Salviniales
The order Salviniales (formerly known as the Hydropteridales and including the former Marsileales) is an order of ferns in the class Polypodiopsida. Description Salviniales are all aquatic and differ from all other ferns in being heterosporous, meaning that they produce two different types of spores (megaspores and microspores) that develop into two different types of gametophytes (female and male gametophytes, respectively), and in that their gametophytes are endosporic, meaning that they never grow outside the spore wall and cannot become larger than the spores that produced them. The megasporangia each produce a single megaspore. In being heterosporus with endosporic gametophytes they are more similar to seed plants than to other ferns. The fertile and sterile leaves are dimorphic, taking on a different shape, and leaves bear anastomosing veins. Aerenchyma is frequently present in roots, shoots, and petioles (leaf stalks). The ferns of this order vary radically in form and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austroblechnum Lanceolatum
''Austroblechnum lanceolatum'', synonym ''Blechnum chambersii'', is a species of fern within the family Blechnaceae, found in Australia, New Zealand, Samoa and Fiji.

Azolla Filiculoides
''Azolla filiculoides'' (water fern) is a species of ''Azolla'', native to warm temperate and tropical regions of the Americas which was introduced to Europe, North and sub-Saharan Africa, China, Japan, New Zealand, Australia, the Caribbean and Hawaii. It is a floating aquatic fern, with very fast growth, capable of spreading over lake surfaces to give complete coverage of the water in only a few months. Each individual plant is 1–2 cm across, green tinged pink, orange or red at the edges, branching freely, and breaking into smaller sections as it grows. It is not tolerant of cold temperatures and, in temperate regions it largely dies back in winter, surviving by means of submerged buds. It harbors the diazotrophic organism, ''Nostoc azollae'', in specialized leaf pockets. This ancient symbiosis allows ''N. azollae'' to fix nitrogen from the air and contribute to the fern's metabolism. Fossil records from as recent as the last interglacials are known from several location ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolbitis Heudelotii
''Bolbitis heudelotii'', also known as the African water fern, creeping fern, and Congo fern, is native to subtropical and tropical Africa, from Ethiopia west to Senegal; and down to northern South Africa. Description ''Bolbitis heudelotii'', named for the botanical explorer of West Africa Jean-Pierre Heudelot (1802–1837), is an aquatic polypody fern growing submerged in rivers and streams, attached to rocks or wood by the threadlike rootlets extending from its rhizomes. It has dark green, pinnate leaves 15–40 cm long and 15–25 cm broad. It grows submerged. The water in its native habitat is fast-moving over sandy or rocky bottoms, very clean, not very hard and slightly acidic. The roots cling to rocks and the sandy beds. Cultivation In the aquarium, ''B. heudelotii'' requires water temperatures of 20–28 °C and moderately acidic ('soft') to neutral water with a pH range of 5.0–7.0, but tolerates a wide range of light levels. It does best in flowing wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cranfillia Fluviatilis
''Cranfillia fluviatilis'', synonym ''Blechnum fluviatile'', is a fern known in the Māori language as kiwikiwi. A herbaceous plant, ''C. fluviatilis'' is a "hard fern" of the genus '' Cranfillia'' in the family Blechnaceae. It was identified by Patrick Brownsey in 1979. Other common names are star fern, creek fern, kawakawa and kiwakiwa. Morphology Ladderlike fronds of ''C. fluviatilis'' measure up to long. Growing in a distinctive ground-hugging rosette shape, its fertile fronds – dark brown and spiky – stand upright from the centre, while the drooping sterile fronds with their nearly round leaflets, form the rosette. As the parent plant ages it develops a short trunk central to a surrounding colony. Range and ecology The hardy ''C. fluviatilis'' requires moist, shaded conditions for optimal growth. A small ground fern, the species is native to New Zealand and southeast Australia, a syntype common throughout the country in damp, shady areas in acidic, moist and ...

Histiopteris Incisa
''Histiopteris incisa'', the bat's wing fern, water fern or fern mata, is a common plant found in Australia, New Zealand and other islands in the south Pacific region. Usually found in moist areas, where it may form large colonies. The lowermost lobes of each pinnae have a bat wing like appearance, giving the fern its common name. Description ''Histiopteris incisa'' is a medium-sized fern, usually producing fronds of approximately 60–200 cm in length. Fronds are widely spaced, distinct, and slightly dimorphic with fertile lobes slightly narrower than the infertile lobes. Fertile lobes have the sori continuous, linear and exindusiate (without an indusium A sorus (pl. sori) is a cluster of sporangia (structures producing and containing spores) in ferns and fungi.

Lomaria Nuda
''Lomaria nuda'', commonly known as the fishbone waterfern, is a fern that grows up to a metre tall, and is abundant in rainforest and eucalyptus forests in eastern Australia. The species is placed in the genus ''Lomaria'' in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), but is often retained in genus ''Blechnum'' as ''Blechnum nudum''. Habit The mature fishbone waterfern typically has simple, pinnate fronds of length 40–60 cm. Fronds have a short, thick stipe that is sometimes covered in small hairs. The class of blechnum ferns are typified by having distinct fertile and sterile fronds. Fertile fronds are easily distinguishable from sterile fronds in the fishbone waterfern. Overall, sterile fronds tend to be more delicate in appearance, with a thinner longer stipe. Fertile fronds are simply pinnate, like the sterile variety, but can grow to be much longer than sterile fronds in the fishbone fern. Pinna are thin, with a rounder profile than the flat p ...

Oceaniopteris Cartilaginea
''Oceaniopteris cartilaginea'', synonym ''Blechnum cartilagineum'', is known as the gristle fern or soft water fern. It is a resilient and abundant fern growing in eastern Australia, seen in rainforest and eucalyptus ''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as euca ... forest. The new growth is often pink or reddish in colour. It is very tolerant of dry conditions once established in a shady area.

Osmunda Regalis
''Osmunda regalis'', or royal fern, is a species of deciduous fern, native to Europe, Africa and Asia, growing in woodland bogs and on the banks of streams. The species is sometimes known as flowering fern due to the appearance of its fertile fronds. Names The name ''Osmunda'' possibly derives from ''Osmunder'', a Saxon name for the god Thor. The name "royal fern" derives from its being one of the largest and most imposing European ferns. The name has been qualified as "old world royal fern" in some American literature to distinguish it from the closely related American royal fern, '' O. spectabilis''. However this terminology is not found in British literature. Description ''Osmunda regalis'' produces separate fertile and sterile fronds. The sterile fronds are spreading, tall and broad, bipinnate, with 7-9 pairs of pinnae up to long, each pinna with 7-13 pairs of pinnules 2.5-6.5 cm long and 1–2 cm broad. The fertile fronds are erect and shorter, 20–50 cm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parablechnum Wattsii
''Parablechnum wattsii'', synonym ''Blechnum wattsii'', is a common terrestrial fern growing in rainforest and open forest. It is often seen near creeks in much of south eastern Australia, including Victoria, Tasmania (and King Island), South Australia, New South Wales and Queensland. The specific epithet ''wattsii'' honours William Walter Watts (1856-1920). Watts was considered an authority on mosses and ferns and has more than 30 species named for him. Common names by which the species may be called are hard water fern - from its stiff leathery fronds, leech fern - as forest workers often encounter leaches while working in clusters of these ferns, hard hill fern - from the fern's habit and habitat, and red cabbage fern - from the bronze-pink colour of the young fronds resembling cooked red cabbage. Habit The mature ''Parablechnum wattsii'' can grow from 30 cm to 125 cm tall, with large erect fronds. The fern can spread horizontally using scaled rhizomes, which have ...
