Discussion

Variety viridis is widespread and sympatric with the other varieties except var. glabriuscula, with which it shares a diffuse boundary. Reports from Kansas, Oklahoma, and Texas need confirmation. Variety viridis grades into var. glabriuscula, var. lanceolata, var. ovata, and Crataegus nitida.
