Grevillea obtusiflora

Status: Endangered on the EPBC Act list

The two subspecies differ primarily in leaf size and shape. Grevillea obtusiflora subsp. obtusiflora
G. obtusiflora subsp. obtusiflora is a low, multi-stemmed shrub, growing to 0.2-0.4 m high. Its leaves are narrowly obtuse-elliptic to oblong, and 2-5 cm long and 1.5-5 mm wide. Flowers are pink to pinkish red and cream. It flowers sparsely in winter and spring, between July and October, with flowering peaking in September. It is not known to set fruit or seed (Makinson 1997), but regenerates from root suckers.

Grevillea obtusiflora subsp. fecunda is a low, spreading to erect shrub growing up to one metre high. It flowers profusely with crimson to deep pink and cream flowers in spring. Its leaves are linear to very narrowly obovate, 1.5-4.0 cm long and 1.0-1.2 mm wide. Fruit sets freely (Makinson 1997).

    Fire Fire potential future Despite Grevillea obtusiflora having fire survival frequency strategies; fire can have a major influence on population dynamics and community composition and therefore habitat of the species.

    Germination responses may also be sensitive to fire season (Ooi et al. 2004).
