Alkaloid ("Agonopterix alstroemeriana)." This moth feeds on its highly toxic and alkaloid-rich host plant poison hemlock ("Conium maculatum") during its larval stage. "A. asltroemeriana" may benefit twofold from the toxicity of the naturally-occurring alkaloids, both through the unpalatability of the species to predators and through the ability of "A. alstroemeriana" to recognize "Conium maculatum" as the correct location for oviposition. Medical use of alkaloid-containing plants has a long history, and, thus, when the first alkaloids were isolated in the 19th century, they immediately found application in clinical practice. Many alkaloids are still used in medicine, usually in the form of salts,
Hystrix (plant) Other species placed in "Hystrix" have genomes more closely resembling those of "Leymus" species, and are better placed in that genus. Currently accepted transfers include: Hystrix (plant) Hystrix was a formerly recognized genus of grass (family Poaceae). The genus "Hystrix" was created in 1794 by Conrad Moench for the species described as "Elymus hystrix" by Carl Linnaeus in 1753. Moench considered that "E. hystrix" was sufficiently distinct to be placed in a separate genus as "Hystrix patula"; the genus was to be used for species without glumes or with long setaceous glumes. Subsequently a number of other grass species were
