Discussion

Epipterygium tozeri is a characteristic species of soil banks in redwood forests of the Pacific coast. The soft pale bluish color is distinctive when plants are growing in well-developed turfs. Epipterygium tozeri can be distinguished from any Pohlia by the (sometimes subtle) complanate foliation with smaller dorsal than lateral and ventral leaves, broad, nearly elliptic leaves, weak costa ending about 2/3 up the leaf, and by marginal laminal cells differentiated from the medial as longer, narrower, and more thick-walled.
