Bellendena montana | |
Bellendena montana, commonly known as mountain rocket, is a species of low-growing multi-stemmed shrub in the plant family Proteaceae. It is endemic to high-altitude subalpine and alpine regions in Tasmania, Australia. The prominent white flower spikes appear over summer, followed by small bright red or yellow fruit in late summer and autumn.
Described by Robert Brown in 1810, it is the sole member of the genus Bellendena, which is in turn the sole member of subfamily Bellendenoideae, and is thought to represent an early offshoot within the family. [3]
Scottish botanist Robert Brown described the mountain rocket in 1810 as Bellendena montana, [4] naming the genus in honour of John Bellenden Ker Gawler for his botanical works. The species name is the Latin adjective montanus and refers to its montane habitat. [5] Its common name refers to its red-tipped rocket-shaped flowerheads. [5]
Phylogenetic studies often place this genus as basal (one of the earliest offshoots) to the rest of the Proteaceae, though its exact position and relationships are unclear. A 2006 analysis, synthesizing molecular and other studies, by Weston and Barker [3] located it as sister to the subfamily Persoonioideae, the two sharing a common ancestor which diverged from the other Proteaceae. However, the genus has an anatomical feature, laterocytic stomata (having 3 or more parallel specialised subsidiary cells), which it shares with the Platanaceae (next closest relatives to the Proteaceae) and no other Proteaceae, which indicate it diverged from all other members of the family first. [3]
Bellendena montana grows as a low, spreading multistemmed shrub to anywhere from 10 cm to 1.8 m high, [4] and 1 m in diameter. The leaves are thick and variable, [5] ranging from oblanceolate to spathulate to wedge-shaped (cuneate) in shape with recurved margins and measuring 1–6 cm long and 0.2 to 2.2 cm wide. Plants from north-eastern Tasmania have narrower leaves than elsewhere, and populations from higher altitudes have smaller leaves and more crowded foliage. [4] The flowers occur in terminal racemes which are held on short stems above the foliage. [5] These are followed by small egg-shaped (obovate) bright red or yellow fruit, which are ripe in late summer and autumn. [6]
Bellendena montana is found at altitudes above 1000 m (3500 ft), though rarely lower to 400 m. [4] It grows on low-nutrient soils (mostly dolerite, but sometimes quartzite or basalt-derived [4] ) with good drainage, often rocky outcrops, [6] as well as more boggy areas and alpine heathland. [4]
The plant has attractive flowers, fruit and foliage, but is not often cultivated because it is difficult to grow at low altitudes. Propagation by seed or cutting is unreliable. [7]
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.
Persoonia micranthera, commonly known as the small-flowered snottygobble, is a species of flowering plant in the family Proteaceae and is endemic to a restricted area in the south-west of Western Australia.

Alloxylon pinnatum, known as Dorrigo waratah, is a tree of the family Proteaceae found in warm-temperate rainforest of south-east Queensland and northern New South Wales in eastern Australia. It has shiny green leaves that are either pinnate (lobed) and up to 30 cm (12 in) long, or lanceolate (spear-shaped) and up to 15 cm (5.9 in) long. The prominent pinkish-red flower heads, known as inflorescences, appear in spring and summer; these are made up of 50 to 140 individual flowers arranged in corymb or raceme. These are followed by rectangular woody seed pods, which bear two rows of winged seeds.
Persoonia levis, commonly known as the broad-leaved geebung, is a shrub native to New South Wales and Victoria in eastern Australia. It reaches 5 m (16 ft) in height and has dark grey papery bark and bright green asymmetrical sickle-shaped leaves up to 14 cm (5.5 in) long and 8 cm (3.2 in) wide. The small yellow flowers appear in summer and autumn, followed by small green fleshy fruit, which are classified as drupes. Within the genus Persoonia, it is a member of the Lanceolata group of 58 closely related species. P. levis interbreeds with several other species where they grow together.
Persoonia linearis, commonly known as the narrow-leaved geebung, is a shrub native to New South Wales and Victoria in eastern Australia. It reaches 3 m (9.8 ft), or occasionally 5 m (16 ft), in height and has thick, dark grey papery bark. The leaves are, as the species name suggests, more or less linear in shape, and are up to 9 cm (3.5 in) long, and 0.1 to 0.7 cm wide. The small yellow flowers appear in summer, autumn and early winter, followed by small green fleshy fruit known as drupes. Within the genus Persoonia, it is a member of the Lanceolata group of 58 closely related species. P. linearis interbreeds with several other species where they grow together.
