commonly known as remote thorny lignum, is a critically endangered shrub endemic to Western Australia.

It depends for its survival upon a regular cycle of freshwater flooding followed by drying of the lake bed.

This increase is attributable to a rising water table caused by widespread clearing for agriculture.

Other threats include interruption of the flooding/drying regime because of altered hydrology; and recreational activities such as water skiing.

[6] The whole lake bed ecosystem has been classified as a critically endangered threatened ecological community under the name Bryde.
