The 42 known species of the parasitic plant Rafflesia, known as the corpse flower, are endangered due to destruction of forest habitats

Parasitic, elusive and emitting an overwhelming odour of putrefying flesh, Rafflesia – often called the corpse flower – has intrigued botanists for centuries. Now, scientists are warning that it is at risk of extinction and calling for action to save it.

The blooms of the Rafflesia have become famous for their odour of decaying meat, produced to attract flesh-eating flies. But the genus – which includes the largest flowers in the world, at more than a metre across – is at risk due to the destruction of forest habitats in south-east Asia. There are 42 species of Rafflesia, and researchers warn that all of them are under threat, with 25 classified as critically endangered and 15 as endangered.
