Grevillea dryandri is a species of flowering plant in the familyProteaceae and isendemic to northern Australia. It is a spreading to erect shrub with divided leaves with up to seventy or more linear to narrowly elliptic leaves, and long clusters of red, orange-red, pink or white flowers.
Grevillea dryandri is a spreading to erect shrub that typically grows to a height of 0.3–2 cm (0.12–0.79 in). It has divided leaves 40–280 mm (1.6–11.0 in) long with mostly ten to sixty linear to narrowly lance-shaped lobes 40–210 mm (1.6–8.3 in) long and 0.7–3 mm (0.028–0.118 in) wide with the edges turned down or rolled under. The lower surface of the leaflets is silky-hairy. The flowers are arranged in clusters, therachis 100–600 mm (3.9–23.6 in) long, each flower on apedicel 4.5–10 mm (0.18–0.39 in) long. The flowers are red, orange-red, pink or white, thepistil 41–50 mm (1.6–2.0 in) long. Flowering time depends on subspecies and the fruit is a thin-walledfollicle 7.5–15 mm (0.30–0.59 in) long.[3][4]
Grevillea dryandri was first formally described in 1810 byRobert Brown in theTransactions of the Linnean Society of London from specimens collected inArnhem Land.[5][6] Thespecific epithet (dryandri) honoursJonas Carlsson Dryander.[7]
In 1986,Donald McGillivray described two subspecies ofG. dryandri and the names are accepted by theAustralian Plant Census:
Subspeciesdasycarpa grows in shrubby woodland on sandstone betweenMataranka,Daly River and theGove Peninsula in the northern part of the Northern Territory.[9][10] Subspeciesdryandri grows in open woodland or open shrubland, often in rocky places, from theKimberley region of Western Australia, to the Northern Territory north of aboutTennant Creek and to northern parts of Queensland, mainly as far asMount Isa andNormanton.
Grevillea dryandri is listed asLeast Concern on theIUCN Red List of Threatened Species, due to it being a widely distributed, locally common species with no major threats affecting its population.[1] Both subspecies ofG. dryandri are listed as of "least concern" under the Northern Territory GovernmentTerritory Parks and Wildlife Conservation Act.[10][13]
