Cryptogamus Uranus is the scientific name given to a species of plant-like life forms from Uranus. They were discovered and named by biologist Patricia Hammond of the Gaea expedition of 2100.
They are zigzag-shaped, greenish-grey rope-like organisms, described as "loosely-organized", and reproduce by partition. According to Hammond, cryptogams (i.e. spore-producing species) are "probably the only sort of plant that can exist on Uranus, since there's no sign of bees, or other pollen carriers".
