Pentarhizidium Orientale
''Pentarhizidium orientalis'', the Oriental ostrich fern, is a fern native to China, Japan, and the Himalayas. It grows to about 0.6 m (2 ft) in height by 0.6 m (2 ft) wide. It was formerly included in the genus ''Matteuccia'', but phylogenetic studies mandated that it and '' Pentarhizidium intermedium'' be moved to a new genus.

William Jackson Hooker
Sir William Jackson Hooker (6 July 178512 August 1865) was an English botany, botanist and botanical illustrator, who became the first director of Kew Gardens, Kew when in 1841 it was recommended to be placed under state ownership as a botanic garden. At Kew he founded the Herbarium and enlarged the gardens and arboretum. Hooker was born and educated in Norwich. An inheritance gave him the means to travel and to devote himself to the study of natural history, particularly botany. He published his account of an expedition to Iceland in 1809, even though his notes and specimens were destroyed during his voyage home. He married Maria, the eldest daughter of the Norfolk banker Dawson Turner, in 1815, afterwards living in Halesworth for 11 years, where he established a herbarium that became renowned by botanists at the time. He held the post of Regius Professor of Botany at Glasgow University, where he worked with the botanist and lithographer Thomas Hopkirk and enjoyed the su ...

Bunzō Hayata
was a Japanese botanist noted for his taxonomic work in Japan and Formosa, present day Taiwan. Early life Hayata was born to a devout Buddhist family in Kamo, Niigata on December 2, 1874. When he was 16, Hayata became interested in botany, and he joined the Botanical Society of Tokyo in 1892. His schooling was delayed by a series of family tragedies, and he graduated middle school at the age of 23. He then attended high school and began to collect botanical samples.Ohashi, Hiroyoshi (2009). Bunzo Hayata and His Contributions to the Flora of Taiwan' Taiwania, 54(1): 1-27 Hayata enrolled in the botany program at the Imperial University of Tokyo in 1900. He graduated in 1903, and entered the graduate program under Jinzō Matsumura. He was appointed assistant at the Koishikawa Botanical Gardens in 1904. In 1907, he completed his Doctor of Sciences degree. Career In 1908, Hayata was promoted to lecturer in the Department of Botany at the Imperial University of Tokyo. Hayata u ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes 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 leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled 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) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid fe ...

Japan
Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north toward the East China Sea, Philippine Sea, and Taiwan in the south. Japan is a part of the Ring of Fire, and spans an archipelago of 6852 islands covering ; the five main islands are Hokkaido, Honshu (the "mainland"), Shikoku, Kyushu, and Okinawa. Tokyo is the nation's capital and largest city, followed by Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, Kobe, and Kyoto. Japan is the eleventh most populous country in the world, as well as one of the most densely populated and urbanized. About three-fourths of the country's terrain is mountainous, concentrating its population of 123.2 million on narrow coastal plains.

Himalayas
The Himalayas, or Himalaya (; ; ), is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the very highest, Mount Everest. Over 100 peaks exceeding in elevation lie in the Himalayas. By contrast, the highest peak outside Asia ( Aconcagua, in the Andes) is tall. The Himalayas abut or cross five countries: Bhutan, India, Nepal, China, and Pakistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China. The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo– Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas.

Matteuccia
''Matteuccia'' is a genus of ferns with one species: ''Matteuccia struthiopteris'' (common names ostrich fern, fiddlehead fern, or shuttlecock fern). The species epithet ''struthiopteris'' comes from Ancient Greek words () "ostrich" and () "fern". Description The fronds are dimorphic, with the deciduous green sterile fronds being almost vertical, tall and broad, long-tapering to the base but short-tapering to the tip, so that they resemble ostrich plumes, hence the name. The fertile fronds are shorter, long, brown when ripe, with highly modified and constricted leaf tissue curled over the sporangia; they develop in autumn, persist erect over the winter and release the spores in early spring. Along with '' Dryopteris goldieana'', it is one of the largest species of fern in eastern North America. Classification ''Matteuccia struthiopteris'' is the only species in the genus ''Matteuccia''. Some sources include two Asian species, ''M. orientalis'' and ''M. intermedia'', but mole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentarhizidium Intermedium
''Pentarhizidium'' is a genus of two Asian fern species. These species have formerly been included in ''Matteuccia'' or ''Onoclea ''Onoclea'' is a genus of plants in the family Onocleaceae, native to moist habitats in eastern Asia and eastern North America. They are deciduous ferns with sterile fronds arising from creeping rhizomes in spring, dying down at first frost. Fert ...''. Recent genetic analysis has determined that these two species form a discrete clade that is basal to the rest of this fern group, and so have been located in their own genus. ''P. orientale'' is sometimes grown as a garden plant. Species References Polypodiales Ferns of Asia Fern genera {{Polypodiales-stub ...

American Fern Society
The American Fern Society was founded in 1893. Today, it has more than 1,000 members around the world, with various local chapters. Among its deceased members, perhaps the most famous is Oliver Sacks, who became a member in 1993. Willard N. Clute was the founder of the society, originally establishing it as the Linnaean Fern Chapter of the Agassiz Association. The chapter had two comprehensive group meetings, one in 1898 and another in 1900. The chapter consisted of small regional divisions and circulated reports by mail from member to member. In 1905 the members of the Linnean Fern Chapter separated from the Agassiz Association and formed the American Fern Society. The society has published the ''American Fern Journal'', a technical botanical journal, since 1910. Before that, it published ''The Fern Bulletin'' (originally "The Linnaean Fern Bulletin") from 1892 to 1912. It has also published ''The Fiddlehead Forum'', a member newsletter, since 1974. Since 1979, it has published ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
