A rare chance to see a rare plant in flower!

Occupying small pockets of private land and an area of National Park included in the Greater Blue Mountains World Heritage Area, this species is threatened by habitat disturbance and degradation. It could also be threatened by inappropriate fire regimes and the introduction of fungal pathogens to its habitat. It is listed as Vulnerable under both the New South Wales Threatened Species Act 1995 (TSC Act 1995) and the Commonwealth Governmentís Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act 1999).

One of a small, closely related group of species that also includes G. capitellata and G. diffusa, that occurs in fairly small areas around the rim of the Sydney basin, all characterised by small, reddish and tightly globose flower heads, often dangling below the foliage and in some species often on the ground surface. Despite their small size, the flowers can be nectar rich, and are visited by a variety of honeyeater birds.
