Lemnaceae is a family of flowering plants, also known as the duckweed family, as it contains the duckweeds or water lentils. Since duckweeds are now considered to be a branch of the arum or aroid family (Araceae), the name 'Lemnaceae' is rapidly falling out of use among taxonomists, who treat it as a subfamily called Lemnoideae.

The seeds are highly nitrogenous, and of great food value. They form the principal constituent of the well-known <i>Revalenta arabica</i> of commerce. They consist of -- starch, 50 percent; casein, 24 percent; fat, 2 percent; and water, 14 percent. The dark green German lentils are much more palatable than the reddish-yellow Egyptian variety.

This illustration shows a portion of Lepidodendron. Lepidodendron is the generic name of a large and important group of plants  which flourished principally in the Carboniferous period. The outer surface of the bark is marked by lozenge-shaped, scale-like markings, the leaf-cushions. These are arranged in dense spirals, which wind around the stems. Often, the narrow and pointed leaves are found, still adherent; they may also carry cones <i>(lepidostrobi)</i>, which in form somewhat resemble those of the fir. The branches usually fork repeatedly, and were implanted on a massive stem which had a similar external sculpture. Some of these stems have been seen in the roofs of coal workings with a length of a hundred feet. Their roots are generally known as stigmaria. The Lepidodendra belonged to the Lycopodiaceæ, and have their nearest representatives in the diminutive club-mosses, which they resemble even in their superficial characters.
