Origin

Notes

Hairy woodrose (Merremia aegyptia) is regarded as an environmental weed in the Northern Territory and northern Western Australia. It is also listed as a priority environmental weed in at least one Natural Resource Management region in northern Australia. This fast growing twining vine has escaped from gardens and covers native plants, trees and fence lines in disturbed sites and riparian areas.

Hairy woodrose (Merremia aegyptia) has taken over large areas of disturbed land in northern Western Australia, particularly around Broome and Kununurra. It has also been reported from vine-forest margins near Darwin in the Northern Territory and recorded from conservation areas in this region (e.g. Holmes Jungle Nature Park). This species is also listed as a medium priority weed in aboriginal lands in the Northern Land Council area.
