Hakea teretifolia, commonly known as the dagger hakea, [2] is a species of woody shrub of the family Proteaceae and is common on heathlands in coastal eastern Australia from northern New South Wales through to Victoria and Tasmania. A very prickly shrub, it is rarely cultivated but easy to grow.
Hakea teretifolia is a prickly shrub that can reach 3 m (10 ft) in height. It has spirally arranged, thick, tough, succulent spike-tipped leaves. Flowering occurs in summer though some may be seen in winter. The small white inflorescences occur on branches and consist of 4-8 individual small flowers. These are followed by sharp pointed (dagger-shaped) seed pods from where the plant gets its common name. [3]
Hakea teretifolia was first collected at Botany Bay in April 1770, by Sir Joseph Banks and Daniel Solander, naturalists on the British vessel HMS Endeavour during Lieutenant (later Captain) James Cook's first voyage to the Pacific Ocean. Solander coined the (unpublished) binomial name Leucadendroides corniculata in Banks' Florilegium . [4] Richard Salisbury described the species in his book Prodromus stirpium in horto ad Chapel Allerton vigentium in 1796 and gave it the name Banksia teretifolia. [5] [6] The specific epithet (teretifolia) is from the Latin teretifolium, meaning "with terete leaves". [7]
In 1797, Heinrich Schrader and Johann Christoph Wendland described the genus Hakea and the type species Hakea glabra in their book Sertum Hannoveranum. [8] [9] [10]
In 1916, James Britten changed the name of Salisbury's Banksia teretifolia to Hakea teretifolia in the Journal of Botany, British and Foreign . [11] Britten considered Schrader's Hakea glabra, Antonio José Cavanilles' Hakea pugioniformis [12] [13] and Joseph Gaertner's Conchium teretifolium [14] [15] to be synonyms. [16] The Australian Plant Census lists H. glabra, H. pugioniformis and C. teretifolium as synonyms of H. teretifolia subsp. teretifolia. [17] Hakea teretifolia was classified in Hakea sect. Hakea series Pubiflorae by George Bentham in his Flora Australiensis , [18] but was reclassified on its own in the Teretifolia group in the 1999 Flora of Australia treatment. [3]
In 1990, Robyn Mary Barker described two subspecies of H. teretifolia in the Journal of the Adelaide Botanic Gardens , and the names are accepted by the Australian Plant Census: [19]
Subspecies teretifolia ranges from Coffs Harbour south through the Sydney region to the Budawang Range in New South Wales.
Subspecies hirsuta occurs further south from the Sydney region through to Tasmania with a separate population in the Grampians in western Victoria. It is found on sandstone soil-based heathland, and can form dense thickets with the heath banksia ( Banksia ericifolia ) and scrub she-oak ( Allocasuarina distyla ). It grows in moist to wet locations in heath and woodlands east of Melbourne and a disjunct population in the Grampians. [21] [22]
Hakea teretifolia is rarely cultivated but is an easy plant to grow provided it has a sunny aspect. Unlike many other proteaceae it can be tolerant of poor drainage. Its extremely prickly foliage can make a good deterrent. When planted in clumps, this species provides an excellent shelter for small birds such as superb fairywrens (Malurus superbus) and the smaller sized honeyeaters. It can also prove a prickly deterrent for burglars. [2] [23]
Hakea is a genus of about 150 species of plants in the Family Proteaceae, endemic to Australia. They are shrubs or small trees with leaves that are sometimes flat, otherwise circular in cross section in which case they are sometimes divided. The flowers are usually arranged in groups in leaf axils and resemble those of other genera, especially Grevillea. Hakeas have woody fruit which distinguishes them from grevilleas which have non-woody fruit which release the seeds as they mature. Hakeas are found in every state of Australia with the highest species diversity being found in the south west of Western Australia.
Xylomelum is a genus of six species of flowering plants, often commonly known as woody pears, in the family Proteaceae and are endemic to Australia. Plants in this genus are tall shrubs or small trees with leaves arranged in opposite pairs, relatively small flowers arranged in spike-like groups, and the fruit a woody, more or less pear-shaped follicle.
Banksia laevigata, commonly known as the tennis ball banksia, is a species of shrub that is endemic to Western Australia. It has serrated, broadly linear to narrow wedge-shaped leaves, yellow or yellowish green flowers, depending on subspecies, and linear to elliptic follicles with a slightly wrinkled surface.
Banksia paludosa, commonly known as the marsh or swamp banksia, is a species of shrub in the plant genus Banksia. It is native to New South Wales, Australia, where it is found between Sydney and Batemans Bay, with an isolated population further south around Eden. There are two recognised subspecies, the nominate of which is a spreading shrub to 1.5 m (4.9 ft) in height, and subsp. astrolux is a taller shrub to 5 m (16 ft) high found only in Nattai National Park.
Hakea corymbosa, commonly known as the cauliflower hakea is a plant of the family Proteaceae which is endemic to the south-west of Western Australia. An attractive extremely prickly bush with sweetly scented yellowish flowers. The nectar rich blooms and dense form provides a good habitat for wildlife.
The taxonomy of Banksia integrifolia has a long and complex history, the result of confusion caused by the species' great variability, and similarities with some closely related species. The existence of hybrids between B. integrifolia and related species as well as early attempts to classify the species based on dried specimen material have also contributed to the confusion.
Banksia integrifolia subsp. integrifolia is a subspecies of Banksia integrifolia.
Banksia integrifolia subsp. compar is a subspecies of Banksia integrifolia. It has larger, glossier leaves than other subspecies, and occurs much further north.
Banksia bipinnatifida is a species of shrub that is endemic to Western Australia. It is a prostrate shrub with a lignotuber, an underground stem, only a few divided leaves, large cream-coloured to pale yellow flowers and large fruit.
Banksia rufa is a species of prostrate shrub that is endemic to the south-west of Western Australia. It has broadly linear, pinnatifid or pinnatipartite leaves with between five and twenty lobes on each side, yellow, orange or brownish flowers in heads of forty or more, and glabrous, egg-shaped follicles.
Banksia hirta is a species of shrub that is endemic to Western Australia. It has hairy stems, deeply serrated leaves, pale yellow flowers in heads of about one hundred and shining follicles. It is restricted to the Stirling Range National Park.
Banksia horrida, commonly known as prickly dryandra, is a species of shrub that is endemic to Western Australia. It has hairy stems, linear, pinnatifid leaves with sharply pointed teeth on the edges, up to sixty cream-coloured flowers in each head and hairy, egg-shaped follicles.
Banksia ionthocarpa is a species of shrub that is endemic to Western Australia. It has short, hairy, prostrate stems, pinnatifid leaves, pinkish purple to orange flower in heads of between forty and sixty at the base of leaves, and egg-shaped follicles with a distinctive tuft of hairs on the end.
Banksia splendida, commonly known as shaggy dryandra, is a species of shrub that is endemic to the southwest of Western Australia. It has sharply-pointed linear leaves that are woolly on the lower surface, cream-coloured and maroon or yellow flowers in heads of between 65 and 115, and later up to eight egg-shaped follicles in each head.
Banksia squarrosa, commonly known as pingle, is a species of prickly shrub that is endemic to Western Australia.

It has very prickly foliage, cream-yellowish flowers from April to July, and provides shelter for small birds.
