Chamomile (scented mayweed)
Matricaria recutita

M. chamomilla has a branched, erect and smooth stem, which grows to a height of 15–60 cm (6-24inches). The long and narrow leaves are bipinnate or tripinnate.

The flowers are borne in paniculate flower heads (capitula). The white ray florets are furnished with a ligule, while the disc florets are yellow. The hollow receptacle is swollen and lacks scales. This property distinguishes German chamomile from corn chamomile (Anthemis arvensis), which has a receptacle with scales. The flowers bloom in early to midsummer, and have a strong, aromatic smell.
