Pteris umbrosa is a fern from eastern Australia. The habitat of the jungle brake is rainforest where it can form large colonies in shaded moist situations.[1] There are several populations of this fern in the northern suburbs of Sydney. However, it is not clear if they are indigenous or escapees from gardens.[2]
The botanist Robert Brown published this plant in the year 1810, in his Prodromus Florae Novae Hollandiae.
