It is also known as Clayton's sweetroot, sweet cicely, or woolly sweet cicely a name it shares with other members of its genus ''Osmorhiza''. Description ''Osmorhiza claytonii'' is a herbaceous perennial tall and pubescent. Leaves are large, compound, deeply divided, and dentate. Flowers are small , white, and clustered with others on a long-stalked umbel. Its native habitats include rich woods and wooded slopes. The leaves are yellowish green. There are white hairs on the stem and to a lesser extent on the leaves as well. It is ternately branched, having three-leafed branches. When broken it has an anise like smell or flavor. The seeds of this plant have barbs on the end allowing them to stick to clothing, fur, or feathers.

André Michaux
André Michaux (' → ahn- mee-; sometimes Anglicisation, anglicised as Andrew Michaud; 8 March 174611 October 1802) was a French botanist and explorer. He is most noted for his study of North American flora. In addition Michaux collected specimens in England, Spain, France, and even Persia. His work was part of a larger European effort to gather knowledge about the natural world. Michaux's contributions include ''Histoire des chênes de l'Amérique'' (1801; "The Oaks of North America") and ''Flora Boreali-Americana'' (1803; "The Flora of North America") which continued to be botanical references well into the 19th century. His son, François André Michaux, also became an authoritative botanist. Biography Michaux was born in Satory, part of Versailles (city), Versailles, Yvelines, where his father managed farmland on the king's estate. Michaux was trained in the agricultural sciences in anticipation of his one-day assuming his father's duties, and received a basic classical 18 ...

Papilio Polyxenes
''Papilio polyxenes'', the (eastern) black swallowtail, American swallowtail or parsnip swallowtail, is a butterfly found throughout much of North America. An extremely similar-appearing species, '' Papilio joanae'', occurs in the Ozark Mountains region, but it appears to be closely related to ''Papilio machaon'', rather than ''P. polyxenes''. The species is named after the figure in Greek mythology, Polyxena (pron.: /pəˈlɪksɨnə/; Greek: Πολυξένη), who was the youngest daughter of King Priam of Troy. Its caterpillar is called the parsley worm because the caterpillar feeds on parsley. The ''Papilio polyxenes'' demonstrates polyandry and a lek mating system, showing no male parental care and display sites. Females are therefore able to choose males based on these sites and males are the only resource the females find at these sites. Taxonomy ''Papilio polyxenes'' is part of the tribe Papilionini of the swallowtail butterfly family, Papilionidae. The members of this tr ...

Flora Of The Appalachian Mountains
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) wa ...

Pistil
Gynoecium (; ; : gynoecia) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are ...

Seeds
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted. The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate it. Many structures commonly referred to as "seeds" are actuall ...

Anise
Anise (; '), also called aniseed or rarely anix, is a flowering plant in the family Apiaceae native to the eastern Mediterranean region and Southwest Asia. The flavor and aroma of its seeds have similarities with some other spices and herbs, such as star anise, fennel, liquorice, and tarragon. It is widely cultivated and used to flavor food, candy, and alcoholic drinks, especially around the Mediterranean. Etymology The name "anise" is derived via Old French from the Latin words or from Greek ''ánēthon'' referring to dill. An obsolete English word for anise is ''anet'', also coming from ''anīsum''. Botany Anise is an herbaceous annual plant growing to or more. The leaves at the base of the plant are simple, long and shallowly lobed, while leaves higher on the stems are feathery or lacy, pinnate, divided into numerous small leaflets. Both leaves and flowers are produced in large, loose clusters. The flowers are either white or yellow, approximately in diameter ...
