Examples from literature

• Chestnuts rarely set any nuts that produce mature seed from their own pollen but depend on cross-pollination. 
• In the large seed gardens the varieties of flowers raised are either many or cross-pollination is carried on. 
• Notice how the stigma and the anthers are kept as far as possible from each other to guard against self-pollination and to insure cross-pollination. 
• The ablest patent lawyer in America might not know the difference between a bud and a graft, a layer or cross-pollination. 
• They eat the pollen, which is supposed to taste as it smells and thus as they go from flower to flower they carry pollen from one blossom to another and so secure for the plant cross-pollination.
