Range of the genus Helicodiceros.

Helicodiceros muscivorus (Dead horse arum lily)[3][4] is an ornamental plant native to Corsica, Sardinia, and the Balearic Islands. It is the only species in this genus.[2][5][6]

The flowers of Helicodiceros muscivorus smell like rotting meat, attracting carrion-seeking blowflies which act as pollinators. One of a rare group of thermogenic plants, the Dead Horse Arum can raise its temperature by thermogenesis. This helps to lure flies into the plant to contact its pollen.[7]
