Such are the claffi.cal charaCl:ers of the Tetradynam1a, common to all tHe genera, and, therefore, not neceifary to be rep~ated uncle: every gene:ical name. . The Tetradynamia have fom~ of t.Iiem r:ound1!h pods, with the fiyle adhermg to them, often equal to the pod 1tfelf m length : others of them have very long pods, without this addition of a long ftyle to them. They are hence naturally arranged into two orders; the one ~ontaining thofe with the rou!ldf,ocls, .. under the title of Siliculofre; the other, thofe wtth the long pods, under that o Siliquofre.

It grows wild about the !bores of the Red Sea. When the feeds are ripe, the branches draw up and contraCl:, fo that the whole plant forms a kind of a ball, or globular body, which will expand on laying it a little while in warm water.
