Asclepias Hirtella
''Asclepias hirtella'', commonly called the tall green milkweed, is a species of flowering plant in the milkweed genus and dogbane family (Apocynaceae). It is native to Canada and the United States, where its range is concentrated in the Midwest and Upper South. Description ''Asclepias hirtella'' is a tall perennial, reaching 3 feet in height. It has many narrow, linear leaves that are produced alternately on the stem. Its flowers in lateral umbels with slender peduncles. Each stem may have 2 to 10 umbels and each umbel may have 30 to 100 flowers. The flowers lack horns and are greenish to slightly purplish in color. It flowers June through August. This species closely resembles '' Asclepias longifolia'', and it is occasionally treated to be a subspecies of it. ''Asclepias longifolia'' is restricted to the Southeastern Coastal Plain, and it differs from ''Asclepias hirtella'' in its fewer and smaller flower umbels, and its glabrous leaves. Habitat ''Asclepias hirtella'' is f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Milkweed
''Asclepias'' is a genus of herbaceous, perennial, flowering plants known as milkweeds, named for their latex, a milky substance containing cardiac glycosides termed cardenolides, exuded where cells are damaged. Most species are toxic to humans and many other species, primarily due to the presence of cardenolides, although, as with many such plants, there are species that feed upon them (e.g. their leaves) and from them (e.g. their nectar). Most notable are monarch butterflies, who use and require certain milkweeds as host plants for their larvae. The genus contains over 200 species distributed broadly across Africa, North America, and South America. It previously belonged to the family Asclepiadaceae, which is now classified as the subfamily Asclepiadoideae of the dogbane family, Apocynaceae. The genus was formally described by Carl Linnaeus in 1753, who named it after Asclepius, the Greek god of healing. Flowers Members of the genus produce some of the most complex flowe ...

Apocynaceae
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arrow poisons. Some genera of Apocynaceae, such as '' Adenium'', bleed clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midwest
The Midwestern United States, also referred to as the Midwest or the American Midwest, is one of four Census Bureau Region, census regions of the United States Census Bureau (also known as "Region 2"). It occupies the northern central part of the United States. It was officially named the North Central Region by the Census Bureau until 1984. It is between the Northeastern United States and the Western United States, with Canada to the north and the Southern United States to the south. The Census Bureau's definition consists of 12 states in the north central United States: Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin. The region generally lies on the broad Interior Plain between the states occupying the Appalachian Mountains, Appalachian Mountain range and the states occupying the Rocky Mountains, Rocky Mountain range. Major rivers in the region include, from east to west, the Ohio River, the Upper Mis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper South
The Upland South and Upper South are two overlapping cultural and geographic subregions in the inland part of the Southern and lower Midwestern United States. They differ from the Deep South and Atlantic coastal plain by terrain, history, economics, demographics, and settlement patterns. The term Upper South is a geographic term: the Southern states that are geographically north of the Lower or Deep South: primarily Virginia, West Virginia, Kentucky, North Carolina, and Tennessee, and to a lesser extent the District of Columbia and Maryland. The Upland South is defined by elevation above sea level; it is west of the population centers on the east coast. It has its own history and culture. It includes most of West Virginia and Kentucky, and parts of Virginia, Tennessee, North Carolina, Arkansas, Missouri, and Oklahoma. Upland South outposts were settled along the shores of the Ohio River. Geography There is a slight difference in usage between the two terms "Upland South" and ...

Asclepias Longifolia
''Asclepias longifolia'', the longleaf milkweed, is a flowering plant native to the southern United States from Texas to Delaware. It is rare in the north end of its range and is presumed to be extinct Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and ... in Delaware.

Limestone Glades
A calcareous glade is a type of ecological community that is found in the central Eastern United States. Calcareous glades occur where bedrock such as limestone occurs near or at the surface, and have very shallow and little soil development. Due to the shallow soil and the extreme conditions created by it, trees are often unable to grow in the glades. This creates a habitat that is usually sunny, dry, and hot. Calcareous glade vegetation is more similar to that of a desert habitat than a grassland, being dominated by small spring annuals with occasional geophytic or succulent perennials. The usage of the words "glades" and "barrens" to describe dry, rocky communities in the United States is not uniform, and the terms are often used interchangeably. Calcareous glade communities can intergrade with dry rocky prairies, particularly in sloping habitats. Due to their unsuitability for agriculture, glade communities have survived to the present day at a higher rate than deeper-soil ...
