SECTION Sestochilos [Breda] Benth & Hook.f. 1883

Type: = Sestochilos uniflorum Breda = Bulbophyllum lobbii Lindley 1847

Synonyms SECTION Stenochilus J.J. Sm. 1914

Characterized with distinct pseudobulbs giving rise to a single flowered inflorescence with amplexicaule floral bracts that may be tubular at the base only with free, equally long, obtuse to acuminate, margins entire, glabrous, 5 to 14 veined sepals and obtuse to acuminate, margins entire, glabrous, 5 to 12 veined petals with a mobile lip on a thin ligament, usually undivided, elliptic or oblong to obovate to triangular, or with a wide, triangular, hastate to cordate basal part and a narrow drawn out apical part, adaxially more or less concave near the base, sometimes with 2 converging ridges, adaxial surface glabrous, sometimes partly hirsute, abaxial surface glabrous, and has a stigma with 3 inner keels and a tapering towards the apex or not, and without teeth and carries 4 pollina.

SECTION Sestochilos differs from SECTION Beccariana in the base of the pedicel which is more than 1 times its diameter distant from the floral bract attachment.

There are 45 or so species in this section occuring in forests at elevations up to 2800 meters in India, Nepal, Bhutan, Myanmar, China, Taiwan, Japan, Thailand, penninsular Malaysia, Vietnam, Laos, Sumatra, Java, Borneo, the philippines and eastward to the Solomon Islands.

Entries below with an asterix are listed in publications by J J Vermeullen and so are more likely correct than ones without. Species with a question mark in front, seem to me to not conform so please use with caution.

There are way too many species represented here so many of these are actually within the section Beccarina, they will be sorted out soon
