Ophioglossaceae
Ophioglossaceae, from Ancient Greek ὄφις (''óphis''), meaning "snake", and γλῶσσα (''glôssa''), meaning "tongue", also known as the adder's-tongue family, is a small family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is the only family in the order Ophioglossales, which together with the Psilotales is placed in the subclass Ophioglossidae. The Ophioglossidae are one of the groups traditionally known as eusporangiate ferns. Members of the family differ from other ferns in a number of ways. Many have only a single fleshy leaf at a time. Their gametophytes are subterranean and rely on fungi for energy. Description Members of Ophioglossaceae are usually terrestrial (excepting a few epiphytic species of '' Ophioglossum'') and occur in both temperate and tropical areas. They differ from the other ferns in several respects: * Many species only send up one frond or leaf-blade per year, producing only a single leaf at a time. The leaves ...

Helminthostachys Zeylanica
''Helminthostachys zeylanica'' is a terrestrial, herbaceous fern of southeastern Asia and Australia, commonly known as kamraj and tunjuk-langit. The species is like the other members of its family, it has clusters of sporangia on stems of fertile, spike-like fronds. The rhizome of this annual plant is short, creeping, underground, and stout. They can bear either a solitary frond or several fronds. Leaves are lanceolate with the margins entire or irregularly serrate. The frond spike arises from the base of the leaves with its own stipe. Below the spike is a sterile leafy segment (the trophophore). Both it and the sporophore arise from a common petiole. Uses The roots of this plant are a popular medicine in China, where they are known as "Di wu gong". The roots are harvested during the wet season in July–August. Only wild plants are harvested. In Malaysia, the leaves are dried and smoked to treat bleeding nose. The plant is eaten as a vegetable and used medicinally for impotenc ...

Georg Friedrich Kaulfuss
Georg Friedrich Kaulfuss (8 April 1786 – 9 December 1830) was a professor at Halle. He described the pteridophytes collected by Adelbert von Chamisso, and he named the fern ''Cibotium chamissoi'' after him. The genus '' Kaulfussia'' is named for Kaulfuss. In 1816, he obtained his doctorate from the University of Halle, where in 1823, he became a full professor of botany. Plants Named by Kaulfuss More than 200 plant names were published by Kaulfuss. Tropicos.org. Missouri Botanical Garden. 01 Feb 2012 These include the genera: * *'' Cochlidium'' * *'' Balantium'' * Plant families named by Kaulfuss include: * |
Fern
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaf, leaves called megaphylls that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled Fiddlehead fern, fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae (plant), Polypodiidae) and eusporangiate ferns, the latter group including horsetails, Psilotaceae, whisk ferns, marattioid ferns, and ophioglossoid ferns. The fern crown group, consisting of the leptosporangiates and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...
