Calochlaena dubia, commonly known as soft bracken, false bracken, common ground fern or rainbow fern, is a small Australian fern in the treefern family Dicksoniaceae. It is very common within its range, and often seen growing under eucalyptus forest, often on the poorer quality soils. [1] It is an easy plant to grow in the garden.
One of the many plants described by Scottish botanist Robert Brown in 1810, with the name Davallia dubia, [2] it gained its current name with the new genus Calochlaena described in 1988. [3] The genus name is derived from the Ancient Greek kalos "beautiful" and chlaina "cloak", and refers to the soft hairs on the species, [4] while the species name dubia is the Latin dubious. It was known for many years as Culcita dubia, [5] before the genus Calochlaena was split out in 1988. [6]
The true brackens belong to the family Dennstaedtiaceae. [7]
The fronds arise from the thick brown haired rhizomes and are anywhere from 0.4 to 1.5 m in height. [1] The foliage is a more yellow green colour, in contrast to the darker shiny green of bracken ( Pteridium esculentum ). The stipe changes from dark brown, through reddish- to yellow brown, and is covered with soft brown hairs. The fronds are triangular overall and tripinnate-pinnatifid in shape. The sori occur near the margin. [8]
Calochlaena dubia is found as an understory plant in open forests and rainforests in eastern Australia, from Queensland, through New South Wales and Victoria into Tasmania. It can form large banks or swathes. [8]
Well suited to the garden, Calochlaena dubia is an easy plant to grow. [9] In fact, it must be kept in check by cutting the rhizomes and given plenty of room. It does well on clay soils. [5]
Bracken (Pteridium) is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells. Brackens are noted for their large, highly divided leaves. They are found on all continents except Antarctica and in all environments except deserts, though their typical habitat is moorland. The genus probably has the widest distribution of any fern in the world.
Pteridium aquilinum, also known as eagle fern, is a species of fern occurring in temperate and subtropical regions in both hemispheres. Originally native to Eurasia and North America, the extreme lightness of its spores has led to it achieving a cosmopolitan distribution.
Atherosperma moschatum, the southern sassafras or blackheart sassafras, is an evergreen tree native to the cool temperate rainforests of Tasmania, Victoria, and New South Wales in Australia. It is common in the rainforests of Tasmania and Victoria, but more scattered and rare in the higher altitudes of eastern New South Wales. The northernmost area is at Mount Grundy, west of Port Macquarie.
Oplismenus is a small genus of annual or perennial grasses, commonly known as basketgrass, found throughout the tropics, subtropics, and in some cases, temperate regions of the Americas, Africa, Asia, and Australia. The systematics of the genus are unclear, with over 100 described species, only 7 species are officially recognized as of 2016.
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.
Acidonia microcarpa is a species of shrub in the plant family Proteaceae. It is the only species in the genus Acidonia. It is endemic to the south coast of the Southwest Botanic Province of Western Australia.
Asplenium australasicum, the bird's nest fern or crow's nest fern, is an epiphytic Australasian species of fern in the family Aspleniaceae.
Doodia aspera, commonly known as prickly rasp fern, is a widespread and common plant, growing in eastern Australia. Often seen in rainforest margins or eucalyptus forest in Victoria, New South Wales and Queensland, it is a terrestrial fern with reddish new growth.
Astroloma pinifolium, commonly known as pine heath, is small prostrate shrub or groundcover in the family Ericaceae endemic to eastern Australia.
Gahnia aspera known as the rough saw-sedge or round sawsedge is a tussock forming perennial plant, often seen in moist situations. The long strap like leaves grow to 80 cm long.
Pteridium esculentum, commonly known as bracken fern, Austral bracken or simply bracken, is a species of the bracken genus native to a number of countries in the Southern Hemisphere. Esculentum means edible. First described as Pteris esculenta by German botanist Georg Forster in 1786, it gained its current binomial name in 1908. The Eora people of the Sydney region knew it as gurgi.
Pteris tremula, commonly known as Australian brake, tender brake, tender brakefern, shaking brake is a fern species of the family Pteridaceae native to sheltered areas and forests in eastern Australia and New Zealand. It has pale green, lacy fronds of up to 2 meters in length, with an erect, tufted rhizome that is covered with narrow brown scales. It is fast-growing and easy to grow in cultivation, but can become weedy.
Calochlaena is a genus of ferns within the family Dicksoniaceae. Although these ground ferns resemble bracken, they are only distantly related. Five species are known from Melanesia, Polynesia and eastern Australia. Calochlaena dubia, is a common fern of the east coast of Australia. The name is derived from the Ancient Greek kalos "beautiful" and chlaina "cloak", and refers to the soft hairs on the species.
Gleichenia dicarpa, commonly known as pouched coral fern or tangle fern, is a small fern of the family Gleicheniaceae found in eastern Australia, New Caledonia and New Zealand. It forms tangled thickets in wet places such as swamps and riverbanks.
Angiopteris evecta, commonly known as the king fern, giant fern, elephant fern, oriental vessel fern, Madagascar tree fern, or mule's Foot fern, is a very large rainforest fern in the family Marattiaceae native to most parts of Southeast Asia and Oceania. It has a history dating back about 300 million years, and is believed to have the longest fronds of any fern in the world.
Adiantum hispidulum, commonly known as rough maidenhair fern or five-fingered jack, is a small fern in the family Pteridaceae of widespread distribution. It is found in Africa, Australia, Polynesia, Malesia, New Zealand and other Pacific Islands. Its fronds rise in clumps from rhizomes among rocks or in the soil in sheltered areas.
Adiantum aethiopicum, also known as the common maidenhair fern, is a small fern of widespread distribution, occurring in Africa, Australia, Norfolk Island and New Zealand.
Adiantum formosum, known as the giant maidenhair or black stem maidenhair is a fern found in Australia and New Zealand. It was one of the many species authored by Scottish botanist Robert Brown, appearing in his 1810 work Prodromus Florae Novae Hollandiae et Insulae Van Diemen. Its species name is the Latin adjective formosus "handsome" or "beautiful".
Decaspermum humile, commonly known as the silky myrtle, is a tree from Australia and Asia. It can be used as bush food, as indicated by the alternate common name of currant myrtle. The tree features an attractive dark glossy crown. The new pink leaves with silvery hairs are particularly appealing.
Gmelina fasciculiflora, known as the northern white beech is a species of trees endemic to the Queensland tropical rain forests, Australia, of the mint (Lamiaceae) plant family. It is one of four recognised species of the genus Gmelina found in Australia.
