Agoseris
''Agoseris'' is a small genus of annual or perennial herbs in the family Asteraceae described as a genus in 1817. ''Agoseris'' is native to North America, South America and the Falkland Islands. In general appearance, ''Agoseris'' is reminiscent of dandelions and are sometimes called mountain dandelion or false dandelion. Like dandelions the plants are (mostly) stemless, the leaves forming a basal rosette, contain milky sap, produce several unbranched, stem-like flower stalks ( peduncles), each flower stalk bearing a single, erect, liguliferous flower head that contains several florets, and the flower head maturing into a ball-like seed head of beaked achenes, each achene with a pappus of numerous, white bristles.

Agoseris Aurantiaca
''Agoseris aurantiaca'' is a species of plant in the family Asteraceae, commonly called orange agoseris or mountain dandelion. It is widespread in western North America. Description ''Agoseris aurantiaca'' is a perennial herb or subshrub growing to in height. It produces a basal rosette of leaves, which are long. There is no stem, but it does produce several stem-like peduncles. Between June and August, each peduncle bears a single flower head in width, surrounded by glabrous to hairy phyllaries. The head is ligulate, containing several ray florets but no disc florets. The florets are most commonly orange but are occasionally yellow, pink, red, or purple. "Aurantiaca" means "orange-red".Great Basin Wildflowers, Laird R. Blackwell, 2006, Morris Book Publishing LLC., The flower head matures into a ball-like head of beaked achenes, each with a terminal pappus of numerous, white bristles.

Agoseris Monticola
''Agoseris monticola'' is a North American species of flowering plants in the family Asteraceae known by the common name Sierra Nevada agoseris or Sierra Nevada mountain dandelion. It grows in the mountains of the western United States, primarily the Cascade Range and Sierra Nevada, but also on other mountains in Nevada and Idaho.

There is a single flower head with many yellow ray florets but no disc floret The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales.

Agoseris Apargioides
''Agoseris apargioides'' is a species in the family Asteraceae, is commonly called seaside agoseris or seaside false-dandelion. It is native to the Pacific coast of the United States from Washington to central California, where it grows primarily on coastal dunes. ''Agoseris apargioides'' is a low-growing, perennial herb with milky or orange sap, that may be stemless or with long, rhizome-like stems that are buried by drifting sand. The leaves form low rosettes on the ground. They are slender to broad, up to 15 centimeters long, and usually with 3-5 pairs of lobes along the margins (these sometimes lacking). The peduncle of the inflorescence can be as tall as 45 centimeters but is usually much shorter. The flower head is up to 2 centimeters wide, surrounded by glabrous to hairy phyllaries, and contains yellow ray florets (the outer ones often have a purple strip on the lower surface) but no disc florets. The fruit is an achene between 5-12 millimeters long; the lower part of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Gaertner
Joseph Gaertner (12 March 1732 – 14 July 1791) was a German botanist, best known for his work on seeds, ''De Fructibus et Seminibus Plantarum'' (1788-1792). Biography He was born in Calw, and studied in Göttingen under Albrecht von Haller. He was primarily a naturalist, but also worked at physics and zoology. He travelled extensively to visit other naturalists. He was professor of anatomy in Tübingen in 1760, and was appointed professor of botany at St Petersburg in 1768, but returned to Calw in 1770. Gaertner made back cross to convert one species into another. Back cross increases nuclear gene frequency His observations were: 1. Dominance of traits 2. Equal contribution of male and female to the progeny 3. No variation in F1 (first generation of descendants) 4. Large variation in F2 (second generation of descendants) including parental and intermediate types 5. Some of F2 plants had entirely new traits but he was unable to give possible explanation for observ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endl
Newline (frequently called line ending, end of line (EOL), next line (NEL) or line break) is a control character or sequence of control characters in character encoding specifications such as ASCII, EBCDIC, Unicode, etc. This character, or a sequence of characters, is used to signify the end of a line (text file), line of text and the start of a new one. History In the mid-1800s, long before the advent of teleprinters and teletype machines, Morse code operators or telegraphists invented and used Prosigns for Morse code, Morse code prosigns to encode white space text formatting in formal written text messages. In particular the International Morse code, Morse prosign (mnemonic reak ext) represented by the concatenation of literal textual Morse codes "B" and "T" characters sent without the normal inter-character spacing is used in Morse code to encode and indicate a ''new line'' or ''new section'' in a formal text message. Later, in the age of modern teleprinters, standardiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...
