In an inflorescence, when each individual flower has a separate peduncle, this separate peduncle is called a Pedicel. When a pedicel has a bract, this bract is called a Braeteole. Bracts around a solitary flower, or around an inflorescence, form an Involucre; when around a single flower in a cluster (Teasel, Fig. 105), or around a secondary cluster (Parsley, Fig. 139), they form, an Involucel.

The rust called Pucoinia graminis, growing on wheat, has its cluster-cup stage on the leaves of barberry in June. The spores from the cluster-cups are carried by the wind to the wheat, where they germi- nate and in a few days produce the red rust. A little later the black spores appear, produced by the same myce- lium. This growth is chiefly upon the stems and sheaths.. Fig. 181. A Cluster-Cup of

These spores, as their name implies, are arranged in clusters in cup- like cavities of the leaf (Fig. 228), which are produced by their growth. On exam- ining thin sections of the leaf carefully, we see that the cluster-cup spores are in long chains borne on short stalks (Fig. 229). On the upper surface of the leaf occur smaller cavities filled with smaller slender spore-bearing stalks; their function
