Two species, Salvinia nutans, native to the Southern and Southwestern States, and the larger tropical S. brasiliensis, are to be obtained of florists. Fig. 136. The leaves of the native species are heartshaped, and of a bright, beautiful green color, and covered with hairlike bristles, the under side of the leaf being a purplish-red. The larger, more circular leaves of the exotic species are pale golden yellow with pea-green tints and a bright-green border; and are more rounded with a depressed centre which gives the leaf a heartshaped appearance. The leaves grow in rows along a fine threadlike stem, ^,^ , „ , . „ , . and in the moist atmosphere of the greenhouse FIG. 136. Salvinia, Sal-vinta natans, _ _ '^ _ _ ° _ develop and increase with increditable rapidity, but in the household aquarium soon diminish in size and rarely survive the winter. Goldfishes eat the roots, which also tends to check the growth. It is the handsomest of the floating aquarium plants but does not serve as an oxygenator. Two new species have recently be- come known, S. auriculata from South America, and S. elegans from Mexico. TRIANEA This sub-tropical floating water plant, Trianea bogotensis. Fig. 137, with its heartshaped, slightly roughened and waxlike green leaves, is an attractive floating plant, which develops with remarkable rapidity in the moist atmosphere of the greenhouse, but dwindles in size of leaf and loses vigor in the household aquarium. The pendant roots harbor infusoria and entomostraca and are eaten by the fishes. It makes a fine appearance in the aquarium, but will not serve as an oxygenator. The leaves develop in the centre of the clusters and t
