تعريف asa gray في الإنجليزية الإنجليزية القاموس.

born Nov. 18, 1810, Sauquoit, N.Y., U.S. died Jan. 30, 1888, Cambridge, Mass. U.S. botanist. He received a medical degree from Fairfield Medical School, where he spent his spare time studying plant specimens. He collaborated with John Torrey (1796-1873) on Flora of North America (1838-43) and in 1842 joined the faculty at Harvard University, where he would teach until 1873. His donation of his thousands of books and plant specimens established Harvard's botany department. Gray was largely responsible for the unification of the taxonomic knowledge of the North American flora; his most widely used book, commonly called Gray's Manual (1848), remains a standard work. He was the chief early American supporter of the theories of Charles Darwin
