Book excerpt: Excerpt from Stock-Poisoning Plants of California The writers have chosen to define a poisonous plant as one containing some specific substance which, when eaten in sufficient quantity may pro duce a morbid, noxious, or deadly effect on the animal. When the result is only illness the effect is spoken of as toxic; and when death ensues the dosage is referred to as lethal. Merely mechanically injurious plants, such as some grasses, with prominent, penetrating awns, and those which occasionally cause bloat, like the clovers, are not included in this paper. The chief object of this bulletin is to summarize the present knowl edge and field observations of the stock-poisoning plants of the state. Although the total number of poisonous species occurring on ranges of California is large, most of the deaths among range livestock are caused by species embraced in relatively few genera. In order to bring to the stockman's attention the poisonous species most. Generally harmful on the range, the material has been segregated into three parts. The plants of primary importance are discussed in the first section. Then those of secondary consideration are presented. The third section includes the plants which are more local or which cause only occasional livestock losses. When discussed at length the material under the first two groups is treated systematically under the following headings: Description and distribution of the genus; description of species; nature of injury and animals affected; and preventive measures. Maps showing in detail the distribution over the state of the more im portant species, accompany the descriptive material.
