On British wild flowers considered in relation to insects
Sir John Lubbock's 1890 Macmillan study of British wild flowers, written for general naturalist readers, explains how flowers depend on insects for pollination. The pictures are fine pen-and-ink botanical drawings of flower parts, with labelled anthers, stigmas and petals, sectioned at magnification. A designer could take their precise line work and clear labelling as a model for scientific diagrams.
