A. hirsutior is a perennial graminoid of the Poaceae family native to North America. [1]


A. hirsutior can be found on the southeastern coast, ranging from Texas and Oklahoma to New Jersey, with the exception of Delaware. [1]



A. hirsutior is a characteristic wetland species that often frequents the understory vegetation of Upper Panhandle Savannas. [4] It is also found mostly in longleaf pine forests [5] , as well as wet savannas, pine flatwoods, adjacent ditches, and other wet disturbed sites. [2]


A. hirsutior has been observed to flower between October and December. [5]

Fire ecology

A. hirsutior thrives when the following burning treatments are applied: periodic winter, periodic summer, annual winter, biennial summer. [6]

Herbivory and toxicology

A. hirsutior has been observed to host the Piglet Planthopper (Bruchomorpha oculata, family Caliscelidae).[7] A. hirsutior has fair forage value. [8]
