Common Name The Straight Petaled Bulbophyllum

Flower Size 1" [2.5 cm]

Found in Papua New Guinea on cliffs in full sun, without locality as a large sized, warm to cool, pendent growing epiphyte or lithophyte on cliffs with out plant details but said to be similar to B phalaenopsis that blooms on a basal, to 4" [10 cm] long, to 3 flowered inflorescence with bracts on the peduncle and a circular, apically acuminate floral bract and carrying simultaneously, barely opening flowers that smell of rotting meat.

CAUTION!!! Vermeulen states that the flowers are cream-coloured, but heavily mottled with purple which the provided photos are not so please use with caution!

" Bulbophyllum fletcherianum Hort. and B phalaenopsis differ in having lateral sepals which are hairy abaxially. Bulbophyllum macrobulbon Schltr. has distinctly recurved lateral sepals. Bulbophyllum cruentum Garay, Hamer & Sigerist has two distinct, short, papillose swellings halfway down the lip, and is much smaller vegetatively." J.J. Vermeulen 1993
