Machaeranthera tanacetifolia is a species of flowering plant in the family Asteraceae known by the common names tansyleaf tansyaster and Tahoka daisy.
Description
M. tanacetifolia is an annual or biennial herb growing one or more branching stems up to about 10–40 centimetres (4–15 1⁄2 inches) in height.[1] The multilobed leaves are up to 5–12.5 cm (2–5 in) long.[1] Between May and September,[1] an inflorescence bears one or more flower heads lined with spreading or curling, pointed phyllaries. The head has a center of many yellow disc florets and a fringe of many lavender to purple ray florets each 1 to 2 cm (1⁄3 to 2⁄3 in) long. The fruit is a flat achene about 1 cm long including the pappus.
It is similar to M. parviflora, the flower heads of which are smaller.[1]
