WEAKLEY FLORA

SCIENTIFIC NAME: Tripsacum dactyloides var. dactyloides
COMMON NAME: Gama Grass
SYNONYMY: [= FNA, Va, Z; < T. dactyloides - C, G, K, Pa, RAB, S, W, WH3, WV; > T. dactyloides var. dactyloides - F, HC; > T. dactyloides var. occidentale Cutler & Anderson - F, HC]
PHENOLOGY: Late May-Nov.
HABITAT: Roadsides, moist areas, disturbed areas, moist riverbanks.
COMMENTS: T. dactyloides is widespread in e. North America north to MA, MI, IA, and NE, ranging south into tropical Central and South America; var. dactyloides is North American. This important species of moist and wetland areas in the Great Plains is generally seen in disturbed habitats in our area; its original habitats in various parts of our area are poorly understood, and it may not be truly native throughout the Southeast.
