‎First edition of Warming’s doctoral dissertation, a landmark study in plant morphology and organogenesis. Here Warming investigates the cyathium (the characteristic cup-shaped structure) of the Euphorbia genus, seeking to determine whether it should be classified as a single flower or as an inflorescence. Warming’s work provided an important contribution to the understanding of floral structures in angiosperms. Johannes Eugenius Warming (1841–1924), commonly known as Eugen Warming, was a pioneering Danish botanist widely recognized as one of the founding figures of modern ecology. He authored the first textbook on plant ecology in 1895, introduced the first university course in the subject, and helped define the scope and content of ecological science. In 1975, ecologist R. J. Goodland asserted: “If one individual can be singled out to be honoured as the founder of ecology, Warming should gain precedence” (""The Tropical Origin of Ecology: Eugen Warming's Jubilee""). Warming wrote a number of textbooks on botany, plant geography and ecology, which were translated to several languages and were immensely influential at their time and later. Most important were “Plantesamfund and Haandbog i den systematiske Botanik”.‎
