Distinguishing Features
Infrequent and easy to confuse with other two-lobed species, Geocalyx graveolens creeps loosely over its substrate, its yellow-green shoots bearing leaves that spread out widely (to 3 mm) from their longways attachment to the stem. The lateral leaves are shallowly-lobed (less than 1/4 the leaf’s length), their tips sharp but triangular, while the underleaves are clearly visible with a hand lens and are also clearly two-lobed. When sporophytes are present, they emerge anomalously along the underside of the shoot.
