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,
The genus Banksia L.f. (Proteaceae) The genus Banksia L.f. (Proteaceae) The genus "Banksia" L.f. (Proteaceae) is a 1981 monograph by Alex George on the taxonomy of the plant genus "Banksia". Published by the Western Australian Herbarium as "Nuytsia" 3(3), it presented George's taxonomic arrangement of "Banksia", the first major taxonomic revision of the genus since George Bentham published his arrangement in "Flora Australiensis" in 1870. One of the most important contributions of "The Genus Banksia L.f. (Proteaceae)" was the publication of ten new species and nine new varieties of "Banksia". These were: In addition, "B. sphaerocarpa" var. "glabrescens" was redescribed as "B. incana", and "B.
