They should be planted in soil orpond mud in shallow pots covered with pebbles in the corners of theaquarium. They are mainly propagated by cuttings, and in nature byrhizomes and the peculiar winter buds which remain dormant in coldweather and form new plants in the spring. Botanists are at variance innaming two species of this plant; some designating C. crispus as C. lanceolataand others classing the shorter-leaved of the latter species C. crispus and. AQUATIC PLANTS OF FRESHWATKR assigning the long-leaved varieties ot C. lanceolala with less crinkled leavesto C. gramirice. This is not essential to the aquariist. The author illus-trates the species as he recognizes them. It is a variable genus some-times difficult of identification. WATERCRESSES The Family of Roripa or Watercresses contain about 25 species,most abundant in the North temperate zone, of which eleven are native toNorth America. Of these the species generally distributed in the East-ern and Middle States are:— Roripa palustris (Linn.) Nasturtium terrestre(A. Br.) or Marsh or YellowWatercress, an erect, branching, glabrous plant having the lower leavespetioled and the upper leaves nearly sessile, with yellow flowers andlinear-oblong fruit pods.
