Discussion
Stereophyllum radiculosum is recognized by its dull, complanate-foliate plants with simple or sparingly branched stems; leaves with a single prominent costa that bulges on the abaxial surface; abruptly acute to obtuse leaf apices; and short, rhomboidal laminal cells, usually with a single papilla over the lumina on both surfaces of the leaves.
