"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). The first plate is a nice profile of the vegetation in the Swiss Alps.

Original blind front wrapper bound in. Cancelled library stamp of the Conservatoire Botanique de Geneve on the title page; some light foxing, otherwise a very good copy. Stafleu and Cowan, 16519.
