Anticlea Elegans
''Anticlea elegans'', commonly known as mountain deathcamas, elegant camas, or glaucous death-camas, is a trillium-relative in the flowering plant family Melanthiaceae. Three distinct subspecies are included ''Anticlea elegans'' subsp. ''elegans'', the type subspecies, plus ''Anticlea elegans'' subsp. ''glauca'' and ''Anticlea elegans'' subsp. ''vaginata''. ''Anticlea elegans'' subsp. ''vaginata'' is likely a result of a vicariance event at the end of the Pleistocene and the populations are genetically drifting apart. Glacial refugia in at least five US states have formerly hosted populations of ''Anticlea elegans'' subsp. ''glauca'', though two are now extirpated. The species is native to most of North America, being absent from California and the Baja California peninsula, the deep southeastern United States, and the far north of Canada. Little is known about the species pollinators, with a small population in Idaho documented to be likely pollinated mostly by flies. Descripti ...

Frederick Traugott Pursh
Frederick Traugott Pursh (or Friedrich Traugott Pursch) (February 4, 1774 – July 11, 1820) was a German people, German–United States, American botanist. Born in Großenhain, in the Electorate of Saxony, under the name Friedrich Traugott Pursh, he was educated at Dresden Botanical Gardens, and emigrated to the United States in 1799. From 1802 to 1805, he worked in Philadelphia as the botanical manager of the extensive gardens of William Hamilton, Esq., "The Woodlands (Philadelphia), The Woodlands." By 1805, he was working for Benjamin Smith Barton on a new Flora (publication), flora of North America, under whom he studied the plants collected on the Lewis and Clark Expedition. His work with Barton allowed him to travel farther afield. In 1805, he traveled south from Maryland to the Carolinas and, in 1806, he traveled north from the mountains of Pennsylvania to New Hampshire. He made both trips principally on foot, with only his dog and a gun, covering over three thousand miles e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lewis And Clark Pass
Lewis and Clark Pass is a mountain pass on the continental divide in Montana, United States, at an elevation of above sea level. The pass lies at the head of the drainages of the west-flowing Blackfoot River and the east-flowing Dearborn River, in the Helena National Forest in Lewis and Clark County. The Continental Divide Trail traverses north and south through the pass. In the early 19th century, the pass was a heavily-used pathway where native peoples crossed over the continental divide. The pass was crossed by Meriwether Lewis with a party of nine men and his dog Seaman on July 7, 1806, on the return leg of the Lewis and Clark Expedition. The pass is named for the expedition's two leaders, Lewis and William Clark. Lewis and Clark Pass is the only roadless mountain pass on the entire Lewis and Clark National Historic Trail. It has gone from being one of the most used continental divide passes prior to the pioneer era to one of the least visited passes today. It can be acce ...

Melanthium
''Melanthium'' is a genus of herbaceous perennial plants native to North America. They are closely related to ''Veratrum'', and in fact are included in that genus by some authors. The distinction between ''Melanthium'' and ''Veratrum'' is based on various morphological traits, but it is not yet clear where the line is best drawn. They contain alkaloids similar to those found in ''Veratrum'' and are thus assumed to be poisonous. Species ThWorld Checklistconsiders ''Melanthium'' as a synonym of ''Veratrum'', and accepts no species as members of ''Melanthium.'' Nor does Plants of the World Onlinebr>Tropicosdoes likewise, adding that proposals have been made to reject the name ''Melanthium'' entirely.Zomlefer, W. B., W. S. Judd & K.N. Gandhi. 2010.

Anticlea
In Greek mythology, Anticlea or Anticlia (; Ancient Greek: ''Ἀντίκλεια'', literally "without fame") was a queen of Ithaca as the wife of King Laërtes. Family Anticlea was the daughter of Autolycus and Amphithea. The divine trickster and messenger of the gods, Hermes, was her paternal grandfather. Anticlea was the mother of Odysseus by Laërtes (though some say by SisyphusHyginus, ''Fabulae'' 201; Plutarch, ''Quaestiones Graecae'' 43; Suida, s.v. Sisyphus''). Ctimene was also her daughter by her husband Laertes. Mythology Early years According to Callimachus, when she was young, Anticlea served the goddess Artemis, and accompanied her in hunting, bearing arrow and quiver. According to some later sources, including a fragment of Aeschylus' lost tragedy ''The Judgment of Arms'', Odysseus was the child of Anticlea by Sisyphus, not Laërtes. In this version of the story, Autolycus, an infamous trickster, stole Sisyphus' cattle. At some point, Sisyphus recogniz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural Bridges National Monument
Natural Bridges National Monument is a U.S. National Monument located about northwest of the Four Corners boundary of southeast Utah, in the western United States, at the junction of White Canyon and Armstrong Canyon, part of the Colorado River drainage. It features the thirteenth largest natural bridge in the world, carved from the white Permian sandstone of the Cedar Mesa Formation that gives White Canyon its name. The three bridges in the park are named ''Kachina'', ''Owachomo'', and ''Sipapu'' (the largest), which are all Hopi names. A natural bridge is formed through erosion by water flowing in the stream bed of the canyon. During periods of flash floods, particularly, the stream undercuts the walls of rock that separate the meanders (or "goosenecks") of the stream until the rock wall within the meander is undercut and the meander is cut off and the new stream bed then flows underneath the bridge. Eventually, as erosion and gravity enlarge the bridge's opening, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Mandan
Fort Mandan was the name of the encampment which the Lewis and Clark Expedition built for wintering over in 1804–1805. The encampment was located on the Missouri River approximately from the site of present-day Washburn, North Dakota, which developed later. The precise location is not known for certain. It is believed now to be under the water of the river. A replica of the fort has been constructed near the original site. Construction and conditions The fort was built of Populus sect. Aegiros, cottonwood lumber cut from the riverbanks. It was triangular in shape, with high walls on all sides, an interior open space between structures, and a gate facing the Missouri River, by which the party would normally travel. Storage rooms provided a safe place to keep supplies. Lewis and Clark shared a room. The men of the Lewis and Clark Expedition, Corps of Discovery started the fort on November 2, 1804. Fort Mandan was completed on November 27, 1804. They wintered there until April 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thomas Nuttall
Thomas Nuttall (5 January 1786 – 10 September 1859) was an English botanist and zoologist who lived and worked in America from 1808 until 1841. Nuttall was born in the village of Long Preston, near Settle in the West Riding of Yorkshire and spent some years as an apprentice printer in England. Soon after going to the United States he met professor Benjamin Smith Barton in Philadelphia. Barton encouraged his strong interest in natural history. Early explorations in the United States In 1810 he travelled to the Great Lakes and in 1811 travelled on the Astor Expedition led by William Price Hunt on behalf of John Jacob Astor up the Missouri River. Nuttall was accompanied by the English botanist John Bradbury, who was collecting plants on behalf of Liverpool botanical gardens. Nuttall and Bradbury left the party at the trading post with the Arikara Indians in South Dakota, and continued farther upriver with Ramsay Crooks. In August they returned to the Arikara post and jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
