Clethraceae
The Clethraceae are a small family of flowering plants in the order Ericales, composed of two genera, '' Clethra'' and '' Purdiaea'', with approximately 75 species. They are native to warm temperate to tropical regions of Asia and the Americas, with one species also on Madeira. In the past, most botanists included only ''Clethra'' in the family, but recent research has shown ''Purdiaea'', previously placed in the closely related family Cyrillaceae The Cyrillaceae are a small family of flowering plants in the order Ericales, native to warm temperate to tropical regions of the Americas. The family comprises two genera, '' Cliftonia'' and '' Cyrilla'', each containing a single species, ''Clif ..., is more closely allied to ''Clethra''.

Ericales Families
The Ericales are a large and diverse order of flowering plants in the asterid group of the eudicots. Well-known and economically important members of this order include tea and ornamental camellias, persimmon, ebony, blueberry, cranberry, lingonberry, huckleberry, kiwifruit, Brazil nut, argan, sapote, azaleas and rhododendrons, heather, heath, impatiens, phlox, Jacob's ladder, primroses, cyclamens, shea, sapodilla, pouterias, and trumpet pitchers. The order includes 22 families, according to the APG IV system of classification. The Ericales include trees, bushes, lianas, and herbaceous plants. Together with ordinary autophytic plants, they include chlorophyll-deficient mycoheterotrophic plants (e.g., '' Sarcodes sanguinea'') and carnivorous plants (e.g., genus '' Sarracenia''). Mycorrhizal associations are quite common among the order representatives, and three kinds of mycorrhiza are found exclusively among Ericales (namely, ericoid, arbutoid and monotropoid ...

Purdiaea
''Purdiaea'' is a genus of flowering plants in the family Clethraceae described as a genus in 1846. It is one of two genera in this family, and was formerly classified in the related family Cyrillaceae. ''Purdiaea'' is native to tropical regions of the Caribbean (with the highest species diversity on Cuba), Central America and northern South America, further south than the related genus ''Clethra'', the only other genus of this family. The genus is composed of shrubs and small trees with alternating leaves. ;Selected species * '' Purdiaea belizensis'' ( A.C.Sm. & Standl.)

Cyrillaceae
The Cyrillaceae are a small family of flowering plants in the order Ericales, native to warm temperate to tropical regions of the Americas. The family comprises two genera, '' Cliftonia'' and '' Cyrilla'', each containing a single species, ''Cliftonia monophylla'' and '' Cyrilla racemiflora''. However, additional species of ''Cyrilla'' are now often recognized and the genus is in need of taxonomic revision. In the past, many botanists included a third genus, '' Purdiaea'', in the family, though recent research has shown this genus is better placed in the closely related family Clethraceae. __TOC__ Fossil record Fossil ''Cyrilla'' and ''Cliftonia'' leaves, wood and pollen have been reported from the Neogene Lower Rhine region brown coal. Leaf fragments of ''Cyrilla'' have been found frequently in brown coals of central Europe. The Cyrillaceae formed part of the Tertiary bog flora where they constituted an important component of the shrubby vegetation. Among fossil ''Cyrilla'' fro ...

Johann Friedrich Klotzsch
Johann Friedrich Klotzsch (9 June 1805 – 5 November 1860) was a German pharmacist and botanist. His principal work was in the field of mycology, with the study and description of many species of mushroom. Klotzsch was born in Wittenberg. Originally trained as a pharmacist, he later enrolled in pharmaceutical and botanical studies in Berlin. In 1830–32 he was curator of William Jackson Hooker's herbarium at the University of Glasgow. Beginning in 1834 he collected plants in Saxony, Bohemia, Austria, Styria and possibly Hungary. In 1838 he replaced Adelbert von Chamisso (1781–1838) as curator and director of the Royal Herbarium in Berlin. The plant genus '' Klotzschia'' from the family Apiaceae, and some plant species like '' Eugenia klotzschiana'' or '' Acianthera klotzschiana'' are named in his honour.

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...

Americas
The Americas, sometimes collectively called America, are a landmass comprising the totality of North America and South America.''Webster's New World College Dictionary'', 2010 by Wiley Publishing, Inc., Cleveland, Ohio. When viewed as a single continent, the Americas or America is the 2nd largest continent by area after Asia, and is the 3rd largest continent by population. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their Lists of islands of the Americas, associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon basin, Amazon, St. Lawrence River–Great Lakes, Mississippi River System, Mississippi, and Río de la Plata Basin, La Plata basins.
