COMPOSITJE. Flowers small, in a head on a eomtnon receptacle surrounded by an involucre of one or more rows of bracts; stamens 5, inserted on the corolla tube, the anthers united {syngenesious); ovary 1-oelled forming an achene in fruit; style cleft at the apex with 2 usually recurved stigmas, or frequently undivided in sterile flowers ; calyx represented by a number of bristles or scales (pappus), or absent; corolla tubular or strap-shaped [ligulate), when the former usually 5-toothed. When both tubular and ligulate corollas are present in the same head the former are in the centre (-disk), and the latter {ray-flowers) are around the margin. Such a head is called radiate, while if only tubular corolla are present, the head is said to be dis- coid. A very large family divided by the kinds of corollas present in the heads into two series, the tubuUflorce and the ligulifl, Fig. 80. - Section through a typical radiate head.
