Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches cyclopediaofamer04bail4 Year: 1900 ZEA ZEA 2005 from the Teosinte (EuehUvva Mexicaita), a fodder grass that is much grown iu Mexico. See Teosinte. This latter view has arisen from experiments in cross- ing Teosinte and Maize, whereby a maize-like plant has been produced, thus showing the very close alliiiity of the two species. Plants of this hybrid were tliouglil by the late Sereno Watson and others to constitute a new species of Zea, and Watson named it £. catiiia. This plant quickly I'everts to ordinary Corn when grown in the North (see Harsliberger, G. F. 9:522; Contr. Bot. Lab. Univ. Penu. 2:231. Also Bailey, Bull. 49, Cornell Exp. Sta.). Figs. 2774, 2775. Zeu Muys, therefore, may be (1) a true species, of which the wild prototype is unknown; (2) a direct offshoot by domestication of Miichlwna Mexicana; (3) a product of crossing between JSiichlcena Mexicana and some unknown related species; (4) a product of crossing between Uuchlxsna Mexicana and a domesticated race of the same species. Our knowledge is yet insufficient to enable us to offer much more than conjecture on these categories. Maize is remarkably variable, although most of the variations intergrade in different regions and under different conditions. The most extended American study of variation and varieties in Maize has been made by the late Dr. E. Lewis Sturtevant. The summary of his study of varieties is published as Bull. 57, Office of Experiment Stations, U. S. Dept. of Agric. ('Varieties of Corn,' 1899). Sturtevant throws the varieties of Maize into seven 'species groups' or 'agricultural species.' The distinguishing characters of these groups
