The main paper is a detailed study of the flora of the region north of Paris, and comes with a fine, large map. The author, count Léonce de Lamberteye (1810-1877), put emphasis on the relationship between the botany and the geology, topography and soils of the region. In the rear (pp. 194-203) is a short chapter, titled Description de l'Erysimum cheiriflorum extraite de la monographie inédite du genre Erysimum par M. Gay, written in Latin. The commentary paper by the French lawyer and botanist Stanislas Nicolas Chaâles Des Etangs (1801-1876), here as an offprint of the M émoires de la Société d'Agriculture, des Sciences, Arts et Belles-Lettres du département de l'Aube is listed and described as a second work, but actually bound in front of the main work. Short tear into the map near the adhesion point. Some scattered foxing; fold in first blank with some soiling, but generally clean and a very good copy indeed. Rare. Especially with the large map.
