‎---- EDITION ORIGINALE ---- BON EXEMPLAIRE NON COUPÉ ---- "In his work in general Saporta, french paleobotanist (1823/1896), was a patient and meticulous researcher who attempted both to give a precise description of a species and to relate it to historical developments so as to clarify its origin... He emphasized the difficulty of determining species and advised caution ; while he has been accused of erroneously increasing the number of species, such accusations are unjustified, and recent studies have frequently served to confirm his general views... Saporta's scientific reputation was widespread...". (DSB XII pp. 104/105)**4659/A7AR‎
