Scientific name: Grevillea masonii
Profile last updated:
21 Mar 2022
Description
Mason's Grevillea is a low-growing shrub to 1.5 m tall, with many short, erect branches. The leaves are rounded at the tips and have a tiny projecting point. The lower surface of the leaves have sparse, silky hairs and the new growth is green. The flowers are red and green, hairy inside and out, and occur in groups of six to ten. The dry fruit has a long, upward-curving projection like a swan's neck.
Distribution
Occurs in only a few locations between Grafton and Casino in north-eastern NSW.
Habitat and ecology
- Occurs on gravely loam soils and in sand in open eucalypt woodland.
- Resprouts from its lignotuber following disturbance; also regenerates from seed after fire.
- Flowering usually commences from two to three years of age.
- Sets plentiful seed and the seed morphology suggests that wind, gravity and ant dispersal; seeds germinate after fire.

Threats
- Agricultural clearing has probably been the main cause of decline of this species.
- Continued physical disturbance from frequent roadside slashing.
- Risk of local extinction because populations are small.
- Too-frequent or too-hot fires can lead to adult plants not being replaced from soil-stored seed reserves.
- Invasion of habitat by weeds, particularly introduced grasses.
- Potential for maintenance of powerline easements (spraying and slashing vegetation) to have degrading effects on the species if significantly changed.
- Current or potential future land management practices do not support conservation.
- Very little knowledge of the location of individual plants / populations within the site.

Activities to assist this species
- Avoid frequent and very hot fires in areas with known populations.
- Identify and fence populations on roadsides to protect them during road-works.
- Protect known populations from cattle and cultivation, by fencing.
- Control introduced weeds, particularly grasses, in areas of habitat.
- Protect existing and potential habitat from clearing or development.
