If, however, intercalary growth be reduced both in the peduncle and tlic pedicels, all the flowers will appear aggregated in a dense head. The axis of the whole inflorescence is then usually enlarged into a general receptacle, upon which numerous flowers are seated. Such an inflorescence is called a Capitulum (Fig. ). It is characteristic of the Compositae. Here again. Fig. 174- Inflorescence of the Vine : a panicle.

(After FiKuicr.) the bracts form a general involucre protecting the whole head, while a bracteole normally subtends each flower borne on the receptacle (Fig. 177). But as these are closely packed, they must mutually protect one another. The bnicteolcs are then superfluous, and are often absent, as they are in the Oxeye Daisy and the Dandelion (Fig. 234, p. 290). Similar capitula are found in the Sheep's Bit (Jasione) among the Campanulaceae, and in the Teasel and Scabious among the Dipsaceae. It is in fact a character recurrent in several distinct famiUes, though it finds its headquarters in the Compositae. Its biological effect is that an inflorescence acts functionally in the s;ime way as a single Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bower, F.
