Cyclospermum leptophyllum is an annual herb that is not native to California.
[Wikipedia]: The 1889 book 'The Useful Native Plants of Australia’ records that a common name included "Wild Parsley" and that "It is worthy of note that this plant (in common with others of the genus) is sometimes acrid and injurious when grown in damp soils. It is, doubtless, capable of much improvement by careful cultivation. This plant is not endemic to Australia." (link added by Mary Ann Machi)
