Prionotes is a genus of flowering plants endemic to Tasmania, with a single species, Prionotes cerinthoides. [2] Commonly known as climbing heath, it is a temperate rainforest climber or a small scrambling shrub in the mountains. It usually lives in very wet, undisturbed places.

Description [3] [4]

Its wiry stem is about 1 meter long. The glossy deep green leaves are 0.8–2 cm long, fairly crowded, elliptical in shape with shallowly-toothed margins, without parallel veins. The deep pink tubular flowers are bell shaped with 5 petals. They are up to 2.5 cm long by 1-1.2 cm wide, and constricted at the mouth. They are pendent, often clustered, and usually appear in summer and autumn. The fruit is a woody capsule, opening by 5 valves with many seeds in each part. P. cerinthoides is self-compatible and bird pollinated.

Habitat and distribution

The plant family Ericaceae (heaths and heathers) is widespread in many parts of the globe, particularly Europe and South Africa. It contains a number of widely cultivated plants such as Erica, Rhododendron and Pieris. Like most of Australia's members of the Ericaceae, Prionotes belongs to the subfamily Epacridoideae, which was formerly classified as a separate family, the Epacridaceae. Prionotes consists of the single species, P.cerinthoides, which is endemic to Tasmania. [4] Prionotes cerinthoides is endemic to temperate rainforest, subalpine, and alpine plant communities in Tasmania, Australia.

Prionotes cerinthoides is a slender, perennial climbing or epiphytic shrub that can climb the trunk, especially the Nothofagus cunninghamii. [5] Prionotes cerinthoides is common in the rainforests of the west and south-west particularly montane areas and also occurs in alpine vegetation. This species grows best in acid soil (pH 4–5) and a cool, moist, shaded site is essential. It is sometimes referred to as the missing link between the family Epacridaceae (southern hemisphere heath family) and the Ericaceae (northern hemisphere heath family). The closest relative to Tasmania's climbing heath is a species found in the rainforests of Chile. [6]

The reproduction of Prionotes cerinthoides seems to be heavily dependent on a native bird species, the eastern spinebill (Acanthorhynchus tenuirostris). Because the nectar and pollen are sticky, Prionotes cerinthoides is not suitable for wind-pollination. At the same time, most bees rarely access this species due to the special shape of the corolla mouth. Currently, Prionotes cerinthoides is well preserved in the Tasmanian Wilderness World Heritage Area and other national parks in Tasmania, which means some habitat is moderately protected. The eastern spinebill, which can help pollination, is widely distributed.

<span class="mw-page-title-main">Ecology of Tasmania</span>

The biodiversity of Tasmania is of exceptional biological and paleoecological interest. A state of Australia, it is a large South Pacific archipelago of one large main island and a range of smaller islands. The terrain includes a variety of reefs, atolls, many small islands, and a variety of topographical and edaphic regions on the largest island, all of which promote the development of unusually concentrated biodiversity. During long periods geographically and genetically isolated, it is known for its unique flora and fauna. The region's climate is oceanic.

It is distinguishable as a prostrate, mat-like shrub, growing in rocky or boggy alpine areas. The fruit is edible and is a food source for many species of bird.

<i>Monotoca scoparia</i> Species of tree

Monotoca scoparia, commonly known as prickly broom heath, is a widespread native species across south-eastern Australia. Monotoca scoparia was formerly in the family Epacridaceae but now belongs to the family Ericaceae. Monotoca is an endemic Australian genus with 17 described species occurring in all states.

Tasmania can be broadly divided into two distinct regions, eastern and western, that exhibit major differences in climate, geology and vegetation. This divide, termed Tyler’s Corridor, runs from just south of the northwestern corner, and continues south, cutting roughly down the center of the island. The vegetation changes occur principally due to variations in soil types, which are a result of the geological composition, and the vast difference in climate across the state. Generally, the west has a higher mean rainfall but poor acidic soil while the east has a lower mean rainfall but slightly more fertile soil. This results in a larger proportion of rainforest, moorland and wet sclerophyll vegetation dominating in the west and predominantly dry sclerophyll in the east.
