A frequent plant of sandhills, scrub and pine flatwoods occurring only the the Florida peninsula north of Lake Okeechobee.
The ray florets are lacking on the distinctive flowers of this genus. The most prominent feature of the Florida indian plantain flowers are the five green winged phyllaries of the cylindrical disk florets. Leaves are alternate, strongly veined and oval or broadest near their base. The lowest leaves are crenate and 7 to 9 nerved. Plants can reach over a meter tall with a grooved, glabrous stem branching in the upper part of the plant.
Of the two endemic Arnoglossum, A. floridanum is more widespread than A. album, which is only found in Bay and Gulf Counties.
