All edges red. = Göran "Georg" Wahlenberg (1780-1851) was a Swedish naturalist and plant geographer who 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). The first plate is a nice profile of the vegetation in the Swiss Alps. Some - mainly marginal - foxing. Front pastedown paper partly missing, a few pages a bit foxed, mostly marginal; title page and dedication page leaves with a restoration in upper margin, but in all a very good copy in a nice contemporary binding.
