Heterotoma
(from heteros, variable, and tome, a cut; corolla unequally cut). ORD. Campanulaceae. A genus containing four species of annual or perennial herbs, natives of Mexico. Flowers pedunculate, in terminal racemes; corolla blue or golden. Leaves alternate, petiolate. The species here described-perhaps the only one yet in general cultivation-is a very ornamental greenhouse or half-hardy plant. For culture, see half-hardy species of Lobelia.
