Therophyte

an annual plant that survives unfavorable seasons—cold or dry seasons—in seed form. Most therophytes are of Mediterranean origin and are characteristic of deserts, semideserts, and southern steppes of the northern hemisphere, where they include many Cruciferae and Papaveraceae. In the forest zone therophytes are represented mainly by field weeds, for example, cornflower, pennycress, and stork’s-bill.
