systematic botanists, so named by Linnæus, who have arranged all vegetables from the different species, structure, and other circumstances, of the calyx or flower-cup. The only systems of this kind are the Character Plantarum Novus, a posthumous work of Magnolius, professor of botany at Montpelier, published in 1720; and Linnæus's Methodus Calycina, published in his Classes Plantarum, at Leyden, in 1738.
