Bulbophyllum medusae

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 long emerging from the top of each pseudobulb. The flowers are creamy yellow and arranged in clusters of about fifteen arranged in a circle at the tip of the flowering stem. The flowers have an unpleasant odour. The flowers have thread-like lateral sepals about 120 mm long, giving each cluster the appearance of Medusa.

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. In 1861, Heinrich Gustav Reichenbach changed the name to Bulbophyllum medusae.

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