Wahlenberg (1780-1851, Swedish botanist and plant geographer) greatly promoted floristic and systematic research in Sweden. "In 1812-14 Wahlenberg travelled in Switzerland ... His researches in the Swiss alps resulted in the book 'De Vegetatione et Climate in Helvetia ...', in which he gives an account of the plant regions and their designations, the tree limits, and the lower and upper limits of the various plants, comparing also the vegetation in northern Switzerland with that of Lapland" (Fries. Short history of Botany in Sweden, p. 69).
A good example of this very rare work on Swiss plant ecology. Uncut. Wrappers worn. Light age spotting. Trace of old library stamp to title and one other leaf.
