Haplophyton is a genus of plants in the family Apocynaceae, first described in 1844. It is native to the southwestern United States, Mexico, Cuba, and Guatemala.[1][2] It is a suffrutescent herb with alternative leaves and showy colorful flowers.[3]
The common name cockroach plant (or hierba de la cucaracha) is in reference to its insecticidal properties. It has been used to kill cockroaches, fleas, flies, lice, and mosquitoes.[4] Leaf extracts and sap contain many insecticidal compounds — such as the indole alkaloid aspidophytine.
Species[edit]
Some authors accept three species in the genus, others recognize two, considering H. cinereum synonymous with H. cimicidum. The World Checklist recognizes:
- Haplophyton cimicidum A.DC. (syn H. cinereum (A.Rich.) Woodson) - Michoacán, Puebla, Morelos, Oaxaca, Chiapas, Guatemala; naturalized in Cuba
- Haplophyton crooksii (L.D.Benson) L.D.Benson - S Arizona, SW New Mexico, W Texas, Sonora, Chihuahua, Coahuila, Cuba
