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. Gardening. ZEA from the Teosinte (Enchlcpna Mexicana), a fodder grass tliat 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 affinity of the two species. Plants of this hybrid were thought by the late Sereno Watson and others to constitute a new- species of Zea, and Watson named it Z. eattinu. This plant quickly reverts to ordinary Corn when grown in the North (see Harshberger, G. F. 9:522; Contr. Bot. Lab. Univ. Penn. 2:231. Also Bailey, Bull. 49, Cornell Exp. Sta.). Figs. 2774, 2775.

Our knowlecim' i^ yif iii^nfKi-ieiit to 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 summarv of his study of varieties is published as Bull. 57, Office of Experiment Stations, U. 8. Dept. of Agrie. ("Varieties of Corn," 1899). Sturtevant throws the varieties of Maize into seven "^y,;-!.-^ groups" or "agricultural ; The ili^i inLMii-lniif,' characters of these groups are fouii'lid â ;, tin k. rnels. Aside from
