LATE EARLY

Common Name The Winged Stelida Bulbophyllum

Flower Size .2" [5 mm] wide

Found in Papua New Guinea in forests at elevations of 1600 to 1700 meters as a mini-miniature to miniature sized, cool growing epiphyte with .16" to .88" [.4 to 2.2 cm] between each distinct, loosely clustered to shortly creeping, obliquely erect, ovoid pseudobulb with age wrinkling along numerous longitudinal lines and carrying a single, apical, erect, elliptic to elliptic-obovate, acute, petiolate base leaf that blooms in the late winter and early spring on 1 to a fascile of a few, basal, peduncle .32" [.8 cm] long, provided with 2 scales, 1.2" [3 cm] long overall, single flowered inflorescence with much shorter than the the ovary floral bracts.

Most similar to B phaeoglossum which does not have ciliolate lip margins and B gunteri but B pterodon differs from both in having the petals more than half as long as the median sepal and by the presence of a distinct, obtuse wing along the upper margin of the stelida.
