2b. ssp. parlinii

A. plantaginifolia var. arnoglossa (Greene) Cronquist

Stems usually sparsely to moderately pubescent with purplish glandular hairs toward the tip. Basal leaves sparsely hairy or glabrous on the upper surface, often appearing cobwebby rather than woolly, even when young, becoming glabrous or nearly so at maturity. April–June.

Scattered nearly throughout the state (eastern U.S. west to Minnesota and Texas; Canada). Mesic to dry upland forests, upland prairies, savannas, and ledges and tops of bluffs, less commonly glades, ditches, banks of streams and rivers, and margins of ponds and lakes; also pastures, roadsides, and open, disturbed areas.

As interpreted here, this appears to be the more common phase of the species in Missouri. However, the two types do not seem to segregate by region or habitat in Missouri and do sometimes grow in proximity to one another.
