Lithospermum Bejariense
''Lithospermum bejariense'', known by the common name western marbleseed, is a species of flowering plant in the borage family. It is native to the Southeastern United States, where it is in found rocky barrens and glades in calcareous Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines. In zoology ''Calcareous'' is used as an adje ... areas. It is distinguished from other closely related ''Lithospermum'' by its flowers that are 1–2 cm long and its spreading 2–4 cm stem pubescence.

Alphonse Pyramus De Candolle
Alphonse Louis Pierre Pyramus (or Pyrame) de Candolle (28 October 18064 April 1893) was a French-Swiss botanist, the son of the Swiss botanist Augustin Pyramus de Candolle. Biography De Candolle, son of Augustin Pyramus de Candolle, first devoted himself to the study of law, but gradually drifted to botany and finally succeeded to his father's chair at the University of Geneva. He published a number of botanical works, including continuations of the ''Prodromus'' in collaboration with his son, Casimir de Candolle. Among his other contributions is the formulation, based on his father's work for the ''Prodromus'', of the first Laws of Botanical Nomenclature, which was adopted by the International Botanical Congress in 1867, and was the prototype of the current ICN. He was elected a foreign member of the Royal Swedish Academy of Sciences in 1859 and was awarded the Linnean Medal of the Linnean Society of London in 1889. He was elected a foreign member of the Royal Netherlands Aca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boraginaceae
Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees and herbs in 146, to 156 genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system it was included in Lamiales, but it is now clear that it is no more similar to the other families in this order than they are to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae in eleven distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petiol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southeastern United States
The Southeastern United States, also referred to as the American Southeast or simply the Southeast, is a geographical region of the United States. It is located broadly on the eastern portion of the southern United States and the southern portion of the eastern United States. It comprises at least a core of states on the lower East Coast of the United States and eastern Gulf Coast. Expansively, it reaches as far north as West Virginia and Maryland (bordered to north by the Ohio River and Mason–Dixon line), and stretching as far west as Arkansas and Louisiana. There is no official U.S. government definition of the region, though various agencies and departments use different definitions. Geography The U.S. Geological Survey considers the Southeast region to be the states of Alabama, Florida, Georgia, Arkansas, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, and Tennessee, plus Puerto Rico and the United States Virgin Islands. There is no official Census Bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcareous
Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines. In zoology ''Calcareous'' is used as an adjectival term applied to anatomical structures which are made primarily of calcium carbonate, in animals such as gastropods, i.e., snails, specifically about such structures as the operculum, the clausilium, and the love dart. The term also applies to the calcium carbonate tests of often more or less microscopic Foraminifera. Not all tests are calcareous; diatoms and radiolaria have siliceous tests. The molluscs are calcareous, as are calcareous sponges ( Porifera), that have spicules which are made of calcium carbonate. In botany ''Calcareous grassland'' is a form of grassland characteristic of soils containing much calcium carbonate from underlying chalk or limestone rock. In medicine The term is used in pathology, for example i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithospermum
''Lithospermum'' is a genus of plants belonging to the family Boraginaceae. The genus is distributed nearly worldwide, but most are native to the Americas and the center of diversity is in the southwestern United States and Mexico. Species are known generally as gromwells or stoneseeds. Taxonomy There are about 50, to 60 species in the genus.Cohen, J. I., (2012)Comparative floral development in ''Lithospermum'' (Boraginaceae) and implications for the evolution and development of heterostyly.''American Journal of Botany'' 99(5), 797–805. Some species, such as '' Lithospermum arvense'', are sometimes classified in the genus '' Buglossoides'', but that genus is subsumed into ''Lithospermum'' by works such as the ''Flora of China''. In addition, a 2009 molecular study showed that the genus ''Onosmodium'' should be included within ''Lithospermum''. Species include: *'' Lithospermum arvense'' (syn. ''Buglossoides arvensis'') – field gromwell, corn gromwell *'' Lithospermum azu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of The Southeastern United States
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
