Bulbophyllum medusae, commonly known as the Medusa orchid, is a species of epiphytic orchid with a creeping rhizome and a single leaf about 100 mm (3.9 in) long emerging from the top of each pseudobulb.

The flowers have thread-like lateral sepals about 120 mm (4.7 in) long, giving each cluster the appearance of Medusa.

[2] The Medusa orchid was first formally described in 1861 by John Lindley who gave it the name Cirrhopetalum medusae and published the description in Edwards's Botanical Register.

[3][4] In 1861, Heinrich Gustav Reichenbach changed the name to Bulbophyllum medusae.

[1] Bulbophyllum medusae grows on the trunk and main branches of trees in forest at altitudes up to 400 m (1,300 ft) in Thailand, Malaysia, Borneo, the Lesser Sunda Islands and Sumatra.
