Abstract
The Euphorbia species occurring in California need nomenclatorial corrections. A partial synonomy. without combinations in the segregate genera, is given. A new species, species new to California, and range extensions of species known to occur in the state are recorded. These notes are excerpts from an extended study of the section Anisophyllum. The synonyms given are, in most cases, based on a critical study of the type or isotype concerned.
