Grevillea bipinnatifida, commonly known as fuchsia grevillea,

endemic to the south-west of Western Australia. It is a spreading shrub, usually with bipinnatifid
leaves and loose clusters of dull pink to crimson flowers.

Description

Grevillea bipinnatifida is a spreading shrub that typically grows to a height of 0.25–1.0 m (9.8 in – 3 ft 3.4 in). Its leaves are usually bipinnatifid, 40–150 mm (1.6–5.9 in) long with six to eighteen lobes, the end lobes usually triangular, 3–20 mm (0.12–0.79 in) long and 5–10 mm (0.20–0.39 in) wide and sharply pointed. The flowers are arranged along a rachis 400–200 mm (15.7–7.9 in) long and are dull pink to crimson, sometimes pale green or pale orange and the pistil is 34–42 mm (1.3–1.7 in) long. Flowering mainly occurs from June to December and the fruit is a woolly-hairy follicle 17–21 mm (0.67–0.83 in) long.[3][4]

Taxonomy

Grevillea bipinnatifida was first formally described in 1830 by

Supplementum primum prodromi florae Novae Hollandiae from specimens collected by Charles Fraser near the Swan River in 1827.[5][6] The specific epithet (bipinnatifida) means "bipinnatifid", referring to the leaves that are pinnatifid, the parts themselves pinnatifid.[7]

In 2004, Raymond Cranfield described two subspecies in the journal Nuytsia, and the names are accepted by the Australian Plant Census:

  • Grevillea bipinnatifida R.Br. subsp. bipinnatifida[8] has primary leaf lobes 5–7 mm (0.20–0.28 in) wide;[9]
  • Grevillea bipinnatifida subsp. pagna Cranfield[10] has primary leaf lobes 1–3 mm (0.039–0.118 in) wide.[9]

Distribution and habitat

Fuchsia grevillea grows in heath, open forest and woodland between

Waroona where it grows in shrubland.[9]

Conservation status

Grevillea bipinnatifida is currently listed as Least Concern on the IUCN Red List of Threatened Species due to its wide distribution, a presumed stable population and no known threats, either current or in the near future. The species seems to be unaffected by dieback disease caused by the plant pathogen Phytophtora, as it occurs in many areas which are badly impacted by it.[1]

Cultivars

Hybrid

cultivars have been produced which have Grevillea bipinnatifida as a parent species. These include hybrids with Grevillea banksii
such as:

Other hybrids include:

  • G. 'Molly' (a cross with G. aurea)
  • G. 'Sunrise' (a cross with G. 'Clearview Robin')
