Papilionaceous Flowers.—In the pea and bean tribes the flower has a special form (Figs. 245, 246). The calyx is a shal- low 5-toothed tube. The corolla is composed of four pieces,—the large expanded part at the back, known as the standard or banner; the two hooded side pieces, known as the wings; the single boat-shaped part beneath the wings, known as the keel. The keel is sup- posed to represent two united petals, since the calyx and stamens are in 5's or multiples of 5; moreover, it is of two distinct parts in cassia (Fig. 247) and some other plants of the pea family. Flowers of the pea shape are papilionaceous (Latin papilio, a butterfly). 297. Flowers of the pea and its kind have a peculiar arrangement of stamens. The stamens are 10, of which 9 are united into a tube which incloses the pistil. The tenth stamen lies on the upper edge of the pistil. The remains of these sta- mens are seen in Fig. 206. The sta- mens are said to be diadelphous ("in two brotherhoods") when united into two groups as in this case. Stamens in one group would be called mona- delphous, and this arrangement 24S- Common mallow, a trailing CT plant to which the circle of occurs in some members of the fruits, a, gives the names T . » ., "cheeses" and "shirt button LeguminosaB or pea family. ;.
