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.
