Conium maculatum disturbed ground. It is used as a food plant by the larvae of some Lepidoptera species, including silver-ground carpet. The poison hemlock moth ("Agonopterix alstroemeriana") feeds on the plant during its larval stage. "A. alstroemeriana" has been widely used as a biological control agent for "C. maculatum". Poison hemlock flourishes in the spring, when most other forage is gone. All plant parts are poisonous, but once the plant is dried, the poison is greatly reduced, although not gone completely. The plant is poisonous to animals that graze on it. "Conium" contains the piperidine alkaloids coniine, N-methylconiine, conhydrine, pseudoconhydrine and gamma-coniceine
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.
