Discussion

Dichanthelium acuminatum subsp. longiligulatum is common, especially in moist pine savannahs and bogs of the coastal plain; it also grows inland to Tennessee, and in Mexico, the West Indies, Central America, and South America. It is similar to subsp. leucothrix, which grows in the same habitat, often at the same sites.
