For the details and classification of the multitude of facts, the student is referred to Masters' Vegetable Teratology, Ray Society, 1869, and the pages of the Gardeners' Chronicle since that date.
Concerning torsions, etc., the student should read De Vries, "On Biastrepsis in its Relation to Cultivation," Ann. of Bot., Vol. XIII., 1899, p. 395, and "Hybridising of Monstrosities," Hybrid Conference Report, Roy. Hort. Soc., 1900, Vol. XXIV., p. 69.
