 Herbaceous, stemless, or caulescent plants, with broad fleshy leaves, approaching very nearly to those of 

 Dicotyledons. Their flowers are enclosed within a spatha, and are embedded on a simple cylindrical spadix. 

 Some are natives of Europe and of similar latitudes, but the greater number inhabit the tropics, where they 

 often climb by their rooting stems to the tops of lofty trees. They have thick fleshy roots, which, when fresh, 

 contain an acrid stimulating principle, which is so volatile that it passes off freely upon the application of 

 heat ; whence the roasted roots of many species are among the most common articles of negro food. The 

 leaves of A\um seguinum are so paralysing, that if chewed they deprive one of the power of utterance ; 

 whence in the West Indies it is called the dumb cane ; the leaves of Calla pertusa are acrid ; fresh gathered, 

 and applied all over the surface of the body, they produce a slight inflammation and blistering, and are used 

 in Demerara by the natives in dropsical cases. The root of JVum triphyllum, boiled in milk, has been found 

 efficacious in consumption. The flowers of many species are highly fetid. Division and offsets.

 With these the Vasculares and Monocotyl<?dones terminate : it has long been apparent that we have been 

 descending in the scale of vegetation , and, hence, the last order exhibited a structure the most simple of all 

 vascular plants. In the present order, Zostera and Ruppia are so closely allied to A'lgze, that they may be 

 mistaken for them. Offsets and division.

 Inconspicuous, rigid, worthless weeds, for the most part ; Xyris, Philydrum, and Narthecium which have 

 pretty yellow flowers, if belonging to the order, being exceptions. They clothe barren ground in most parts of 

 the world, and are the first approach to the formation of a regular perianthium, as we ascend in the scale of 

 vegetation. Xerotes has the habit of a low palm. Division and seeds.

The sedges, as these may be called in English, differ from grasses not only in their comparative worthless- 

 ness, and the different developement of the parts of fructification, but also in the sheath, at the base of the 

 leaves, being closed up, not slit. As objects of ornament they are of no value, and as subjects of agricultural 

 interest of but little; they are, moreover, of little utility to man. They are chiefly valuable for covering, with 

 the appearance of herbage, waste and barren marshy or sandy tracts, in which little else will thrive. The 

 roots of Carex arenaria, disticha, and hirta, possess diaphoretic and emulcent properties, whence they are 

 sometimes called German sarsaparilla. Some of the Scirpuses and Cyperuses have eatable nutty roots ; the 

 stems of Scirpus lacustris, Eleocharis palustris, Cyperus t£xtilis, and others, are manufactured into mats and 

 the bottoms of chairs ; the roots of Cyperus esculentus abound in oil, a very unusual circumstance ; the papyrus 

 of the ancients was manufactured from the stem of Papyrus antiqudrum j finally, the roots of Cyperus 16ngus> 

 odoratus, and others, are fragrant. Division and seeds.
