Grevillea shiressii, Family Proteaceae, is an erect shrub 1.5Ð5 m high, with flowers bluish to mauve at the base and along the dorsal side, creamy white elsewhere. The style is dull, purplish red or brown-maroon, with green tip and ovary (Olde & Marriott, 1995; Makinson, 2000). Flowers are pollinated by honeyeaters and appear mainly between July and December (McGillivray & Makinson, 1993; Olde & Marriott, 1995; Benson & McDougall, 2000; Makinson, 2000). Seed is released at maturity in October and is dispersed by ants (DECC, 2005).

Threats The main identified threats to G. shiressii are inappropriate fire regimes incursions of pathogens; such as Phytophthora cinnamoni and habitat loss or degradation.
The main potential threats are that G. shiressii is fire frequency; as it is killed by fire and regenerates only from seed (McGillivray Makinson; 1993 Olde Marriott; 1995 Benson McDougall; 2000 Makinson; 2000).
