Another large natural family of plants, the milkworts, have a pretty representative in the meadows in the Cuckoo-flower (Cardamine pratensis). Its leaves are pennate, and the lilac-colored flowers contain four large and two short stamens; the fruit is a pod. Upon woody pastures we also often find the Orchis (Orchis Morio). From the two oval tubers a stem arises enclosed in sheath-like leaves. At the top of the stem are the curiously formed flowers, which are fructified by insects in a very peculiar and striking manner. The somewhat unattractive Sour-Sorrel (Rumex Acetosa), Fig. 13, is well known, and its soft stem and juicy leaves are sometimes eaten by children. The leaves are arrow-shaped; the small flowers are reddish in color.
