Hornbeam Hornbeam Hornbeams are hardwood trees in the flowering plant genus "Carpinus" in the birch family Betulaceae. The 30–40 species occur across much of the temperate regions of the Northern Hemisphere. The common English name "hornbeam" derives from the hardness of the woods (likened to "horn") and the Old English "beam" "tree" (cognate with German "Baum"). The "American hornbeam" is also occasionally known as "blue-beech", "ironwood", or "musclewood", the first from the resemblance of the bark to that of the American beech "Fagus grandifolia", the other two from the hardness of the wood and the muscular appearance of the trunk, respectively.
Jesuit's bark Jesuit's bark Jesuit's Bark, also known as cinchona bark, as Peruvian Bark, and as China Bark, is a former name of the most celebrated specific remedy for all forms of malaria. It is so named because it was obtained from the bark of several species of the genus "Cinchona", of the Rubiaceae family, that have been discovered at different times and are indigenous in the Western Andes of South America and were first described and introduced by Jesuit priests who did missionary work in Peru. Other terms referring to this preparation and its source were "Jesuit's Tree", "Jesuit's Powder" and
