Zieria aspalathoides, commonly known as the whorled zieria, heath zieria, hairy zieria or heathy zieria, [2] is a plant in the citrus family Rutaceae and is endemic to eastern Australia. It is a heath-like shrub with leaves that appear to be whorled and with pink flowers in groups of three, each with four petals and four stamens.
Zieria aspalathoides is a heath-like shrub which grows to a height of between 1 and 1.5 m (3 and 5 ft) with branches that are ridged and scaly or hairy, at least when young. The leaves are composed of three linear to lance-shaped leaflets 5–8 mm (0.2–0.3 in) long and 1–1.3 mm (0.04–0.05 in) wide. The leaves have a stalk less than 1 mm (0.04 in) long and are arranged in opposite pairs, so that there appears to be a whorl of six simple leaves. The edges of the leaflets are rolled under and the upper surface is a darker green than the lower one. [2] [3] [4]
The flowers are pale to deep pink and are arranged in groups of mostly three, the groups usually longer than the leaves. The sepals are triangular, about 1.4 mm (0.06 in) long and usually smooth but hairy. The four petals are 4–5.5 mm (0.16–0.22 in) long, overlap at the edges and are covered with short, soft hairs and there are four stamens. Flowering occurs from late winter to early summer and is followed by the fruit which is a mostly glabrous follicle containing black seeds. [2] [3] [4]
Zieria aspalathoides was first formally described in 1863 by George Bentham from an unpublished description by Allan Cunningham. Bentham's description was published in Flora Australiensis. [1] [4] The specific epithet (aspalathoides) refers to a perceived similarity to plants in the genus Aspalathus - the suffix -oides means "likeness" in Latin. [5]
Two subspecies have been described:
This zieria occurs in Queensland, New South Wales and Victoria, growing in dry forest heath, usually in sandy soil and often between rocks. Subspecies aspalathoides is widespread from Victoria to the Atherton Tableland in Queensland, although it only occurs in a few scattered populations in Victoria. In New South Wales it occurs on the tablelands and western slopes. Subspecies brachyphylla only occurs on the Blackdown Tableland in Queensland. [2] [3] [7]
Zieria smithii, commonly known as sandfly zieria, lanoline bush or Smithian zieria, is a plant in the citrus family Rutaceae and is endemic to eastern and south-eastern Australia. It is a robust shrub with its leaves composed of three leaflets, and groups of flowers with four white petals, the groups usually shorter than the leaves. It is common and widespread along the coast and adjacent ranges.
Zieria granulata, commonly known as the Illawarra zieria, hill zieria or hilly zieria, is a plant in the citrus family Rutaceae and is endemic to the Illawarra region of New South Wales. It is a tall, bushy shrub distinguished by the wart-like tubercles that cover the entire plant, its linear leaflets and small white, four-petalled flowers.
Zieria arborescens, commonly known as the tree zieria or stinkwood, is a plant in the citrus family Rutaceae and is endemic to eastern Australia. It is a bushy shrub or small tree with branches that are ridged and scaly or hairy, at least when young. It has leaves composed of three leaflets and groups of flowers with four white petals, the groups usually shorter than the leaves.
Boronia anemonifolia, commonly known as narrow-leaved boronia or sticky boronia, is a flowering plant that is endemic to south-eastern Australia. It is a shrub with mostly pinnate leaves, with white to pale pink four-petalled flowers in leaf axils.
Zieria minutiflora, commonly known as twiggy zieria, is a plant in the citrus family Rutaceae and is endemic to eastern Australia. It is a small, erect, twiggy shrub with leaves composed of three leaflets, and clusters of small white flowers with four petals and four stamens. It usually grows as an understorey shrub in eucalypt woodland.
Zieria floydii, commonly known as the Floyd's zieria, is a plant in the citrus family Rutaceae and is endemic to the New England Tableland in New South Wales. It is an erect shrub with warty, hairy branches, three-part, clover-like leaves and clusters of creamy-white flowers with four petals and four stamens.
Zieria fraseri is a plant in the citrus family Rutaceae and is endemic to eastern Australia. It is a dense, bushy shrub with leaves composed of three leaflets, and white flowers with four petals and four stamens. It usually grows in rocky places on steep hills.
Zieria furfuracea is a plant in the citrus family Rutaceae and is endemic to eastern Australia. It is a shrub with three-part leaves and groups of large numbers of small white flowers, the groups shorter than the leaves. It grows on the coast and tablelands north from Wyong.
Zieria inexpectata is a plant in the citrus family Rutaceae and endemic to south-eastern Queensland. It is a small, compact shrub with erect, wiry branches, three-part leaves and groups of up to twelve white flowers, the groups longer than the leaves and the flowers with four petals and four stamens. It was unexpectedly discovered by the authors during a field trip and its discovery led to a paper describing the zierias of Queensland, including sixteen new species.
Zieria insularis is a plant in the citrus family Rutaceae and endemic to tropical north-eastern Queensland. It is an open, straggly shrub with wiry or spindly branches, three-part leaves and between one and a few white flowers with four petals and four stamens arranged in the leaf axils. It mostly grows near granite outcrops which are surrounded by forest or rainforest.
Zieria involucrata is a plant in the citrus family Rutaceae and is endemic to New South Wales. It is a sparse, erect shrub with mostly three-part leaves and groups of up to 21 small white flowers, the groups shorter than the leaves. It mostly occurs in the lower Blue Mountains, but is also known from other areas around Sydney.
Zieria laxiflora, commonly known as wallum zieria, is a plant in the citrus family Rutaceae and is endemic to eastern Australia. It is an erect shrub with leaves composed of three leaflets, and clusters of about nine white or pale pink flowers with four petals and four stamens. It usually grows is coastal heathland.
Zieria obovata is a plant in the citrus family Rutaceae and is endemic to Queensland. It is a small, open shrub with leaves composed of three leaflets, and with up to three cream-coloured to pale pink flowers with four petals and four stamens. It usually grows on steep, rocky slopes in wet open forest.
Zieria odorifera, commonly known as the fragrant zieria, is a plant in the citrus family Rutaceae and is endemic to inland New South Wales. It is an aromatic shrub with ridged branches, leaves composed of three leaflets and groups of mostly three pale to deep pink, four-petalled flowers in spring.
Zieria rimulosa is a plant in the citrus family Rutaceae and is endemic to north Queensland. It is a shrub with leaves composed of three leaflets, and with white flowers with four petals and four stamens. Unlike many other zierias, its leaves are neither rough, glandular or densely hairy.

Zieria veronicea, commonly known as the pink zieria, is a plant in the citrus family Rutaceae and is endemic to south-eastern Australia. It is a small, lemon-scented shrub densely covered with velvety hairs. Up to three flowers with four pink petals appear in leaf axils in late spring.
Zieria whitei is a plant in the citrus family Rutaceae and is endemic to a small area of north Queensland.
