Serrulatocereus
Serrulatocereus is a genus of cactus endemic to northwestern and central Haiti. It contains a single species, Serrulatocereus serruliflorus. 

It was originally named Cereus haitiensis, but that name is illegitimate as it had already been used for another species. The specific epithet ayisyen means "Haitian" in Haitian Creole.
