Order CLXXV. CYPERACEiE. 
The sedges, as these may be ca led in English, differ from grasses not only in their comparative worthlcss- 
ness, and the different developement of the i)arts 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 a{)pearance of herbage, waste, and barren, marshy, or sandy tracts, in which little else will thrive. The 
roots of Carex arenaria, d'lsticha, and hirta, possess diaphoretic and demulcent properties, whence they are 
sometimes called German sarsaparilla. Some of the Scirpuses and Cyp^ruses have eatable nutty roots ; the 
stems of Scirpus lacustris, Eleocharis palustris, Cyperus textiles, and others, are manufactured into mats and 
the bottoms of chairs ; the roots of Cyperus escul^ntus abound in oil, a very unusual circumstance ; the 
papyrus of the ancients was manufactured from the stem of Cyperus papyrus j finally, the roots of Cyperus 
longus, odoratus, and others, are fragrant.

Order CLXXVI. AROIDEiE. 
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 imbedded 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' rum seguinum are so paralyzing, that if chewed they deprive one of the power of utterance; 
whence in the West Indies it is called the dumb cane i the leaves of Drac6ntium pertusumare 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 A'rum triphyllum, boiled in milk, has 
been found efficacious in consumi)tion. The flowers of many species are highly fetid. Typhineje, or bull- 
rushes are very like Cyperaceee in habit. Pistiaceas are floating plants, in which the organs of fructification 
are reduced to the very simplest state. Juncagineae are obscure marsh or river plants.
