`SECTION Brachyantha Rchb.f 1861

Synonyms SECTION Globiceps Schltr. 1913; SECTION Umbellatae Bentham 1883

TYPE species = Bulbophyllum umbellatum Lindley 1830

Characterized by the epiphytic nature with creeping rhizomes giving rise to pseudobulbs with a single persistent leaf that blooms on a usually 2 to many flowered, subumbellate, racemose inflorescence carrying resupinate flowers with the pedicel's basal node above the floral bract attachment. The dorsal sepal is free and it is usually 3 to 5 veined, the laterals are similar but they are usually 2 to 6 times as long and are usually twisted near the base so the upper margins turn inward and are free or adherent along their upper margins. The petals are 3 to 5 veined. The mobile, undivided lip is on a thin ligament and the column has the stigma proximally not protruding and the column foot is with or without lateral lobes near the apex. The stelida are approximately 1/2 the length of the column or shorter with or without a tooth along the upper and or lower margin. The anterior suface of the anther is concave and the anterior margin is drawn out into a rounded beak or not. There are 4 pollina.

There are more or less 26 species in this section occuring in montane forests at elevations up to 2200 meters from India to Japan, the Philippines and 1 species in New Guinea.
