• Taxonomy

• This species was first formally described in 1794 by James Edward Smith who gave it the name Embothrium sericeum in his book, A Specimen of the Botany of New Holland.[6][7] In 1810, Robert Brown transferred it into Grevillea as G. sericea in Transactions of the Linnean Society of London

• In 1994, Peter M. Olde and Neil R. Marriott described two subspecies of G. sericea in The Grevillea Book, and the names are accepted by the Australian Plant Census:

• 
  

• Grevillea sericea subsp. riparia (R.Br.) Olde & Marriott[9] has linear leaves 60–120 mm (2.4–4.7 in) long, 1–3 mm (0.039–0.118 in) wide, and purplish pink flowers usually amongst the leaves.[10][11]

• Grevillea sericea (Sm.) R.Br. subsp. sericea[12] has egg-shaped leaves with the narrower end towards the base, to elliptic or narrowly elliptic leaves, usually less than 30 mm (1.2 in) long, 3–9 mm (0.12–0.35 in) wide, and deep to pale pink or white flowers usually mostly above the foliage.[13][14]

• Distribution and habitat

• Pink spider flower is widespread in New South Wales, and grows in woodland and open forest from near Toronto and Wyee south to near Heathcote, and inland to near Mudgee.[4][13][14] Subspecies riparia has a more restricted distribution, growing near permanent streams mainly near the escarpment of the Blue Mountains, along the Grose and Colo Rivers and Glenbrook Creek.
