Species Zornia pratensis

For Johannes Zorn (1739–1799), German pharmacist and botanist, who travelled all over Europe searching for medicinal plants. After studying pharmacy, he became an apothecary in his home town of Kempten, Bavaria. In Nurnberg, between 1779 and 1784, he published Icones Plantarum Medicinalium (Images of Medicinal Plants), illustrated with 500 hand-coloured engravings, expanded to 600 engravings in his second edition (1799). He was also passionate about the plants of the New World, and published a flora of America in 1786 called Drey Hundert Auserlesene Amerikanische Gewachse (300 Select American Plants), based on a very rare book (there were only three coloured copies) by NJ Jacquin, Selectarum Stirpium Americanarum Historia (1763).
