Distribution of Ozothamnus rodwayi from Atlas of Living Australia

Ozothamnus rodwayi, commonly known as alpine everlastingbush (and formerly known as Helichrysum backhousii [1] ), is a species of flowering plant in the family Asteraceae that is endemic to Tasmania, Australia. It is a widespread small, dense alpine shrub abundantly found in alpine and high subalpine heaths and woodlands.

Contents

Description [2] [3]

Ozothamnus rodwayi is a small and compact, highly branched rounded shrub in the family Asteraceae, and is one of 54 species from the genus Ozothamnus. Typically it grows 50–100 cm in height and 50–80 cm in width. Ozothamnus rodwayi is distinguished from other members of its genus by its tiny (7-15mm long), grey/green leaves with a densely hairy-white underside, that are obovate and alternately arranged. Young foliage of the plant has a slightly sticky feel. Like other members of the family Asteraceae it has white daisy flowers; these are arranged in compact terminal, profuse clusters, and are distinguished by brown hairy bracts. As with all members of the family Asteraceae, its fruit is a cypsela; these have two fused carpels yet only one locule, which produces one seed per formed fruit.

Taxonomy

Species variations

There are three species variations of Ozothamnus rodwayi which are currently recognised by the Australian Plant Census:

Habitat and distribution [2]

Ozothamnus rodwayi is widespread and abundant in areas of high altitude throughout Tasmania, Australia, to which it is endemic. It is common on exposed alpine slopes to subalpine heath and woodlands, such as at Cradle Mountain-Lake St Clair National Park, Mount Field National Park and throughout the Central Highlands (Tasmania).

Cultivation [2]

Requires full sun in moist, well drained soil with a high humus content. Ozothamnus rodwayi can be used as an attractive shrubbery, rockery or container plant and can be propagated from seed or cuttings.

<i>Orites revolutus</i> Species of plant in the family Proteaceae endemic to Tasmania

Orites revolutus , also known as narrow-leaf orites, is a Tasmanian endemic plant species in the family Proteaceae. Scottish botanist Robert Brown formally described the species in Transactions of the Linnean Society of London in 1810 from a specimen collected at Lake St Clair. Abundant in alpine and subalpine heath, it is a small to medium shrub 0.5 to 1.5 m tall, with relatively small, blunt leaves with strongly revolute margins. The white flowers grow on terminal spikes during summer. Being proteaceaous, O. revolutus is likely to provide a substantial food source for nectivorous animal species within its range.
