He points out that Vienna is too big a city to permit poor addressing.
After some introductory botanical details, Jacquin agrees with Linnaeus in being careful in deciding on new species. However, he sees very many variations in details, and he can not be satisfied with his efforts as a botanist if he does not report and assess these variations.
Additional details are supplied on several plants. More elaborate comments are given on Pistea and Aralia, where he disagrees with Linnaeus’s and Patrick Browne’sBrowne, Patrick (1720-1790).

The species Robinsonia has its name from a Mr RobinsonRobinson, American. Surgeon
