BASTARD DOGSBANE; a genus of the digynia order, belonging to the pentandria clas of plants. There are six species, of which the following are the most remarkable. 1. The acutum, commonly called Montpelier scammony; and, 2. The montpeliacum, or round-leaved Montpelier (camomile). They abound with a milky juice like the spurge, which flows out wherever they are broken; and this milky juice when concreted, has frequently been sold for scammony. These plants propagate so fast by their creeping roots, that few people care to admit them into gardens.
