They are perennial herbs or subshrubs with yellow flower heads.Gray, Asa. 1849. Memoirs of the American Academy of Arts and Science, new series 4(1): 109Tropicos, Haploesthes A.

The name is sometimes spelled Haploësthes, with a diaeresis over the first e to indicate that the o and the e are to be pronounced in separate syllables. This is optional; either spelling is equally acceptable.International Code of Nomenclature for algae, fungi, and plants (Melbourne Code) section 60.6
