An important well-illustrated work with excellent illustrations including those of a surprising number of new species. Friedrich Adolph Roemer (1809-1869) was a German botanist and geologist. 'In 1845 he became professor of mineralogy and geology at Clausthal, and in 1862 named director of the School of Mines' (Wikipedia). Age-toning and some mostly marginal foxing throughout due to the quality of the paper. Rare. We have not seen another copy on the market this century.
