Heterotheca Camporum
''Heterotheca camporum'', known by the common name lemonyellow false goldenaster, is a North American species of flowering plant in the family Asteraceae. It is found only in the central United States, primarily the Ozarks, the Cumberland Plateau, and the middle Mississippi Valley. There are reports of additional populations in the Northeast, the Southeast, and in the Great Lakes region, but these appear to be waifs or naturalizations. ''Heterotheca camporum'' is a perennial herb growing 150 centimeters (5 feet) in height, spreading by means of underground rhizomes. There can be as many as 100 stems from one clone. Each stem can produce 1-24 flower heads A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, compos ... in flat-topped arrays Each head contains 16–38 ray florets surrounding 23– ...

Edward Lee Greene
Edward Lee Greene (August 20, 1843–November 10, 1915) was an American botanist known for his numerous publications including the two-part ''Landmarks of Botanical History'' and the describing of over 4,400 species of plants in the American West. Early life Edward Lee Greene was born on August 20, 1843 in Hopkinton, Rhode Island. In 1859 Greene moved to Wisconsin and began studying at Albion Academy, a very reputable institution with a religious emphasis. There Greene met Thure Kumlien, a Swedish Naturalist with an interest in botany. Greene accompanied Kumlein on field trips, further developing Greene's interest in botany. In August 1862, Greene joined his father and brothers in joining the 13th Wisconsin Volunteer Infantry Regiment of the Union Army. Though he never rose above the rank of private in his three years of service, Greene was able to advance his botanical studies, collecting specimens as he marched through Tennessee, Kentucky and Alabama.

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Ozarks
The Ozarks, also known as the Ozark Mountains, Ozark Highlands or Ozark Plateau, is a physiographic region in the U.S. states of Missouri, Arkansas, Oklahoma and the extreme southeastern corner of Kansas. The Ozarks cover a significant portion of northern Arkansas and most of the southern half of Missouri, extending from Interstate 40 in central Arkansas to Interstate 70 in central Missouri. There are two mountain ranges in the Ozarks: the Boston Mountains of Arkansas and the St. Francois Mountains of Missouri. Buffalo Lookout, the highest point in the Ozarks, is located in the Boston Mountains. Geologically, the area is a broad dome with the exposed core in the ancient St. Francois Mountains. The Ozarks cover nearly , making it the most extensive highland region between the Appalachians and Rockies. Together with the Ouachita Mountains, the area is known as the U.S. Interior Highlands. The Salem Plateau, named after Salem, Missouri, makes up the largest geologic area o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cumberland Plateau
The Cumberland Plateau is the southern part of the Appalachian Plateau in the Appalachian Mountains of the United States. It includes much of eastern Kentucky and Tennessee, and portions of northern Alabama and northwest Georgia. The terms "Allegheny Plateau" and the "Cumberland Plateau" both refer to the dissected plateau lands lying west of the main Appalachian Mountains. The terms stem from historical usage rather than geological difference, so there is no strict dividing line between the two. Two major rivers share the names of the plateaus, with the Allegheny River rising in the Allegheny Plateau and the Cumberland River rising in the Cumberland Plateau in Harlan County, Kentucky. Geography The Cumberland Plateau is a deeply dissected plateau, with topographic relief commonly of about , and frequent sandstone outcroppings and bluffs. At Kentucky's Pottsville Escarpment, which is the transition from the Cumberland Plateau to the Bluegrass in the north and the Pennyril ...

Northeastern United States
The Northeastern United States, also referred to as the Northeast, the East Coast, or the American Northeast, is a geographic region of the United States. It is located on the Atlantic coast of North America, with Canada to its north, the Southern United States to its south, and the Midwestern United States to its west. The Northeast is one of the four regions defined by the U.S. Census Bureau for the collection and analysis of statistics. The region is usually defined as including nine U.S. states: Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont. The U.S. Census Bureau–defined region of the Northeastern United States has a total area of with of that being land mass, making it the smallest region of the United States by both land mass and total area. The Northeastern region is the nation's most economically developed, densely populated, and culturally diverse region. Of the nation's four census regions, the No ...

Great Lakes Region
The Great Lakes region of North America is a binational Canadian–American region that includes portions of the eight U.S. states of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania and Wisconsin along with the Canadian province of Ontario. Quebec is at times included as part of the region because, although it is not in a Great Lake watershed, it encompasses most of the St. Lawrence River watershed, part of a continuous hydrologic system that includes the Great Lakes. The region centers on the Great Lakes and forms a distinctive historical, economic, and cultural identity. A portion of the region also encompasses the Great Lakes Megalopolis. Participating state and provincial governments are represented in the Conference of Great Lakes and St. Lawrence Governors and Premiers, which also serves as the Secretariat to the Great Lakes St. Lawrence Compact and the Great Lakes–Saint Lawrence River Basin Sustainable Water Resources Agreement.

Head (botany)
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorp ...

Heterotheca
''Heterotheca'', (common names goldenasters, camphorweed, or telegraph weed) are North American plants in the family Asteraceae. Etymology ''Heterotheca'' comes from Ancient Greek "other, different" and "case, chest", and refers to the fact that, in some species in the genus, the cypselae (achenes containing seed) of the disk and ray florets have different shapes. Description, biology These are annual and perennial herbs bearing daisy-like flower heads with yellow disc florets and usually yellow ray florets, associated with mesic to xeric habitats across North America. Several species now included in ''Heterotheca'' were previously classified in the genus '' Chrysopsis'' ''Heterotheca'' species are often used as food plants by the larvae of some Lepidoptera species including '' Schinia lynx'', ''Schinia nubila'' and '' Schinia saturata'' (all of which have been recorded on ''Heterotheca subaxillaris'').

Endemic Flora Of The United States
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
