[1] The close branching of shoots, short internodes and tightly packed stems cause the characteristic hemispherical shape of a cushion plant species.

[2][3] It can spread approximately 1 metre in diameter with its adventitious roots forming at various points along the prostrate branches.

It exists in montane vegetation and bolster heath communities throughout the alpine areas of the central and western Tasmanian mountains.

Convergent evolution is defined as when different lineages of structures are similar to each other, but do not share a common ancestor.

[3] Additionally, the density of the packed stems in the cushion plant prevents deep freezing during the winter months.
