ErameriaceSB (Rhatany Family) consists of the genus Krameria only, which has ordinarily been annexed to the Polyga- lacea3; but the position of the parts of the flower is more like that of the Leguminosje, having the odd sepal inferior, a simple unilocu- lar pistil, and an exalbuminous seed. In fact it is technically distin- guishable from the latter chiefly by the hypogynous stamens and the want of stipules. The roots contain a red coloring matter, and are astringent without bitterness. Ehatany-root, used to adulterate port- wine, and as an ingredient in tooth-powders, &c., is the produce of K. triandra of Peru. That of our own Southern species possesses the same 804. Ord.
