Gymnolomia Porteri
''Helianthus porteri'' is a species of sunflower known by the common names Porter's sunflower, Stone Mountain daisy and Confederate daisy. The term "daisy" is a imprecise because the species is a sunflower (''Helianthus'') rather than a daisy (''Bellis'' and related genera). Likewise, although the plant grows on Stone Mountain, GA, its range extends well beyond. The connection to the Confederacy is through Stone Mountain which contains a confederate monument, although the connection is tenuous as the species was named before the Civil War in 1849 by Harvard botanist Asa Gray in honor of Thomas Conrad Porter, a Pennsylvanian minister and botanist who collected the plant in Georgia. Gray initially named the plant ''Rudbeckia porteri'', changed to ''Helianthus'' in 1998 by John F. Pruski. The common name Porter's sunflower therefore most closely accords with the history of botanical discovery and naming. The species is native to the southeastern United States, such as Alabama and G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stone Mountain
Stone Mountain is a quartz monzonite dome Inselberg, monadnock and the site of Stone Mountain Park, east of Atlanta, Georgia. Outside the park is the small city of Stone Mountain, Georgia. The park is the most visited tourist site in the state of Georgia. The park is owned by the state of Georgia (U.S. state), Georgia and is currently managed by Herschend Family Entertainment. At its summit, the elevation is AMSL, above sea level and above the surrounding area.

Helianthus
''Helianthus'' () is a genus comprising about 70 species of annual and perennial flowering plants in the daisy family Asteraceae commonly known as sunflowers. Except for three South American species, the species of ''Helianthus'' are native to North America and Central America. The best-known species is the common sunflower (''Helianthus annuus''), whose round flower heads in combination with the ligules look like the Sun. This and other species, notably Jerusalem artichoke (''H. tuberosus''), are cultivated in temperate regions and some tropical regions, as food crops for humans, cattle, and poultry, and as ornamental plants. The species ''H. annuus'' typically grows during the summer and into early fall, with the peak growth season being mid-summer. Several perennial ''Helianthus'' species are grown in gardens, but have a tendency to spread rapidly and can become aggressive. On the other hand, the whorled sunflower, ''Helianthus verticillatus'', was listed as an endanger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Confederate States Of America
The Confederate States of America (CSA), commonly referred to as the Confederate States or the Confederacy was an unrecognized breakaway republic in the Southern United States that existed from February 8, 1861, to May 9, 1865. The Confederacy comprised U.S. states that declared secession and warred against the United States during the American Civil War: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee, and North Carolina. Kentucky and Missouri also declared secession and had full representation in the Confederate Congress, though their territory was largely controlled by Union forces. The Confederacy was formed on February 8, 1861, by seven slave states: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas. All seven were in the Deep South region of the United States, whose economy was heavily dependent upon agriculture—particularly cotton—and a plantation system that relied upon enslaved ...

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ne ...

Thomas Conrad Porter
Thomas Conrad Porter (1822–1901) was an American botanist and theologian known as an expert on the flora of Pennsylvania. Biography Porter was born in Alexandria, Pennsylvania on January 22, 1822. He attended Harrisburg Academy before enrolling in Lafayette College at the age of 14. He graduated in 1840, and returned home to Alexandria and began to collect plants near Tussey Mountain. He went on to attend Princeton Theological Seminary, graduating in 1844. He moved down to Monticello, Georgia for a year as part of a Presbyterian mission. Here he collected at places such as Stone Mountain and Toccoa Falls, and began collaborating with Asa Gray. He discovered '' Gymnolomia porteri'' during his time at Stone Mountain. In 1849, Porter was brought on as a professor of natural sciences at Marshall College. He stayed at the institution until 1866. He then moved to Lafayette College as a professor of botany and zoology, staying until his retirement in 1897. Between 1869 and 1 ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Gneiss
Gneiss ( ) is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. Gneiss forms at higher temperatures and pressures than schist. Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct cleavage. Gneisses are common in the ancient crust of continental shields. Some of the oldest rocks on Earth are gneisses, such as the Acasta Gneiss. Description Orthogneiss from the Czech Republic In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct cleavage. In other words, it is a metamorphic rock composed of mineral grains easily seen with the unaided eye, which form obvious compositional layers, but which has only a weak tendency to fracture ...

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 ...
