BARBADOS FLOWER-FENCE; a genus of plants belonging to the decandra class; and in the natural method ranking under the 33d order, Lomentaceae. See Botany Index.—Of this genus there is only one species, the pulcherrima, which is a native of both Indies, and grows to the height of 10 or 12 feet, producing flowers of a very agreeable odour. In Barbadoes it is planted in hedges to divide the lands, whence it has the name of flower-fence. In the West Indies, its leaves are made use of as a purgative instead of fennel; and in Jamaica it is called senna.
