Erigeron Strigosus
''Erigeron strigosus'' is a species of flowering plant in the family Asteraceae known by the common names prairie fleabane, common eastern fleabane, and daisy fleabane. ''Erigeron strigosus'' is native to eastern and central North America as far west as Manitoba, Idaho and Texas. It has also become naturalized in western North America as well as in Europe and China as a somewhat weedy naturalized species. ''Erigeron strigosus'' is an annual or biennial herb reaching heights of up to 80 cm (32 inches). It has hairy, petioled, non-clasping, oval-shaped leaves a few centimeters long mostly on the lower part of the plant. One plant can produce as many as 200 flower heads in a spindly array of branching stems. Each head is less than a centimeter (0.4 inches) wide, containing 50–100 white, pink, or blue ray florets surrounding numerous yellow disc florets. ;Varieties *''Erigeron strigosus'' var.

Cedars Of Lebanon State Park
Cedars of Lebanon State Park is a state park in Wilson County, Tennessee, in the southeastern United States. It consists of situated amidst the Cedars of Lebanon State Forest. The park and forest are approximately south of Lebanon, Tennessee. Cedars of Lebanon State Forest is known for its cedar glades, a unique type of ecosystem that has adapted to the thin (or nonexistent) soil layers that often occur in the eastern Central Basin. These glades are typically flanked by thick stands of red cedar, a type of juniper tree that can survive in soil layers too thin to support most large wooded plants. The presence of the red cedar in the basin reminded the region's early Euro-American settlers of the Lebanese cedar forests of Biblical fame. Geographical setting Cedars of Lebanon State Park is situated in the eastern Central Basin approximately west of the eastern Highland Rim, east of Nashville and north of Murfreesboro. U.S. Route 231, which runs north-to-south, splits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower Heads
A pseudanthium (; : pseudanthia) 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 zygomorphic and ...

Flora Of The Eastern United States
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or '' skin flora'' for purposes of specificity. 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) ...

Erigeron
''Erigeron'' () is a large genus of plants in the composite family (Asteraceae). It is placed in the tribe Astereae and is closely related to the Old World asters (''Aster (genus), Aster'') and the true daisies (''Bellis''). The genus has a cosmopolitan distribution, and the highest diversity occurs in North America. Etymology Its English name, fleabane, is shared with related plants in several other genera. It appears to be derived from a belief that the dried plants repelled fleas or that the plants were poisonous to fleas. The generic name ''Erigeron'' is derived from the Ancient Greek words (''êri'') "early in the morning" and (''gérōn'') "old man", a reference to the appearance of the white hairs of the fruit soon after flowering or possibly alluding to the early appearance of the seed heads. The noun is grammatical gender, masculine, so that specific epithets should have masculine endings (e.g. ''glaucus'') to Agreement (linguistics)#Gender, agree with it. However, ...

Karyotype
A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities. A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are generally organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography in the metaphase of the cell cycle, and results in a photomicrographic (or simply micrographic) karyogram. In contrast, a schematic karyogram is a designed graphic representation of a karyotype. In schematic karyograms, just one of the sister chromatids of each chromosome is generally shown for brevity, and in reality they are generally so close together that they look as ...

Disc Floret
Asteraceae () is a large family of flowering plants that consists of over 32,000 known species in over 1,900 genera within the order Asterales. 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. The Asteraceae were first described in the year 1740 and given the original name Compositae. The family is commonly known as the aster, daisy, composite, or sunflower family. Most species of Asteraceae are herbaceous plants, and may be annual, biennial, or perennial, 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. Their common primary characteristic is compound flower heads, technically known as capitula, consisting of sometimes hundreds ...
