Part shade Cold Spring

Common Name The Moustache Bubophyllum [referring to shape of the hairy patches on the lip]

Flower Size .12" [3 mm] wide

Found in Papua New Guinea in Casuarina forest at elevations around 2500 meters as a mini-miniature sized, cold growing epiphyte with a creeping, the new shoot arises from the basal node of the pseudobulb rhizome with thin, little persistent rhizome scales with .12 to .2" [.3 to .5 cm] between each distinct, ellipsoid, hardly angular but concave on the side where the new shoot arises pseudobulb carrying a single, apical, erect, elliptic to obovate, subacute petiolate base leaf that blooms in spring on a single or several together, ca. 3.2" [8 cm] long, peduncle ca. 1.8" [4.5 cm] long, provided with 4 scales about single flowered inflorescence with shorter than the ovary floral bracts and carrying dark red purple flowers.

"Shares the clustered growth, combined with narrow sepals and short, upwards falcate stelidia with Bulbophyllum galliaheneum Van Royen, from which it differs by the elliptic to ovate, acute (versus obovateoblong, subtruncate to rounded) petals, by the much denser and larger hirsute patches proximally on the adaxial side of the lip, and by the triangular (versus narrowly triangular and distally subulate) stelidia; and with B. odontopetalum Schltr., from which it differs by the elliptic to ovate, minutely erose and/or ciliolate (versus obovate-spathulate, coarsely fimbriate) petals, and by the hirsute (versus glandular-papillose) lip margins."
