At a recent meeting of the Academy of Natural Sciences of Philadelphia, Mr. Thomas Meehan remarked that the umbellule of colored flowers in the center of the umbel of the carrot, was represented as usually fertile in Europe and sterile in the United States. He had always found them sterile in the United States until this season, when he discovered that those in the center of the first umbel of the season were fertile. Those in the umbels from lateral shoots were sterile. This had no doubt always been the case, the laterals probably being the only ones examined in former investigations.
