Quercus Sinuata Var. Breviloba
''Quercus sinuata'' var. ''breviloba'', commonly called Bigelow oak or Bigelow's oak, is a variety of ''Quercus sinuata'', a species of oak tree that grows in parts of the southern United States and northeastern Mexico. Common names for this taxon are shallow-lobed oak, white shin oak, scaly-bark oak, limestone Durand oak, and shortlobe oak. The less specific common name bastard oak may refer to either of the two varieties of ''Quercus sinuata'', var. ''sinuata'' and var. ''breviloba''. Other common names include scrub oak or shin oak, but these names may refer to a number of other low growing, clump forming oak species, subspecies or varieties. For clear differentiation in common reference, American Forests uses Durand Oak to mean ''Quercus sinuata'' var. ''sinuata'' and Bigelow oak to mean ''Quercus sinuata'' var. ''breviloba'', a shrubby variety of ''Quercus sinuata'' distinguished in part by its habit of forming clonal colonies in parts of its range. Description The Bigelo ...

John Torrey
John Torrey (August 15, 1796 – March 10, 1873) was an American botany, botanist, chemist, and physician. Throughout much of his career, he was a teacher of chemistry, often at multiple universities, while he also pursued botanical work, focusing on the flora of North America. His most renowned works include studies of the New York flora, the Mexican Boundary, the Pacific railroad surveys, and the uncompleted ''Flora of North America''.

Leaves
A leaf (plural, : leaves) is any of the principal appendages of a vascular plant plant stem, stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthesis, photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Walter (botanist)
Thomas Walter (c. 1740 – January 17, 1789) was a British-born American botany, botanist best known for his boo''Flora Caroliniana''(1788), the first flora set in North America to utilize the Linnaean taxonomy, Linnaean system of classification.Rembert (1980) Life and career Walter was born in Hampshire, England, around 1740. Little is known of his family background or early life. He evidently received a good education but no details are available. Sometime before 1769 he arrived in Charleston, South Carolina, where he worked as a merchant. He later acquired a rice plantation on the Santee River where he lived for the rest of his life.Sterling (1997) He became interested in botany and undertook a detailed plant survey within a fifty-mile radius of his home, collecting seeds for his garden and building an extensive herbarium. Based on this effort, Walter completed a manuscript in 1787 containing a summary of all the flowering plant species found in the region. It was the first c ...

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quercus Durandii
''Quercus sinuata'' is a species of oak comprising two distinct varieties, ''Quercus sinuata'' var. ''breviloba'' and ''Quercus sinuata'' var. ''sinuata'', occurring in southeast North America. Description ''Quercus sinuata'' is a deciduous tree up to 20 metres (67 feet) tall. Leaves are narrow, with shallow rounded lobes. It tends to grow in wet habitats, such as on river bluffs, river bottoms, and flatwoods, and generally over basic substrates, such as mafic rocks, shells, or calcareous sediment. There are two varieties, with morphologically intermediate forms sometimes occurring where their ranges overlap: * ''Quercus sinuata'' var. ''breviloba'' (Torr.) C.H.Mull. – Texas, Oklahoma, Mexico * ''Quercus sinuata'' var. ''sinuata'' – Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, Carolinas, Texas Common names Perhaps arising from the classification challenges posed by a lack of morphological consistency among individuals of the species, the common name basta ...

John Milton Bigelow (June 23, 1804 – July 18, 1878) was an American physician and botanist. He had a successful medical practice, and also, a keen interest in botany - especially native plants with medical applications. He participated as a botanist and surgeon on two important expeditions through the American Southwest—the Mexican Boundary Survey and the 35th Parallel Expedition for the Pacific Railroad Surveys.

Sessility (botany)
In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts (such as flowers and leaves) that have no stalk. Plant parts can also be described as subsessile, that is, not completely sessile. A sessile flower is one that lacks a pedicel (flower stalk). A flower that is not sessile is pedicellate. For example, the genus ''Trillium'' is partitioned into two subgenera, the sessile-flowered trilliums (''Trillium'' subg. ''Sessilium'') and the pedicellate-flowered trilliums. Sessile leaves lack petioles (leaf stalks). A leaf that is not sessile is petiolate. For example, the leaves of most monocotyledons lack petioles. The term sessility is also used in mycology to describe a fungal fruit body that is attached to or seated directly on the surface of the substrate, lacking a supporting stipe or pedicel Pedicle or pedicel may refer to: Human anatomy *Pedicle of vertebral arch, the segment between the transvers ...
