1851 Encycl. Americana II. 211/2 Botany, the science of plants, may be divided into two parts, one of which describes their external appearance and is sometimes called phytography; the other treats of their internal structure and organic action, and may be termed philosophical botany or phytonomy.
1878 Amer. Naturalist 12 728 It is not claimed..that the three mostly parallel series wholly fail to express any general law of the vegetable kingdom, and an attempt will be made..to show that they do express in a partial manner an important truth in phytonomy.
1901 Amer. Anthropologist 3 603 In phytonomy time as causation steps to the front and heredity is the theme, for new individuals are seriated by heredity from generation to generation.
1929 H. E. Bliss Organization Knowl. & Syst. Sci. xvii. 336 Botany he [sc. Ampère (1834)] subdivided into an Elementary branch and Phytognosy, and the latter into Phytonomy and Vegetable Physiology.
