| Identification | Corn Chamomile looks like a small version of Oxeye Daisy (Leucanthemum vulgare), but the Chamomile leaves are pinnately dissected into triangular segments. The flower heads -- noticeably smaller than those of Oxeye Daisy -- are held erect above the leaves; the rays are white and about 10-15 mm long, the disc yellow and rather flat in bloom but dome-shaped in fruit. Stinking Chamomile (A. cotula) is very similar, but it has the disk strongly domed when in full flower, and it has sterile ray flowers (as opposed to fertile ones in A. arvensis). Other characters are that this species is pubescent overall and is odorless; the other (A. cotula) is nearly glabrous overall and is ill-scented. | |
