Saporta, Marquis de, (1823-95): devoted himself to the study of fossil
plants, and by his untiring energy and broad scientific treatment of the
subject he will always rank as one of the pioneers of Vegetable
Palaeontology. In addition to many important monographs on Tertiary and
Jurassic floras, he published several books and papers in which Darwin's
views are applied to the investigation of the records of plant-life
furnished by rocks of all ages. ("Le Marquis G. de Saporta, sa Vie et
