Note
|
The species was the first member of the genus to be collected and described. The species seems to occur in two slightly different forms. The typical form is most common at lower elevations and has a more acute leaf base and scarcely lacinate inner involucral bracts. Specimens from Guatemala, Mt. Ovando in Chiapas, and from Panama have more abrupt leaf bases and laciniate inner involucral bracts.
