Richea angustifolia

Richea scoparia is a species of plant endemic to Tasmania. The genus Richea, forms part of the Ericaceae (formerly Epacridaceae) family, which are commonly heath-like shrubs. [3] [4] The name refers to the erect bushy growth habit, described as a broom-like shrub, most commonly referred to as the honey bush or simply scoparia to many bushwalkers. [5]

Description

Richea scoparia is 1-3m high and commonly grows in wind-swept regions of mountains. The leaves persist for a number of years, even when dead. Leaves are crowded, sharp pointed, linear-lanceolate with a broad sheathing base, 3–6 cm long. [3] [6] Inflorescences are terminal spikes 4–12 cm in varying colours of orange, yellow, red, pink or white, flowering in January- March. Flowers with caps of joined petals, which are deciduous, exposing 5mm long stamens and a short style. [6] [3]

Hybrid

Richea scoparia forms a hybrid species with Richea pandanifolia . The hybrid species, Richea curtisiae is relatively common where both R. scoparia and R. pandanifolia occur, especially after a disturbance as a result of fire or a clearing. [7]

Distribution

Richea scoparia is found in montane vegetation and is subject to harsh conditions throughout several months of the year. It occurs in the west, south-west, north-east and Central Plateau of Tasmania [4] in a variety of habitats above 700m. It is widespread in alpine regions and associated with a number of varying species. [7] R. scoparia is a slow growing, scleromorphic, perennial species with many morphological variabilities. [8] The growth habits and morphology of R. scoparia populations are influenced by the level of difference weather conditions, to which each population is exposed. [4] The exposure to wind speed and direction have a predominant effect on growth rate and success of the species, [9] [8] which grows as a dense rounded bush in highly exposed areas. [6]

Reproduction

Richea scoparia and Niveoscincus microlepidotus (snow skink) form a unique interaction, where N. microlepidotus aids in the pollination of R. scoparia by removing the calyptra (fused petal caps) of the inflorescence to feed on the nectar of the plant. [10] This exposes the reproductive parts which increases the number of seeds dispersed and pollination success of the plant. This interaction has been thought to have been an adaptation to the harsh weather conditions by evolving with the lizards feeding habits to ensure the success of calyptra removal and dispersal of seeds. [10]

The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c. 4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron, and various common heaths and heathers.

<i>Epacris impressa</i> Plant of the heath family, Ericaceae, that is native to southeast Australia

Epacris impressa, also known as common heath, is a species of plant in the heath family Ericaceae. It is native to south-eastern Australia. French botanist Jacques Labillardière collected the species in 1793 and described it in 1805. Four forms have been identified, but no subspecies are recognised. Growing in heathland, shrubland or open forest, it is generally a small shrub around 0.5 to 1 m tall, with small stiff leaves. The red, pink or white tube-like flowers appear from late autumn to early spring. Honeyeater birds, particularly the eastern spinebill, feed upon the nectar of the flowers. It regenerates after bushfire by seed or by resprouting.

<i>Epacris</i> Genus of flowering plants in the heath family Ericaceae

Epacris is a genus of about forty species of flowering plants in the family Ericaceae. It was formerly treated in a closely related but separate family Epacridaceae, but the various genera within Epacridaceae including Epacris have been revised in their relationships to each other and brought under the common umbrella of the Ericaceae. The genus Epacris is native to eastern and southeastern Australia, New Caledonia and New Zealand. The species are known as heaths or Australian heaths.

Banksia grossa is a species of shrub in the family Proteaceae and is endemic to Southwest Australia. It is one of fourteen species of banksia of the series Abietinae, all of which bear predominantly cylindrical or oval inflorescences. Collected in 1965, it was first formally described in 1981 by Alex George. Its thick leaves and large seeds distinguish it from other members of the Abietinae, and are the basis of its species name.

<i>Richea victoriana</i> Species of flowering plant

Richea victoriana is a species of flowering plant in the family Ericaceae that is endemic to Victoria, Australia. It is similar to Richea continentis, with differences including the presence of prominent leaf scars on the stems and inflorescences that are less than 12 cm long and have a hairless stem. The species was first formally described in 1995 in Muelleria based on plant material collected from the Thomson River headwaters.

<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.
