Grevillea speciosa, also known as Red Spider Flower, is a shrub which is endemic to New South Wales in Australia.
This species is a shrub, growing up to 3 metres in height. Its leaves are narrow-obovate to round or elliptic to narrow-elliptic . The flowers which are red, or occasionally pink, appear predominantly from late winter to late spring (August to November in Australia) but appear sporadically throughout the year.
The species occurs in Sydney
and the surrounding area in moist areas within dry sclerophyll
woodland or heathland.
The species was first formally described in James Edward Smith
's 1793 A Specimen of the Botany of New Holland
as Embothrium sericeum
. In 1809 the plant was rediscovered, and [[Joseph Knight] (gardener)|]] published it as Lysanthe speciosa
, not realising that his material was attributable to Smith's E. sericeum
. In 1975 the species was transferred into Grevillea
as G. speciosa
. Smith's precedence would not be discovered until 2000.
