Besides these, the pretty yellow flowers of Villarsia indica, the red blos- soms of Euryale ferox, the yellow flowery Jussieua natans, and the white Alisma cordifolia, make a group of great beauty. The leaves alone of the Nymphseas make them well worthy of cultivation. For the greenhouse aquarium we have an equally extensive selection. Two species of water- lilies, Nymphsea reniformis, and odorata, both with white flowers; Limnocharis Plu- mierii, and L. Humboldtii, with pretty pale yellow blossoms. The remarkable genus Sarracenia, with their pitcher - shaped leaves, grow best with their roots in shallow water. Jussieua grandiflora, Alisma par- nassifolia, Frontium aquaticum, Hypoxis aquatica, Byblis liniflora, (blue,) Drosera binata, Menyanthes americana, Villarsia lacunosa, and ovata, cum multis aliis, are all beautiful ornaments to the greenhouse aquarium. Few who have not seen a well- arranged aquarium can imagine anything so beautiful as one when in ; In regard to the structures best adapted for this purpose, we may observe that, as aquatics require the greatest possible de- gree of light, a house that presents the largest surface of glass must be looked upon as the most proper; nor must they, for the above reason, be placed too far from the glass. A house of the span- roofed form is the most suitable, so far as economy is concerned, as it admits of various heights, which is a positive condi- tion to be observed; but, unfortunately, in such houses the walk is in the middle, and, consequently, the tallest-growing plants
