Milfoil
Including Pelonastes. ORD. Halorageae. A genus of about fifteen species of hardy, half-hardy, or greenhouse, floating, aquatic herbs (rising above the water to flower), found in all parts of the world. Flowers small, disposed in axillary whorls; upper ones male, lower ones female. Leaves finely cut, opposite or verticillate. Very few species are worth growing. They are propagated chiefly by divisions. Three species are represented in the British Flora, but they are not of any value from a horticultural standpoint. M. proserpinacoides (Proserpinaca-like). fl. very minute, l. in whorls of five, very finely pectinated. Brazil, Chili, &c., 1879. A graceful half-hardy aquatic, with an extremely pretty feathery appearance. It requires mud to root in, and is easily increased. The stems are weak, but do not require support, all the pretty points of the shoots growing out of the water, perhaps to a height of 6in. or 8in. SYN. Iierpestes reflexa (of gardens).
