词汇 | rudbeckia |
词源 | Rudbeckia. Under adam’s apple we mentioned the Swedish professor who tried to prove that the site of the Garden of Eden was located in the Land of the Midnight Sun. The profes- sor, Olaf Rudbeck (1630–1702), also claimed in his book At- lantikan that Sweden had been the locale of Plato’s Atlantis. But he was otherwise a fine scientist, discovering the lymphatic system and making various botanical contributions. Linnaeus so admired the Rudbeck family that he named the North American coneflower after both Professor Rudbeck and his son, the junior Professor Rudbeck being a contemporary of Linnaeus. The Rudbeckia genus, some 25 species, includes the popular black-eyed Susan and golden glow. Plants in the genus are herbs, usually having yellow rays, and can be annual or perennial. |
