Monadelphous (i. e. in one brotherhood), when the filaments are united all into one set or tube, as in Lobelia (Fig. 184/), and the Mallow Family (Fig. 185) ; also in Passion-flowers and Lupines (Fig. 187). Diadelphous (in two brotherhoods), when the filaments are united in two sets. Fig. 186 shows this in the Pea, and the like, where nine stamens are combined in one set and one stamen is left for the other. Triadeiphous (in three brotherhoods), when the filaments are united or collected in three sets, as in the Common St. John's-wort or Hy- pericum (Fig. 297); and Polyadelphous (in many brotherhoods), when combined in more than three sets, as in some St. Jolm's-worts. 215. Pistils United are very common. Two, three, lour, or more grow together at the time of their formation, and make a Compound Pistil. Indeed, wherever there 'i ; "tie pistil to a flower, it is much oftener a compound pistil than a simple one Bu , of course, when the pistils of a flower are more than one, they are ah Z'ple Pistils may be united in every degree, and by their ovanes only, by then ^ only (as they are slightly in Prickly-Ash), or even by their stigmas only (as nMiS weeds), or by all three.
