Distinguishing Features
Restricted to high latitudes and altitudes, the erect yellow shoots of Odontoschisma macounii stand to about 1 cm tall with leaves that spread out from the stem near to a 90 degree angle. The lateral leaves are unlobed, but it is the similarity in shape and size of the underleaves (see photo) that makes this species distinct in the genus.
