Large leaved umbrella tree (Magnolia macrophylla)
"My father, in his “Flora Boreali-Americana,” as well as many succeeding botanists, designates it by the name of Magnolia macrophylla, Large-leaved Umbrella Tree, while in the catalogues of gardeners, and sometimes in those of botanists, it is denominated Magnolia Michauxii. I have thought proper to drop this specific name, however honorable to my father, and to retain the one which he himself had established. […] The flowers diffuse a fragrant odor, and their beauty is heightened by the luxuriant foliage which surrounds them."
This illustration and the description are from volume two of "The North American sylva ; or, A description of the forest trees of the United States, Canada, and Nova Scotia ... to which is added a description of the most useful of the European forest trees," by François André Michaux, 1770-1855 (Published by D. Rice and A. N. Hart, 1859-1865)
