Timothy Plowman
Timothy Charles Plowman (November 17, 1944 – January 7, 1989) was an ethnobotanist best known for his intensive work over the course of 15 years on the genus ''Erythroxylum'' in general, and the cultivated coca species in particular. He collected more than 700 specimens from South America, housed in the collection of the Field Museum of Natural History.http://fm1.fieldmuseum.org/collections/search.cgi?dest=erthroy Plowman joined the Field Museum of Natural History in 1978 where he became tenured in 1983 and was appointed Curator in 1988. He published more than 80 scientific papers (46 on ''Erythroxylum'') and served as editor for several scientific journals. He is one of the main subjects of ''One River: Explorations and Discoveries in the Amazon Rain Forest'' by Wade Davis. Both were students of Richard Evans Schultes, the father of modern ethnobotany. Plowman died of AIDS, which he contracted from pre-trip inoculations. The nightshade species ''Brunfelsia plowma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethnobotany
Ethnobotany is the study of a region's plants and their practical uses through the traditional knowledge of a local culture and people. An ethnobotanist thus strives to document the local customs involving the practical uses of local flora for many aspects of life, such as plants as medicines, foods, intoxicants and clothing. Richard Evans Schultes, often referred to as the "father of ethnobotany", explained the discipline in this way: Ethnobotany simply means ... investigating plants used by societies in various parts of the world. Since the time of Schultes, the field of ethnobotany has grown from simply acquiring ethnobotanical knowledge to that of applying it to a modern society, primarily in the form of pharmaceuticals. Intellectual property rights and benefit-sharing arrangements are important issues in ethnobotany. History The idea of ethnobotany was first proposed by the early 20th century botanist John William Harshberger. While Harshberger did perform ethnobotanical ...

Ipomoea Coccinea
''Ipomoea coccinea'' is a flowering plant in the family Convolvulaceae known by several common names including red morning glory, redstar and (ambiguously) Mexican morning glory. It was first described by Linnaeus in 1753. Description Red morning glories are fast growing, twisting climbing flowering vines that attract butterflies. The leaves are heart-shaped at the base, and commonly are three-lobed. They grow up to be about long and about half as wide. The vines can reach or more in length. The flowers are dull red with an orange throat. Red morning glory flowers are borne in clusters of a half dozen. The species name is Latin for "scarlet", and refers to the color of the flowers. Habitat and ecology ''Ipomoea coccinea'' is native to tropical America and have been introduced in much of the US. They can be found in disturbed areas along roads, stream banks, fence rows, old fields and other waste areas. Morphology ''Ipomoea coccinea'' is often confused with ''Ipomoea quam ...

Cornell University Alumni
Cornell University is a private statutory land-grant research university based in Ithaca, New York. It is a member of the Ivy League. Founded in 1865 by Ezra Cornell and Andrew Dickson White, Cornell was founded with the intention to teach and make contributions in all fields of knowledge—from the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's founding principle, a popular 1868 quotation from founder Ezra Cornell: "I would found an institution where any person can find instruction in any study." Cornell is ranked among the top global universities. The university is organized into seven undergraduate colleges and seven graduate divisions at its main Ithaca campus, with each college and division defining its specific admission standards and academic programs in near autonomy. The university also administers three satellite campuses, two in New York City and one in Education Ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychedelic Drug Researchers
Psychedelics are a subclass of hallucinogenic drugs whose primary effect is to trigger non-ordinary states of consciousness (known as psychedelic experiences or "trips").Pollan, Michael (2018). ''How to Change Your Mind: What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression, and Transcendence'' Sometimes, they are called classic hallucinogens, serotonergic hallucinogens, or serotonergic psychedelics, and the term ''psychedelics'' is used more broadly to include all hallucinogens; this article uses the narrower definition of ''psychedelics''. Psychedelics cause specific psychological, visual, and auditory changes, and often a substantially altered state of consciousness.Leary, Timothy; Metzner, Ralph (1964). ''The Psychedelic Experience: A Manual Based on The Tibetan Book of the Dead'' Psychedelic states are often compared to meditative, psychodynamic or transcendental types of alterations of mind. The "classical" psychedelics, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

This is a list of botanists who have Wikipedia articles, in alphabetical order by surname. The List of botanists by author abbreviation is mostly a list of plant taxonomists because an author receives a standard abbreviation only when that author originates a new plant name.

Commelinaceae
Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with about 731 known species in 41 genera. Well known genera include '' Commelina'' (dayflowers) and '' Tradescantia'' (spiderworts). The family is diverse in both the Old World tropics and the New World tropics, with some genera present in both. The variation in morphology, especially that of the flower and inflorescence, is considered to be exceptionally high amongst the angiosperms. The family has always been recognized by most taxonomists. The APG III system of 2009 (unchanged from the APG system of 1998), also recognizes this family, and assigns it to the order Commelinales in the clade commelinids in the monocots. The family counts several hundred species of herbaceous plants. Many are cultivated as ornamentals. The stems of these plants are g ...
