Grevillea parviflora is a dense, spreading to erect shrub that typically grows to a height of 1 m (3 ft 3 in) or less and sometimes forms a rhizome. Its leaves are more or less linear, mostly 15–35 mm (0.59–1.38 in) long and 0.8–1 mm (0.031–0.039 in) wide with the edges turned down or rolled, the lower surface silky hairy when visible. The flowers are arranged in groups of 4 to 14 on the ends of branches, the groups usually shorter than the nearby leaves. The flowers are white with rust-coloured hairs, the style sometimes turning red with age, the pistil usually 4.5–6.5 mm (0.18–0.26 in) long. Flowering occurs from July to December and the fruit is a glabrous, warty follicle 8–10 mm (0.31–0.39 in) long.[3][4]

Grevillea parviflora was first formally described in 1810 by Robert Brown in Transactions of the Linnean Society of London.[5][6] The specific epithet (parviflora) means "small-flowered".[7]
In 2000, Robert Owen Makinson described two subspecies of G. parviflora in the Flora of Australia, and the names are accepted by the Australian Plant Census:
- Grevillea parviflora subsp. parviflora Makinson[8] has more or less erect main branches, leaves mostly 0.8–1.3 mm (0.031–0.051 in) wide and the "stalk" of the ovary 1.0–1.2 mm (0.039–0.047 in) long.[9][10]
- Grevillea parviflora R.Br. subsp. supplicans[11] has more or less spreading main branches, leaves mostly 0.6–2 mm (0.024–0.079 in) wide and the "stalk" of the ovary 0.5–0.6 mm (0.020–0.024 in) long.[12][13]

This grevillea grows heath or shrubby or heathy woodland in the Sydney region. Subspecies parviflora is mostly found west and south of Sydney between Camden, Appin and Cordeaux Dam with disjunct populations near Putty, Cessnock and Cooranbong. Subspecies supplicans occurs north-west of Sydney near Arcadia, Maroota and Marramarra National Park.[9][10][12][13]

Subspecies parviflora is listed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and the New South Wales Government Biodiversity Conservation Act 2016 and subsp. supplicans as "endangered" under the Biodiversity Conservation Act 2016.[2][3][9][12]
