Carex Brevior
''Carex brevior'', known as shortbeak sedge and plains oval sedge, is a species of sedge native to North America. The specific epithet ''brevior'' means "shorter" in Latin. Description ''Carex brevior'' forms dense tufts with short-prolonged rhizomes, the clumps sometimes appearing elongated. The flowering culms are tall with 3 to 5 leaves per culm. Few vegetative culms are produced and unlike some other sedges, they are not strikingly 3-ranked. The leaf sheaths are white and papery and the ligule is long. The inflorescence is open, brown, up to long with between 3 and 7 distant, distinct spikes per culm. Each spike is ovoid or ellipsoide, typically attenuate at the base and acute or rounded at the tip, with 15–40 lenticular perigynia. The perigynia are green to reddish brown, orbiculate to broadly ovate, and typically long and across (1.2–1.8 times as long as wide). ''Carex brevior'' flowers in mid-May and early June, fruiting in the early to mid summer. A member of ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chester Dewey
Chester Dewey (October 25, 1784 – December 15, 1867) was an American botanist, antislavery activist, clergyman and educator.Makers of American Botany, Harry Baker Humphrey, Ronald Press Company, Library of Congress Card Number 61-18435 Early life Chester Dewey was born in Sheffield, Massachusetts, on October 25, 1784, to Elizabeth Owen and Stephen Dewey. He studied for the ministry at Williams College, graduated in 1806, and officiated at Tryingham, Massachusetts. Even though he gave up preaching as his primary profession after only a few months, he never really retired from the pulpit. He also assisted his brother, Loring D. Dewey in his efforts to create a school of U.S. Blacks. For the remainder of his life he accepted frequent invitations to preach, in scores of churches in many places and did nearly as much work of this kind as if preaching were his only occupation. Dewey was professor of mathematics and natural philosophy at Williams College from 1810 to 1827. He was e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puccinia Dioicae
''Puccinia dioicae'' is a plant pathogen that causes rust on goldenrod. It is common in Iceland, where it infects ''Taraxacum'' species and ''Carex capillaris''. Pycniospores and aeciospores are found on ''Taraxacum'' sp., and uredospores and teliospore Teliospore (sometimes called teleutospore) is the thick-walled resting spore of some fungi ( rusts and smuts), from which the basidium arises.

Infusion
Infusion is the process of extracting chemical compounds or flavors from plant material in a solvent such as water, oil or alcohol, by allowing the material to remain suspended in the solvent over time (a process often called steeping). An infusion is also the name for the resultant liquid. The process of infusion is distinct from both decoction—a method of extraction involving boiling the plant material—and percolation, in which water is passed through the material (as in a coffeemaker). History The first recorded use of essential oils was in the 10th or 11th century by the Persian polymath Avicenna, possibly in ''The Canon of Medicine''. Tea is far older than this, dating back to the 10th century BC as the earliest recorded reference. Preparation techniques Infusion is a chemical process that uses botanicals (typically dried herbs, flowers or berries) that are volatile and release their active ingredients readily in water, oil, or alcohol. In this process, a liquid i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gynecological
Gynaecology or gynecology (see spelling differences) is the area of medicine that involves the treatment of women's diseases, especially those of the reproductive organs. It is often paired with the field of obstetrics, forming the combined area of obstetrics and gynecology (OB-GYN). The term comes from Greek and means "the science of women". Its counterpart is andrology, which deals with medical issues specific to the male reproductive system. Etymology The word "gynaecology" comes from the oblique stem (γυναικ-) of the Greek word γυνή (''gyne)'' semantically attached to "woman", and ''-logia'', with the semantic attachment "study". The word gynaecology in Kurdish means "jinekolojî", separated word as "jin-ekolojî", so the Kurdish "jin" called like "gyn" and means in Kurdish "woman". History Antiquity The Kahun Gynaecological Papyrus, dated to about 1800 BC, deals with gynaecological diseases, fertility, pregnancy, contraception, etc. The text is divided into thir ...

Iroquois
The Iroquois ( or ), officially the Haudenosaunee ( meaning "people of the longhouse"), are an Iroquoian-speaking confederacy of First Nations peoples in northeast North America/ Turtle Island. They were known during the colonial years to the French as the Iroquois League, and later as the Iroquois Confederacy. The English called them the Five Nations, comprising the Mohawk, Oneida, Onondaga, Cayuga, and Seneca (listed geographically from east to west). After 1722, the Iroquoian-speaking Tuscarora people from the southeast were accepted into the confederacy, which became known as the Six Nations. The Confederacy came about as a result of the Great Law of Peace, said to have been composed by Deganawidah the Great Peacemaker, Hiawatha, and Jigonsaseh the Mother of Nations. For nearly 200 years, the Six Nations/Haudenosaunee Confederacy were a powerful factor in North American colonial policy, with some scholars arguing for the concept of the Middle Ground, in that Europe ...

Southeastern United States
The Southeastern United States, also referred to as the American Southeast or simply the Southeast, is a geographical region of the United States. It is located broadly on the eastern portion of the southern United States and the southern portion of the eastern United States. It comprises at least a core of states on the lower East Coast of the United States and eastern Gulf Coast. Expansively, it reaches as far north as West Virginia and Maryland (bordered to north by the Ohio River and Mason–Dixon line), and stretching as far west as Arkansas and Louisiana. There is no official U.S. government definition of the region, though various agencies and departments use different definitions. Geography The U.S. Geological Survey considers the Southeast region to be the states of Alabama, Florida, Georgia, Arkansas, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, and Tennessee, plus Puerto Rico and the United States Virgin Islands.

Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to mean tre ...

Prairie
Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Ukraine, Russia and Kazakhstan. Lands typically referred to as "prairie" tend to be in North America. The term encompasses the area referred to as the Geography of North America, Interior Lowlands of Canada, the United States, and Mexico, which includes all of the Great Plains as well as the wetter, hillier land to the east. In the U.S., the area is constituted by most or all of the states of North Dakota, South Dakota, Nebraska, Kansas, and Oklahoma, and sizable parts of the states of Montana, Wyoming, Colorado, New Mexico, Texas, Missouri, Iowa, Illinois, Indiana, Wisconsin, and western and southern Minnesota.

Tamaulipas
Tamaulipas (), officially the Free and Sovereign State of Tamaulipas ( es, Estado Libre y Soberano de Tamaulipas), is a state in the northeast region of Mexico; one of the 31 states which, along with Mexico City, comprise the 32 Federal Entities of Mexico. It is divided into 43 municipalities. Tamaulipas is bordered by the states of Nuevo León to the west, San Luis Potosí to the southwest, and Veracruz to the southeast. To the north, it has a stretch of the U.S.–Mexico border with the state of Texas, and to the east it is bordered by the Gulf of Mexico. In addition to the capital city, Ciudad Victoria, the state's largest cities include Reynosa, Matamoros, Nuevo Laredo, Tampico, and Mante. Etymology The name Tamaulipas is derived from ''Tamaholipa'', a Huastec term in which the ''tam-'' prefix signifies "place (where)". No scholarly agreement exists on the meaning of ''holipa'', but "high hills" is a common interpretation. Another explanation of the state name is tha ...

Rust Fungus
Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales (previously known as Uredinales). An estimated 168 rust genera and approximately 7,000 species, more than half of which belong to the genus ''Puccinia'', are currently accepted. Rust fungi are highly specialized plant pathogens with several unique features. Taken as a group, rust fungi are diverse and affect many kinds of plants. However, each species has a very narrow range of hosts and cannot be transmitted to non-host plants. In addition, most rust fungi cannot be grown easily in pure culture. A single species of rust fungi may be able to infect two different plant hosts in different stages of its life cycle, and may produce up to five morphologically and cytologically distinct spore-producing structures viz., spermogonia, aecia, uredinia, telia, and basidia in successive stages of reproduction. Each spore type is very host specific, and can typically infect only one kind of plant. Rust fungi are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
