These North American native plants are common weeds, found on roadsides, gravelly areas, atop mulch, and in other disturbed soils. Identification: Plants are prostrate, less than 1″ (2.5 cm) high, or up to 1′ (40 cm) high. Stems vary from green to reddish to dark red, and exude a milky sap when broken. They are hairy, with hairs that point out rather than being matted, ~1/32″ (0.5-1.5 mm) long. Leaves are opposite, somewhat asymmetric, oval, ¼-¾″ (6.3-19 mm) long and one half to two thirds as wide, with widely spaced serrations. Leaves often have an irregular dark reddish blotch in the middle. Flowers are nearly imperceptible at less than ⅛″ (3.2 mm) in size. They are cyathia with four "petals" that are white or light pink, appearing from July to October. Fruits are 1/32-1/16″ (1.5-2 mm) in size, hairless, with three lobes.
