Marsilea Schelpeana
''Marsilea'' is a genus of approximately 65 species of aquatic ferns of the family Marsileaceae. The name honours Italian naturalist Luigi Ferdinando Marsili (1656–1730). These small plants are of unusual appearance and do not resemble common ferns. Common names include water clover and four-leaf clover because of the long-stalked leaves have four clover-like lobes and are either present above water or submerged. The sporocarps of some Australian species are very drought-resistant, surviving up to 100 years in dry conditions. On wetting, the gelatinous interior of the sporocarp swells, splitting it and releasing a worm-like mass that carries sori, eventually leading to germination of spores and fertilization. Uses As food Sporocarps of some Australian species such as '' Marsilea drummondii'' are edible and have been eaten by Aborigines and early white settlers, who knew it under the name ngardu or nardoo. Parts of ''Marsilea drummondii'' contain an enzyme which dest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marsilea Villosa
''Marsilea villosa'', the ihiihi (Hawaiian language, Hawaiian) or villous waterclover (English language, English), is a species of fern that is Endemism, endemic to the islands of Oahu, Oahu, Molokai, Molokai and Niihau, Niihau in Hawaii. It is found exclusively in areas that experience periodic flooding and become Vernal pool, ephemeral pools within low elevation Hawaiian tropical dry forests, dry forests and Hawaiian tropical low shrublands, shrublands. Standing water allows the Sporocarp (ferns), sporocarp to open and release spores. It also enables the resulting sperm to swim toward and Fertilization, fertilize female Ovum, ova. For new plants to become established, the waters must subside. Sporocarps only form once the soil has dried to a certain level. Like other species in its genus, the leaves of ''M. villosa'' resemble those of a four-leaf clover. Conservation Fewer than 2,000 individual plants exist in four remaining populations. The plant was federally listed as an Enda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Hugh Garfit Alston
Arthur Hugh Garfit Alston (born in West Ashby on 4 September 1902; died in Barcelona on 17 March 1958) was an English botanist.

Merritt Lyndon Fernald
Merritt Lyndon Fernald (October 5, 1873 – September 22, 1950) was an American botanist. He was a respected scholar of the taxonomy and phytogeography of the vascular plant flora of temperate eastern North America. During his career, Fernald published more than 850 scientific papers and wrote and edited the seventh and eighth editions of ''Gray's Manual of Botany''. Fernald coauthored the book ''Edible Wild Plants of Eastern North America'' in 1919–1920 with Alfred Kinsey, which was published in 1943. Biography Fernald was born in Orono, Maine. His parents were Mary Lovejoy Heywood and Merritt Caldwell Fernald, a college professor at the University of Maine. Fernald attended Orono High School, during which time he decided that he wanted to become a botanist. He collected plants around Orono and published two botanical papers while still attending high school. Fernald attended Maine State College for a year, but began working as an assistant at the Gray Herbarium at Harvard Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marsilea Minuta
''Marsilea minuta'', or dwarf waterclover is a species of aquatic fern in the family Marsileaceae. It is not to be confused with ''Marsilea minuta'' E.Fourn. 1880, which is a synonym for '' Marsilea vestita''. Other common names include gelid waterklawer, small water clover, airy pepperwort, and pepperwort, though the lattermost also applies to plants in the genus Lepidium. In French it is called ' (literally "four-leafed marsilea") and ' (literally "little Marsilea"), the latter appearing to be a calque with the Latin botanical name. In Chinese it is (), literally "southern field word grass," referencing the similarity of the leaflet shape to the Chinese character for "field." The Koch Rajbongshi people and Garo people call it '. It is called '' ('shushni shak') in Bengali. In parts of India it can be called ' In Indonesian it is ' (literally "clover"), but this name also applies to '' Marsilea crenata''.

George Engelmann
George Engelmann, also known as Georg Engelmann, (2 February 1809 – 4 February 1884) was a German-American botanist. He was instrumental in describing the flora of the west of North America, then very poorly known to Europeans; he was particularly active in the Rocky Mountains and northern Mexico, one of his constant companions being another German-American, the botanical illustrator Paulus Roetter. Biography Origins George Engelmann was born in Frankfurt am Main, Germany, the oldest of thirteen children, nine of whom reached maturity. His father, Julius Bernhardt Engelmann, was a member of a family from which for several successive generations were chosen ministers for the Reformed Church at Bacharach-on-the-Rhine. Julius was a graduate of the University of Halle, and was also educated for the ministry, but he devoted his life to education. He established a school for young women in Frankfurt, which was rare at the time. George Engelmann's mother, Julie Antoinette, was the ...

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...
