Christian Gottfried Daniel Nees Von Esenbeck
Christian Gottfried Daniel Nees von Esenbeck (14 February 1776 – 16 March 1858) was a prolific Germany, German botanist, physician, zoologist, and natural philosopher. He was a contemporary of Goethe and was born within the lifetime of Carl Linnaeus, Linnaeus. He described approximately 7,000 plant species (almost as many as Linnaeus himself). His last official act as president of the German Academy of Natural Scientists Leopoldina was to admit Charles Darwin as a member. He was the author of numerous monographs on botany and zoology and majority of his best-known works deal with fungi. Biography Nees von Esenbeck was born in Schloss Reichenberg near Reichelsheim (Odenwald) in Hesse, Germany. He showed an early interest in science and, after receiving his primary education in Darmstadt, went on to the University of Jena and obtained his degree in biology (natural history) and medicine in 1800. He practiced as a physician for Francis I (Erbach-Erbach), but he had developed a gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monagas
Monagas State (, ) is one of the 23 states of Venezuela. Monagas State covers a total surface area of and, as of the 2011 census, had a population of 905,443. Monagas State is surrounded by Sucre State in the north, Anzoátegui State in the west and south, Bolívar State in the south, Delta Amacuro State in the south and east and the Paria Gulf in the northeast.

The capital of the state is Maturín. History Pre-colonial period Monagas dates back to the settlement of the territory by indigenous people of different ethnic groups hundreds of years ago, among which are the Warao and Kalina people, who mainly settled in the Orinoco Delta, and the people in the north of the state. The first aboriginal people to found a presence in the northern part of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grasses Of North America
Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, including staple foods from domesticated cereal crops such as maize, wheat, rice, oats, barley, and millet for people and as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panicoideae
Panicoideae is the second-largest subfamily of the grasses with over 3,500 species, mainly distributed in warm temperate and tropical regions. It comprises some important agricultural crops, including sugarcane, maize (or corn), sorghum, and switchgrass. C4 photosynthesis evolved independently a number of times in the subfamily, which presumably had a C3 ancestor. Description The ligule has a fringe of hairs. The inflorescence is branched around a common axis. The spikelets are all alike with two bisexual florets that are joined below the glumes (the outer floral envelopes). The lower glume is shorter than the spikelet. Systematics and taxonomy Within the PACMAD clade of grasses, the Panicoideae are sister to a clade made of the four subfamilies Arundinoideae, Chloridoideae, Danthonioideae, and Micrairoideae. A modern phylogenetic classification divides the Panicoideae in twelve tribes corresponding to monophyletic clades; two genera, '' Chandrasekharania'' and '' Ja ...

List Of Poaceae Genera
Poaceae, also known as the true grasses, is the fourth largest plant family in the world with around 12,000 species and roughly 800 genera. They contain, among others, the cereal crop species and other plants of economic importance, such as the bamboos, and several important weeds. Grasses probably originated in the understory of tropical rainforests in the Late Cretaceous, but have since come to occupy a wide range of different habitats. Notably, they are the dominant species in grasslands, open habitats that cover around one fifth of the earth's terrestrial surface. The C4 photosynthesis, C4 photosynthetic pathway has evolved at least 22 times independently in the grasses; C4 species are more competitive than C3 plants in open habitats with high light intensity and warm temperatures. The deeper relationships in the family have been resolved by recent molecular phylogenetic work. This has been translated into a modern classification which divides the grasses into twelve subfa ...
