|discussion=<p>Dichanthelium portoricense subsp. patulum is more common in moist, sandy pinelands and savannahs than subsp. portoricense. It also grows in coastal sand dunes, but is less abundant there than subsp. portoricense. It is the more variable of the two subspecies, grading into subsp. portoricense as well as D. commutatum. More robust plants are recognized by some as Panicum patentifolium Nash. Occasional specimens, recognized by some as P. webberianum Nash, resemble the widespread D. sphaerocarpon.</p>
