Rare Plant Species Profiles (G1-G3)
The rare plants featured in the following accounts are those species in Arkansas that have been assigned high global ranks. A high global rank generally implies that a species is rare and possibly threatened with extirpation or extinction (see Global Ranks for details). Although quite rare, these species lack federal status. Information on federally listed plants in Arkansas can be found by visiting Profiles of Federally Listed Plant Species. County level occurrence data for each species can be obtained through the Rare Element Search Engine.
