Matricaria chamomilla L.[FNA19, HC, HC2]
wild chamomile, scented mayweed

Publication: Sp. Pl. 2: 891. 1753.

Origin: Introduced from Europe

selected vouchers: WTU

Notes: FNA19: "Although the name Matricaria chamomilla has been considered to be misapplied (e.g., S. Rauschert 1974; A. Cronquist 1994; E. G. Voss 1972–1996, vol. 3), W. L. Applequist (2002) argued convincingly that the name is indeed correctly applied to the taxon described here. Among the North American material, specimens with coronate ray cypselae (var. chamomilla), or wholly without coronas [var. recutita (Linnaeus) Grierson] have been encountered but none with fully coronate cypselae (var. coronata J. Gay ex Boissier), even though synonymy under this name includes M. courrantiana, reported for Texas and New Mexico (specimens not seen). The varieties may not be worth recognizing (Applequist; Q. O. N. Kay 1976) and are not treated formally here."

Rauschert (1974) transferred this from Matricaria to Chamomilla
