This order is divided into 3 suborders, TubuliflorsE, Liguliflorse, and Labiatiflorffl, only the 2 first of which are represented in the JSTorthern States. In Tubu- liflora! either all the flowers, or the central flowers, are tubular. This structure is exemplified in the Thistle, one species of which {Olrsium lanceolatwn), is seen in fig. 17, where the flowers are all tubular. In the same figure is shown one of the separate flowers, -or florets, with its pappus surrounding the tubular 5-cleft corolla, that incloses the tube of 5 united anthers, through which projects the bifid style. In fig. 18 {Aster patens), we have au illustration of the form in which ouly the central florets are tubular, those of the ray being ligulate, or strap-shaped. The two kinds of florets in this species are seen in the same figure. In the Ambrosia artemuice- folia, fig. 19, we have an example of this sub-order in a reduced form, with inoncecious Jiowers destitute of corollas. In the second suborder, Liguliflorse, the flowers are aU ligulate, as in the Dan delion, fig. Fig. 18. This is a vast order, much larger than any other in the Natural System, and comprehending about 9000 species. But their importance hardly corresponds with their abundance. Tho whole order is pervaded by a bitter astringent principle, which is sometimes tonic, as in the Boneset (Eupaioi'ium perfolia- turn), and the Camomile. In others it is aromatic, as in Artemisia (Wunn- wood), or even acrid, as in Maruta {May-toeed). Tho Boneset also has emetic.
