The new and curious aquatic plant from Madagascar, called the Lattice Plant ( Ouvi-randra fenestratis), must be placed among the most remarkable of our recent botanical acquisitions. Its existence had been for some time known to botanists through a few dried leaves sent from Madagascar by a tra~ Teller, who was unable to transmit living specimens of the curiosity he had discovered; and it was not until within the last few months that this desirable object could be attained, when several living plants were brought over to England from the above-mentioned country, by the Rev. Mr. Ellis, a missionary. This gentleman shortly transferred the whole stock to Messrs, Veitch, of the Exotic Nursery, King's-road, Chelsea, by whose kind permission the accompanying sketch was made from the specimens in their possession. The plants under their hands are thriving extremely well, and will be found worthy of a visit from the curious in these matters.

The interest of this plant lies in the extraordinary structure of the leaves, which, unlike those of any other known plant, are made up of the ribs and cross-veins only; the interstices, which in other leaves are filled up with cellular tissue, being here left almost entirely open, so as to give the leaf the appearance of a piece of curious net or lattice work, from which is derived its com-mon name - the Lattice Plant.

That the beauty of this unique vegetable curiosity may be thoroughly appreciated, it mast be seen growing in its natural situation - submersed in water, with every motion of which the lace-like leaves take the most graceful, undulating curves. The plants at Chelsea Nursery are placed in broad glass pans, which allow the structure and movement of the leaves to be perfectly visible by the light transmitted through the sides. The temperature required is about 75 degrees.

As far as can be judged from so short an acquaintance with its habits, little difficulty is to be anticipated in the cultivation of this plant, which will probably be, ere long, as extensively distributed among the collections of this country as, from its great interest and beauty, it fully deserves to be. - Illustrated News.
