Cerastium is a genus of annual, winter annual, or perennial plants belonging to the family Caryophyllaceae. They are commonly called mouse-ear chickweed. Species are found nearly worldwide but the greatest concentration is in the northern temperate regions. There are about 200 species. A number are common weeds in fields and on disturbed ground. Using only the above description and what you know about the world, "Mouse-eared chickweed are commonly found in the northern hemisphere but are found worldwide too." is definitely correct, incorrect, or inconclusive?
