Range of the genus Helicodiceros.

Helicodiceros muscivorus (Dead horse arum lily; syn. Helicodiceros crinitus,[1] Dracunculus crinitus [2]) is an ornamental plant native to Corsica, Sardinia, and the Balearic Islands. It is the only species in this genus. It reproduces the stench of 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.[3]
