Grevillea juniperina, commonly known as juniper- or juniper-leaf grevillea or prickly spider-flower, is a plant of the family Proteaceae native to eastern New South Wales and south-eastern Queensland in Australia. Scottish botanist Robert Brown described the species in 1810, and seven subspecies are recognised. One subspecies, G. j. juniperina, is restricted to Western Sydney and environs and is threatened by loss of habitat and housing development.
Pultenaea juniperina, or prickly bush-pea, is a plant of the family Fabaceae native to Eastern Australia. It is a shrub to 3 metres sporting showy yellow-orange flowers with red markings. The leaves are 10 – 25 mm long and 1 – 4 mm wide with a pungent leaf apex (stiff pointy tip), hence the use of "Prickly" in the common name. It is widespread and common in heaths, sclerophyll forests and woodlands in Eastern Australia and Tasmania.
Leptecophylla juniperina is a species of flowering plant in the family Ericaceae. The species is native to New Zealand and the Australian states of Tasmania and Victoria. The plant's fruit is edible, raw or cooked. Plants grow best in areas with moderate winters and cool moist summers.
Taxandria juniperina commonly known as wattie, native cedar, Warren River cedar or juniper myrtle is a species of tree that grows in the south west corner of Western Australia. This plant was previously classified as Agonis juniperina but is now part of the genus Taxandria . The Noongar peoples know the tree as watti.
Persoonia juniperina, commonly known as the prickly geebung, is a shrub native to south-eastern Australia. It was first collected in Tasmania, and described by French naturalist Jacques Labillardière in 1805. Within the genus Persoonia , P. juniperina is classified in the lanceolata group, a group of 54 closely related species with similar flowers but very different foliage. These species will often interbreed with each other where two members of the group occur. The species itself is variable across its range and separate subspecies have been recognised in the past, although the latest consensus is that the change is uniform enough not to warrant status for subspecies. It grows as a small spreading shrub 0.3 to 2 m (0.98 to 6.56 ft) high, and has smooth bark, hairy new branches and leaves. The narrow leaves measure 0.8 to 3.5 cm (0.31 to 1.38 in) long, and 1.5 mm wide and are linear in shape. The yellow flowers appear in summer and autumn (December to May). As with all persoonias, the flowers are followed by the appearance of small fleshy fruit. These may have been eaten by aborigines. A field study manipulating pollination showed P. juniperina was partly self-compatible but cross-pollination led to greater fruit production.
