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 ...

Polygalaceae
The Polygalaceae or the milkwort family are made up of flowering plants in the order Fabales. They have a near-cosmopolitan range, with about 27 genera and ''ca''. 900 known species of herbs, shrubs and trees. Over half of the species are in one genus, ''Polygala'', the milkworts. The family was first described in 1809 by Johann Hoffmansegg and Johann Link. In 1896, Robert Chodat split it into 3 tribes. A fourth tribe was split off from the tribe Polygaleae in 1992. Under the Cronquist classification system, Polygalaceae were treated in a separate order of their own, Polygalales. Currently, according to the Angiosperm Phylogeny Group, the family belongs in Fabales. Description ''Polygalaceae'' are annual or perennial herbs, shrubs, shrublets, and small trees. Its zygomorphic, hermaphrodite, bisexual flowers have 3-5 petals and 5 sepals. Its leaves are usually alternate, but may be opposite, fascicled, or verticillate. Each flower usually contain ...

Cleistogamous
Cleistogamy is a type of automatic self-pollination of certain plants that can propagate by using non-opening, self-pollinating flowers. Especially well known in peanuts, peas, and pansies, this behavior is most widespread in the grass family. However, the largest genus of cleistogamous plants is ''Viola''. The more common opposite of cleistogamy, or "closed marriage", is called chasmogamy, or "open marriage". Virtually all plants that produce cleistogamous flowers also produce chasmogamous ones.Meeuse, Bastiaan and Sean Morris. 1984. The sex life of flowers. New York, NY: Facts on File Publishers. pp 110-111. The principal advantage of cleistogamy is that it requires fewer plant resources to produce seeds than does chasmogamy, because development of petals, nectar and large amounts of pollen is not required. This efficiency makes cleistogamy particularly useful for seed production on unfavorable sites or adverse conditions. ''Impatiens capensis,'' for example, has been o ...

Flora Of Ontario
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 ...
