Scientific names follow TJM2 and supplements 1-3¹; we also include plants and names not treated by TJM2 and supplements. Following the Marin Flora, 2nd ed, 2007: “We include here as naturalized species those that are established and have a true competitive status without cultivation whether the plant is aggressively spreading or seems only passively and locally established. . . . Experience has shown that the waifs of today may become the weeds of tomorrow.”
