Stamens are often united by their filaments, forming a tube, as in the Malva, when they are said to be monadelphous (Fig. 122), or in one brotherhood. In other cases they are united into two sets, when they are said to be diadelphous (Fig. 123), as in the Pea : if into several sets, the term polydelphous is ap- plied (Fig. 124), as in some Hyperica. If the stamens project beyond the corolla, they are said to be exserted, and included when shorter than the corolla. When the stamens all turn to one side of the corolla, they are said to be declinate. When a flower has four stamens, two of which are longer than the other two, they are didynamous (Fig. 125). If there are six, with four the longest, then they are tetradynamous. (Fig. 126.)
