Our species is Stenotaphrum secundatum (Walt.) Kuntze (S. 
americanum Schrank) (fig. 132), found near the coast from North 
Carolina to Florida and Texas, and southward, growing especially

vated as a lawn grass in the coastal

agated by setting out cuttings or 
pieces of the stolons bearing shoots.
