THE FLOWER. 45 stamen directly in front of or within a petal; and the parts are said to be opposite (Fig. 99). But in the other case the petals are in frout of or within the spaces between, that is, alternate A/^%^ Avith the sepals, and the stamens alternate with the petals; then the parts of the flower are said to be "^ ^°'^ alternate (Fig. 100). When the parts of the flower, espe- cially of the calyx and corolla, are each three in number, the flower is said to be three-parted ; and it is generally found that three-parted flowers are borne on plants which have parellel-veined leaves. If the parts are in 4's or 5's, the flowers are respect- ively four or five-parted ; such flowers gen- erally accompany netted-veined leaves. ''* 55- When the sepals are free, or dis- I pi6«, tinct from one another, the calyx is said 101 to be polysepalous (Gr. polus, many); and when the petals are free, the corolla is polypetalous (Fig. 101). The sepals may be united edge to edge, so that only their upper ends are free, by which the number form- ing the cup or calyx may be deter- mined. The calyx in such case is said to bs monosepalous (Gr. monos, one), or gamosepalous (Gr. gamos, union). When the petals are united, the corolla is monopeta- lous, or gamopetalous (Fig. 102). This union of similar parts or cohe- sion, as it is called, gives rise to a Fig. 99. Diagram of a flower with parts opposite. Fig. 100. Diagram of a flower with parts alternate. Fig. 101.
