|Bulbophyllum (Cirrhopetalum) medusae|
Not that it doesn't smell a bit funky--it does, as one might reasonably expect from a fly-pollinated Bulbophyllum. But the fragrance is pretty mild compared with the body-buried-under-the-stairs stench of Bulbophyllum carunculatum, or the road kill-with-bleu cheese bouquet of Bulbophyllum falcatum.
No, Bulbophyllum medusae dances rather than twitches in the breeze, an invitation to pollinators to come hither. The flower spike is a many-flowered umbel, like a globe-shaped Queen Anne's Lace. Each creamy flower has long (up to 8 inches) graceful sepals. Any twitching that occurs goes on inside the flower, each of which has a hinged petal (lip) to throw the pollinator off balance and up against the pollen masses.
It seems entirely fitting that Bulbophyllum medusae flowers at Halloween. A terrific addition to our Medusa orchid collection.
