Big Bluestem
''Andropogon gerardi'', commonly known as big bluestem, is a species of tall grass native to much of the Great Plains and grassland regions of central and eastern North America. It is also known as tall bluestem, bluejoint, and turkeyfoot. Taxonomy ''Andropogon gerardi'' was formally named in 1792 by Fulgenzio Vitman. It was named for French botanist Louis Gérard, who had first described the plant from specimens that had been cultivated in Provence, France. Kew's International Plant Names Index and USDA Germplasm Resources Information Network reject the spelling ''gerardii'' and provide reasoning for ''gerardi'' as being the correct spelling for the specific epithet of this taxon. ''Andropogon gerardii'' still makes appearances in various literature, including other USDA publications. Description Big bluestem is a perennial warm-season bunchgrass. It is tolerant of a wide range of soil conditions. The main roots are deep, and the plants send out strong, tough rhizomes, so i ...

Fulgenzio Vitman
Fulgenzio Vitman (1728–1806) was an Italian clergyman and botanist. From 1763 to 1774 he taught botany at the University of Pavia, where in 1773 he founded the Orto Botanico dell'Università di Pavia, University Botanical Garden. In 1774, he developed the Orto Botanico di Brera, Brera Botanical Garden in Milan out of a former Jesuit garden, under the direction of Maria Theresa of Austria.

Spike (botany)
A raceme () or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus '' Brassica''), radish (genus '' Raphanus''), and orchid (genus '' Phalaenopsis'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ...

Fire Adaptations
Fire adaptations are traits of plants and animals that help them survive wildfire or to use resources created by wildfire. These traits can help plants and animals increase their survival rates during a fire and/or reproduce offspring after a fire. Both plants and animals have multiple strategies for surviving and reproducing after fire. Plants in wildfire-prone ecosystems often survive through adaptations to their local fire regime. Such adaptations include physical protection against heat, increased growth after a fire event, and flammable materials that encourage fire and may eliminate competition. For example, plants of the genus ''Eucalyptus'' contain flammable oils that encourage fire and hard sclerophyll leaves to resist heat and drought, ensuring their dominance over less fire-tolerant species. Dense bark, shedding lower branches, and high water content in external structures may also protect trees from rising temperatures. Fire-resistant seeds and reserve Shoot (botany), s ...

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 Romania, Ukraine, Russia, and Kazakhstan. Lands typically referred to as "prairie" (a French loan word) tend to be in North America. The term encompasses the lower and mid-latitude of the area referred to as the Interior Plains of Canada, the United States, and Mexico. It includes all of the Great Plains as well as the wetter, hillier land to the east. From west to east, generally the drier expanse of shortgrass prairie gives way to mixed grass prairie and ultimately the richer and wetter soils of the tallgrass prairie. In the U.S., the area is constituted by most or all of the states, from north to south, of North ...

Ecological Succession
Ecological succession is the process of how species compositions change in an Community (ecology), ecological community over time. The two main categories of ecological succession are primary succession and secondary succession. Primary succession occurs after the initial Colonisation (biology), colonization of a newly created habitat with no living organisms. Secondary succession occurs after a Disturbance (ecology), disturbance such as fire, habitat destruction, or a natural disaster destroys a pre-existing community. Both consistent patterns and variability are observed in ecological succession. Theories of ecological succession identify different factors that help explain why plant communities change the way they do. Succession was among the first theories advanced in ecology. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana by Henry Chandler Cowles during the late 19th century and remains a main Ecology, ecological topic of study.

Berlin Botanical Garden
The Berlin Botanic Garden and Botanical Museum () is a botanical garden in the locality of the borough of , Berlin, Germany. Constructed between 1897 and 1910 under the guidance of architect Adolf Engler, it has an area of and over 20,000 different plant species. The garden is part of the Free University of Berlin and attracts about half a million visitors annually. Historically, the garden was commonly referred to as the Dahlem Botanical Garden, a name derived from the Royal Domain of Dahlem, where it was established in the late 1890s. However, since the latter part of the 20th century, the area has been included in the Lichterfelde West neighbourhood in the Berlin-Lichterfelde district. The most well-known part of the garden is the Great Pavilion of Great Tropical Greenhouse (), and among its many tropical plants, it hosts giant bamboo. The garden complex consists of several buildings, including glass-houses with a total area of . These include the glass Cactus Pavilion a ...

Staminate
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in '' Canna iridiflora'' and ''Strelitzia nicolai''. The stamens in a flower are collectively called the an ...

Awn (botany)
An awn is a hairy or bristle-like growth on a plant. On the seeds of grasses such as barley or rye, they form foxtails which assist seed dispersal by being barbed and so sticking to passing animals. Also, the awns may twist or curl as they are wetted and dry out and this action can make fallen seeds walk until they fall into a crevice into which they then burrow. Besides grasses, other families of plants which have awns include Asteraceae such as sunflowers and Geraniaceae such as geraniums. In the latter, the awns help disperse the seeds by developing a tension which then catapults the seeds when the seed head ripens and dries out. Description In grasses, awns typically extend from the lemmas of the florets. This often makes the hairy appearance of the grass synflorescence. Awns may be long (several centimeters) or short, straight or curved, single or multiple per floret. Some biological genera are named after their awns, such as the three-awns (''Aristida''). In s ...
