Distinguishing Features
A rare species of high altitudes and elevations, G. revolutum is variably red along its relatively wide (1-2 mm) and long (up to 5 mm) prostrate shoots of loosely overlapping leaves. The leaves are made up of two equal and rounded lobes, but along their sides that are "revolute"– they curl downwards (see photo). There are no oil bodies in the fresh leaves when inspected under the microscope.
