André Michaux
André Michaux (' → ahn- mee-; sometimes Anglicisation, anglicised as Andrew Michaud; 8 March 174611 October 1802) was a French botanist and explorer. He is most noted for his study of North American flora. In addition Michaux collected specimens in England, Spain, France, and even Persia. His work was part of a larger European effort to gather knowledge about the natural world. Michaux's contributions include ''Histoire des chênes de l'Amérique'' (1801; "The Oaks of North America") and ''Flora Boreali-Americana'' (1803; "The Flora of North America") which continued to be botanical references well into the 19th century. His son, François André Michaux, also became an authoritative botanist. Biography Michaux was born in Satory, part of Versailles (city), Versailles, Yvelines, where his father managed farmland on the king's estate. Michaux was trained in the agricultural sciences in anticipation of his one-day assuming his father's duties, and received a basic classical 18 ...

Anticlea Virescens
In Greek mythology, Anticlea or Anticlia (; Ancient Greek: ''Ἀντίκλεια'', literally "without fame") was a queen of Ithaca as the wife of King Laërtes. Family Anticlea was the daughter of Autolycus and Amphithea. The divine trickster and messenger of the gods, Hermes, was her paternal grandfather. Anticlea was the mother of Odysseus by Laërtes (though some say by SisyphusHyginus, ''Fabulae'' 201; Plutarch, ''Quaestiones Graecae'' 43; Suida, s.v. Sisyphus''). Ctimene was also her daughter by her husband Laertes. Mythology Early years According to Callimachus, when she was young, Anticlea served the goddess Artemis, and accompanied her in hunting, bearing arrow and quiver. According to some later sources, including a fragment of Aeschylus' lost tragedy ''The Judgment of Arms'', Odysseus was the child of Anticlea by Sisyphus, not Laërtes. In this version of the story, Autolycus, an infamous trickster, stole Sisyphus' cattle. At some point, Sisyphus recognized ...

Alkaloid
Alkaloids are a broad class of natural product, naturally occurring organic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. Alkaloids are produced by a large variety of organisms including bacteria, fungus, fungi, Medicinal plant, plants, and animals. They can be purified from crude extracts of these organisms by acid-base extraction, or solvent extractions followed by silica-gel column chromatography. Alkaloids have a wide range of pharmacology, pharmacological activities including antimalarial medication, antimalarial (e.g. quinine), asthma, antiasthma (e.g. ephedrine), chemotherapy, anticancer (e.g. omacetaxine mepesuccinate, homoharringtonine), cholinomimetic (e.g. galantamine), vasodilation, vasodilatory (e.g. vincamine), Antiarrhythmic agent, antiarrhythmic (e.g. quinidine), analgesic (e.g. morphine), antibacterial (e.g. chelerythrine), and anti-diabetic, antihyperglycemic activities (e.g. berb ...

Toxicoscordion Venenosum
''Toxicoscordion venenosum'', with the common names death camas and meadow death camas, is a species of flowering plant in the family Melanthiaceae. It is named for its well known toxic qualities, with both its common names and its scientific name referencing this. Because its nectar is also poisonous, it is mainly pollinated by the death camas miner bee, which specializes in collecting the toxic pollen for its young. It is native to western North America from New Mexico to Saskatchewan and west to the Pacific Ocean. Description ''Toxicoscordion venenosum'' is a bulb plant 20–70 centimeters tall when flowering in the spring or early summer. The underground bulbs are egg-shaped () and made of up of multiple layers protected by dried outer layers () like an onion. The plant's leaves appear very early in the spring and are narrow. Most of the leaves spring directly from the ground (basal leaves), though a few much smaller ones may attach to the flowering stem. The length of ...

Toxicoscordion Fontanum
''Toxicoscordion fontanum'', common name small-flower death camas, is a rare plant species known only from serpentine marshes in California. It is found primarily in the Coast Ranges from Mendocino County to San Luis Obispo County, with an additional report of an isolated population in the Sierra Nevada foothills in Kern County east of Bakersfield.

Toxicoscordion Brevibracteatum
''Toxicoscordion brevibracteatum'' (syn. ''Zigadenus brevibracteatus'') is a species of flowering plant known by the common name desert deathcamas. It is native to Baja California, Sonora, and California, where it grows in sandy desert habitat among creosote and Joshua trees.

Stenanthium Leimanthoides
''Stenanthium leimanthoides'' is a poisonous monocot wildflower. It is either treated as a separate species to ''Stenanthium densum'' or as a synonym of that species. A common name is pine barren deathcamas. Within the family Melanthiaceae, it is placed in the tribe Melanthieae. Molecular phylogenetic studies in the 21st century have resulted in substantial rearrangement of the species in this tribe, many being moved to different genera. ''S.''
