of red at the apex opf the petals" J J Vermeulen 2008
