An adaptable, fast growing small tree or shrub with attractive foliage and cream white flowers. DescriptionHakea salicifolia is a fast-growing upright shrub or small tree to {{convert|3-5|m|ft|sigfig=1|abbr=on}} tall. Smaller branches are smooth with obvious dark red longitudinal ribbing. Young shoots have sparse silky hairs or may be totally hairless. Leaves are narrowly oval shaped,widest in the middle up to 12 cm long and {{convert|5-20|mm|in|sigfig=1|abbr=on}} wide tapering to a point or occasionally rounded at the apex. The pale green leaves are smooth, occasionally bluish-green with a powdery film. Young leaves are darker with sparse flattened silky white and rusty coloured hairs quickly becoming smooth. The inflorescence consists of a single umbel of 16-28 white to pale yellow flowers on a short stalk {{convert|1-1.5|mm|in|sigfig=1|abbr=on}} long. The young flower bracts {{convert|3|mm|in|sigfig=1|abbr=on}} long and slightly hairy externally. The pedicel is {{convert|4.5-7|mm|in|sigfig=1|abbr=on}} long. The perianth smooth, bluish-green with a powdery film and {{convert|2.3-3.5|mm|in|sigfig=1|abbr=on}} long. The style {{convert|6-6.5|mm|in|sigfig=1|abbr=on}} long. Egg-shaped fruit are {{convert|2.3-3.5|cm|in|sigfig=1|abbr=on}} long and {{convert|1.3-3|cm|in|sigfig=1|abbr=on}} wide narrowing gradually to a slightly upturned beak with small horns. The fruit surface is covered with black blister-like warts {{convert|1-5|mm|in|sigfig=1|abbr=on}} high.[1][2][3]Taxonomy and namingWillow-leaved hakea was first formally described in 1800 by French botanist Étienne Pierre Ventenat who gave it the name Embrothium salicifolium and published the description in Description des Plantes Nouvelles et peu connues, cultivees dans le Jardin de J.M. Cels. The type specimen was grown in the garden of Jacques Philippe Martin Cels from material collected from Botany Bay in 1792.[4][5] In 1941 English botanist Brian Burtt changed the name to Hakea salicifolia and published the description in Bulletin of Miscellaneous Information.[6] The specific epithet (salicifolia) is derived from the Latin words salix[7]{{rp|174}} meaning "willow" and folius meaning "leaved"[7]{{rp|46}} referring to the willow-like leaves.[8] Two sub-species are currently recognised:
Distribution and habitatHakea salicifolia is a widespread species growing mainly from Kempsey to the Shoalhaven River, Dorrigo, Whian Whian and the Blue Mountains. Also found near the Queensland and New South Wales border. Grows in wet sclerophyll forest often near rainforest.[3][9]EcologyWillow-leaved Hakea is an invasive plant species in New Zealand and is listed by the New Zealand Department of Conservation as one of about 300 environmental weeds. An attractive ornamental tree adaptable to most soils and aspects from sub-tropical to temperate zones creating issues with over abundance of the species in some localities. Planted on tea plantations in Tanzania as a wind-break and boundary hedge.[2][10][11] {{-}}References1. ^{{cite book |last1=Holliday |first1=Ivan |title="Hakeas a Field and Garden Guide" |publisher=Reed New Holland |isbn=1-877069-14-0}} 2. ^1 {{cite book |last1=Wriggley |first1=John W. |last2=Fagg |first2=Murray |title="Australian Native Plants-Propagation, cultivation and use in landscaping" |date=1996 |publisher=Reed New Holland |isbn=1-876334-30-4}} 3. ^1 2 {{cite book |last1=Wilson (ed) |first1=Annette |last2=Barker |first2=Robyn M. |last3=Haegi |first3=Laurence A. |last4=Barker |first4=William R. |title="Flora of Australia" Vol.17B Proteaceae 3 Hakea to Dryandra |date=1999 |publisher=ABRS |isbn=0-643-06454-0}} 4. ^{{cite web|title=Embothrium salicifolium|url= https://id.biodiversity.org.au/instance/apni/543975|publisher=APNI|accessdate=5 February 2019}} 5. ^{{cite book |last1=Ventenat |first1=Etienne Pierre |title=Description des plantes nouvelles et peu connues : cultivées dans le jardin de J.M.
