Botanist
Botany, also called plant science, is the branch of natural science and biology studying plants, especially Plant anatomy, their anatomy, Plant taxonomy, taxonomy, and Plant ecology, ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists (in the strict sense) study approximately 410,000 species of Embryophyte, land plants, including some 391,000 species of vascular plants (of which approximately 369,000 are flowering plants) and approximately 20,000 bryophytes. Botany originated as history of herbalism#Prehistory, prehistoric herbalism to identify and later cultivate plants that were edible, poisonous, and medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens, often attached to Monastery, monasteries, contained plants possibly having medicinal benefit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 greenhouse, glasshouses or shadehouses, again with special collections such as tropical plants, alpine plants, or other exotic plants that are not native to that region.

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. 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 thornlike spines. The puffball grows on or in the ground in prairie or desert habitats. Although widely distributed, it is not commonly encountered. It is a threatened species in Europe. Wh ...

Étienne-Émile Desvaux
Étienne-Émile Desvaux (8 February 1830, in Vendôme – 13 May 1854, in Mondoubleau) was a French botanist. He developed an interest in botany at an early age, actively collecting plants from the age of 10. In July 1850, he earned his Bachelor of Science degree in Paris. He died on May 13, 1854 (age 24) in the town of Mondoubleau. He was the author of a monograph on Chilean grasses called "''Gramineae Chilenses''" (1853), a work that was included in Claude Gay's "''Historia fÃsica y polÃtica de Chile''". He described the genus ''Monandraira'' (synonym ''Deschampsia'') and was the binomial authority In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, altho ... of numerous grass species.

19th-century French Botanists
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It 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, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, 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 Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm ce ...
