Grevillea flexuosa

Status: Vulnerable on the EPBC Act list

Grevillea flexuosa, Family Proteaceae, also known as Zig Zag Grevillea or Tangled Grevillea, is a few-branched, scraggly hairless shrub to 2 m high and 2 m wide. Branches are long, trailing and tangled, with stems changing directions at the nodes (zig-zag). Leaves are greyish-green, up to 30 cm long on vegetative branches and deeply divided into 8Ð12 or more well-spaced leaflets (Brown et al., 1998). Leaves on flowering stems are smaller (5Ð10 cm) (Olde & Marriott, 1995; Makinson, 2000). The leaves are slightly prickly (Wrigley & Fagg, 2007). Flowers are 4 cm long, cream to yellow, with a strong, sweet scent and are arranged in cylindrical racemes or candle-like spikes (Olde & Marriott, 1995; Brown et al., 1998; Makinson, 2000; Wrigley & Fagg, 2007; Western Australian Herbarium, 2008). It has been recorded as flowering from May to October (Brown et al., 1998; Western Australian Herbarium, 2008).

    Threats The main potential threats to Zig Zag Grevillea include dieback from Phytophthora cinnamomi (O Gara et al.; 2005) broad scale vegetation clearing increasing fragmentation grazing pressure weeds changed hydrology including salinisation (May McKenzie; 2003) and changed fire regimes (NLWRA; 2002).
