White varieties of many species of blue-bells and gentians are found not rarely, white-flowering plants of heather, both of Erica Tetralix and Calluna vulgaris occur on European heaths; white flowers of Brunella vulgaris, Ononis repens, Thymus vulgaris and others may be seen in many localities in the habitats of the colored species.
Even in wild plants, as in Erodium, Calluna, Brunella and others, a botanist may recognize the rare white-flowered variety by the pure green color of the leaves, at times when it is not in flower. Some sorts of peas bear colored flowers and a red mark on the stipules of their leaves.
