Christella dentata is a small fern with widespread distribution in Australia and islands in the south Pacific Ocean. There are many local common names. In New South Wales it grows north from the southern Illawarra region and is known as binung.
Found on the margins of rainforest, by streams or in more open forests with adequate moisture. Sori are circular in shape, [1] with a hairy closed covering.
It was the first species of fern to become naturalised on the Hawaiian Islands, recorded initially in Oahu in 1887 and now found on all major islands there. [2] There it interbreeds with the local species C. cyatheoides , with the resultant hybrid offspring sterile. [3]
Christella dentata is an edible fern, [4] and also a folk remedy for skin diseases. [5] Pharmacological study found that water extract of the fern was as toxic as anticancer drug 5-fluorouracil against human chronic myelogenous leukemia cell line (K562). [6]
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.
Gunnera is the sole genus of herbaceous flowering plants in the family Gunneraceae, which contains 63 species. Some species in this genus, namely those in the subgenus Panke, have extremely large leaves. Species in the genus are variously native to Latin America, Australia, New Zealand, Papuasia, Hawaii, insular Southeast Asia, Africa, and Madagascar. The stalks of some species are edible.
Metrosideros is a genus of approximately 60 trees, shrubs, and vines mostly found in the Pacific region in the family Myrtaceae. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek metra or "heartwood" and sideron or "iron". Perhaps the best-known species are the pōhutukawa, northern and southern rātā of New Zealand, and ʻōhiʻa lehua, from the Hawaiian Islands.
Aegle marmelos, commonly known as, bael, also Bengal quince, golden apple, Japanese bitter orange, stone apple or wood apple, is a species of tree native to the Indian subcontinent and Southeast Asia. It is present in India, Pakistan, Bangladesh, Sri Lanka, and Nepal as a naturalized species. The tree is considered to be sacred by Hindus and Buddhists.
Diplazium esculentum, the vegetable fern, is an edible fern found throughout Asia and Oceania. It is probably the most commonly consumed fern.
Solanum nigrum, the European black nightshade or simply black nightshade or blackberry nightshade, is a species of flowering plant in the family Solanaceae, native to Eurasia and introduced in the Americas, Australasia, and South Africa. Ripe berries and cooked leaves of edible strains are used as food in some locales, and plant parts are used as a traditional medicine. Some other species may also be referred to as "black nightshade".
Typha latifolia, better known as broadleaf cattail, is a perennial herbaceous plant in the genus Typha. It is found as a native plant species in North and South America, Eurasia, and Africa.
Passiflora tarminiana is a species of passionfruit. The yellow fruits are edible and their resemblance to small, straight bananas has given it the name banana passionfruit in some countries. It is native to the uplands of tropical South America and is now cultivated in many countries. In Hawaii and New Zealand it is now considered an invasive species. It was given the name banana passionfruit in New Zealand, where passionfruit are also prevalent. In Hawaii, it is called banana poka. In its Latin American homeland, it is known as curuba, curuba de Castilla, or curuba sabanera blanca (Colombia); taxo, tacso, tagso, tauso (Ecuador); parcha, taxo (Venezuela), tumbo or curuba (Bolivia); tacso, tumbo, tumbo del norte, trompos, tintin or purpur (Peru).
Berberis vulgaris, also known as common barberry, European barberry or simply barberry, is a shrub in the genus Berberis native to the Old World. It produces edible but sharply acidic berries, which people in many countries eat as a tart and refreshing fruit.
Banksia dentata, commonly known as the tropical banksia, is a species of tree in the genus Banksia. It occurs across northern Australia, southern New Guinea and the Aru Islands. Growing as a gnarled tree to 7 m (23 ft) high, it has large green leaves up to 22 cm (8.7 in) long with dentate (toothed) margins. The cylindrical yellow inflorescences, up to 13 cm (5.1 in) high, appear between November and May, attracting various species of honeyeaters, sunbirds, the sugar glider and a variety of insects. Flowers fall off the ageing spikes, which swell and develop follicles containing up to two viable seeds each.
Psilotum nudum, the whisk fern, is a fernlike plant. Like the other species in the order Psilotales, it lacks roots.
Prunella vulgaris, the common self-heal, heal-all, woundwort, heart-of-the-earth, carpenter's herb, brownwort or blue curls, is an herbaceous plant in the mint family Lamiaceae.
The flora of Australia comprises a vast assemblage of plant species estimated to over 21,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (Banksia), Myrtaceae, and Fabaceae.
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.
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.
The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes. More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes provide different ecosystems and climates for plants to grow in, creating a wide variety of different flora spanning over not just China, but different parts of the world.
Christella is a genus of around 70-80 species of ferns in the subfamily Thelypteridoideae of the family Thelypteridaceae in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Christella into a very broadly defined genus Thelypteris. The genus was named after Konrad H. Christ, a Swiss botanist. The distribution of these plants is mostly in the tropics and sub tropical areas. An Australian example is C. dentata.
Cyclosorus interruptus, the Hottentot fern or swamp shield-fern, is a fern in the family Thelypteridaceae. It is native to the tropics and subtropics in many parts of the world. In the New World, it is found from Mexico to Argentina, and in the Antilles. In the Old World, it is found in India, China, Malaysia, Sri Lanka and South Africa. It is also found in Australia, New Zealand, Hawaii and other islands in the Pacific Ocean. The various populations differ with respect to genetic cytotypes, glands, pubescence, and frond size. Its habitat is the vicinity of freshwater swamps and it may reach 1 m in height.
Dipteris conjugata is a species of fern. It has a rhizome, and 2-3 tall stems with mid green or dark green fronds, which have several divisions to toothed lobes. It is grows in clearings, mountain ridges and in forest margins, from tropical and temperate Asia, northern Queensland in Australia and some islands in the Pacific Ocean. It has limited native medicinal uses.
Ophioglossum petiolatum is a species of fern in the family Ophioglossaceae. William Jackson Hooker named this species in 1823.
