Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Typically plants are labelled with their botanical names. It may contain specialist plant collections such as cactus, cacti and other succulent plants, herb gardens, plants from particular parts of the world, and so on; there may be greenhouses, shadehouses, again with special collections such as tropical plants, alpine plants, or other exotic plants.

Neslia
''Neslia'' is a monotypic plant genus in the family Brassicaceae. The only extant species is ''Neslia paniculata'' Neslia paniculata ''Neslia paniculata'' (commonly called ball mustard) is a plant species in the family Brassicaceae. The name comes from the ball-shaped fruits that contain a single seed within an indehiscent fruit coat. It is an annual where the seeds germinate in autumn to winter and grow into a flattened rosette of leaves that develop vertical flowering stems in the spring. These can be up to 1 metre tall. The flowers open in late spring/early summer and the seeds are mature by summer. It is a native plant of temperate regions of Eurasia. It can also be found in much of the northern and southern regions of the Americas, Australia and also Great Britain, Britain. It is considered a weed in many of these regions introduced from agricultural seed and can be a problem in cereal and especially other brassica crops.

Mycenastrum
''Mycenastrum'' is a fungal genus in the family Agaricaceae. The genus is monotypic, containing one widely distributed species, ''Mycenastrum corium'', known by various common names: the giant pasture puffball, leathery puffball, or tough puffball. The roughly spherical to turnip-shaped puffball-like fruit bodies grow to a diameter of . Initially covered by a thick, felted, whitish layer, the puffballs develop a characteristic checkered skin (peridium) in age. When the internal spore mass, the gleba, is firm and white, the puffball is edible, although some individuals may suffer mild gastrointestinal symptoms after eating it. As the spores mature, the gleba turns first yellowish then purplish brown. Spores are released when the peridium eventually splits open into irregularly shaped sections. Microscopically, the gleba consists of spherical, dark brown spores with rounded bumps on their surfaces, and a capillitium—intricately branched fibers that form long thorn-like spines. The ...

19th-century French Botanists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
