Elephantella
''Pedicularis groenlandica'' is a showy flowering plant in the family Orobanchaceae commonly known as elephant's head, little pink elephant, elephantella, or similar common names inspired by the resemblance of the flower to the head of an elephant. It is also less commonly known as butterfly tongue for the long beak on the flower. Like many other plants in genus ''Pedicularis'', it is a parasitic plant and depends on host plants to survive. Description ''Pedicularis groenlandica'' is an erect plant that can grow to a height of , but may be only tall. It generally has 5–20 larger leaves that sprout directly from the base of the plant (Leaf#Arrangement on the stem, basal leaves). The leaves are narrow in outline with the widest part in the middle (blade lanceolate). The leaves have a pointed tip and are 20–150 millimeters long and 5–250 millimeters wide. They strongly resemble fern leaves being divided to the leaf central leaf vein, and sometimes the leaf segments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pedicularis Incurva
''Pedicularis'' is a genus of perennial green root parasite plants currently placed in the family Orobanchaceae (the genus previously having been placed in Scrophulariaceae ''sensu lato''). Uses Pedicularis is used medicinally in teas and smoking blends. Taxonomy The common name lousewort, applied to several species, derives from an old belief that these plants, when ingested, were responsible for lice infestations in livestock. The genus name ''Pedicularis'' is from the Latin ''pediculus'' meaning louse. Over 600 species are accepted, mostly from the wetter northern temperate zones, as well as from South America. The highest diversity is in eastern Asia, with 352 species accepted in China alone.

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botany, botanist of the 19th century. His ''Darwiniana'' (1876) was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built a ...

British America
British America collectively refers to various British colonization of the Americas, colonies of Kingdom of Great Britain, Great Britain and its predecessors states in the Americas prior to the conclusion of the American Revolutionary War in 1783. The British monarchy of the Kingdom of England and Kingdom of Scotland—later named the Kingdom of Great Britain, of the British Isles and Western Europe—governed many colonies in the Americas beginning in 1585. From 1607, numerous permanent English settlements were made, ultimately reaching from Hudson Bay, to the Mississippi River and the Caribbean Sea. Much of these territories were occupied by Indigenous peoples of the Americas, indigenous peoples, whose populations declined due to Epidemic, epidemics, wars, and massacres. In the Atlantic slave trade, England and other European empires shipped Africans to the Americas for labor in their colonies.

He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884.

Root
In vascular plants, the roots are the plant organ, organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. They are most often below the surface of the soil, but roots can also be aerial root, aerial or aerating, that is, growing up above the ground or especially above water. Function The major functions of roots are absorption of water, plant nutrition and anchoring of the plant body to the ground. Types of Roots (major rooting system) Plants exhibit two main root system types: ''taproot'' and ''fibrous'', with variations like adventitious, aerial, and buttress roots, each serving specific functions. Taproot System Characterized by a single, main root growing vertically downward, with smaller lateral roots branching off. Examples. Dandelions, carrots, and many dicot plants. Fibrous RootSystem Consists of a network of thin, branching roots that spread out from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
