Abstract: An essay on the interrelationship between the anatomy and physiology of the plant, in which it is held that every higher plant is composed essentially of a medulla, the basis for which species have characters in common that unify them as a genus, and a cortex by which nutrition is supplied to the individual. Recognition is given to the presence in a genus of interspecific hybrids. Species are held to have in common certain characteristics of taste and odor. As Frans Stafleu (1921-1997) noted, "This dissertation contained the terms of Linnaeus's theory on the hierarchy of taxa" (Linnaeus and the Linnaeans, p. 145).
