Cluster of female flowers at the top, show- ing the two styles of each pistil, catkins below. calyx, with several lobes, that is, the parts of the calyx are coherent. In the male flowers the calyx is bell-shaped and deeply lobed. The pendent stamens, variable in number, just reach below its margin. The pistillate or female flowers are not borne in catkins, but stand on short stalks, either singly or a few in a cluster. The calyx here is urn-shaped with short lobes. The ovary consists of three united (coherent) carpels, and there are three stigmas. Only one seed is developed in the ovary, and the fruit is an acorn. The numerous scales at the base of the ovary form a scaly involucre, the cup. 511. The beech, chestnut, and oak are members of the oak family. 512.
