Phenotypic plasticity of the stem epidermis in the bluegrasses (Poa L.) of section Stenopoa Dumort. (Poaceae). I. Mesomorphic species
SectionStenopoaDumort. is one of the largest representatives of the bluegrass genus (PoaL.). Despite relative antiquity,P. palustrisL. andP. nemoralisL. have not been perserved in original states. Their ongoing evolution and hybridization has increased their diversity and has complicated the system....

SectionStenopoaDumort. is one of the largest representatives of the bluegrass genus (PoaL.). Despite relative antiquity,P. palustrisL. andP. nemoralisL. have not been perserved in original states.
