He subsequently visited Willdenow without an appointment and found him to be a kindred soul only four years older and in three weeks he became an enthusiastic botanist. In his 1792 book, ''Grundriss der Kräuterkunde'' or ''Geschichte der Pflanzen'' Willdenow came up with an idea to explain restricted plant distributions. Willdenow suggested that it was based on past history with mountains surrounded by seas with different sets of plants initially restricted to the peaks which then spread downward and out with receding sea levels. This would fit with the Biblical notion of floods. This was contrary to earlier assertions by
