Machaeranthera
''Machaeranthera'' is a genus of North American flowering plants in the family Asteraceae which are known by the common name tansyaster. Tansyasters are variable in appearance. Some are small, singular wildflowers, while others are sprawling shrubs. Several species easily hybridize with each other, as well, making identification difficult. In general, members of the genus may be identified by the sharp-pointed, dagger-shaped anthers in the disc florets at the center of the flower. The flower heads are usually daisylike, and are usually a shade of purple or blue, but may be pink, yellow, or white. Tansyasters are native to western North America. The genus ''Machaeranthera'' is distinguished from the genus '' Dieteria'' by having once- or twice-pinnate leaves, whereas ''Dieteria'' has entire to toothed leaves.Mojave Desert Wildflowers, Pam MacKay, 2nd Ed. 2013, p. 39 ''Machaeranthera'' means "swordlike anthers The stamen (plural ''stamina'' or ''stamens'') is the pollen-produ ...

Astereae
Astereae is a tribe of plants in the family Asteraceae that includes annuals, biennials, perennials, subshrubs, shrubs, and trees. They are found primarily in temperate regions of the world. Plants within the tribe are present nearly worldwide divided into over 250 genera and more than 3,100 species, making it the second-largest tribe in the family behind Senecioneae. The taxonomy of the tribe Astereae has been dramatically changed after both morphologic and molecular evidence suggested that large genera such as '' Aster'', as well as many others, needed to be separated into several genera or shifted to better reflect the plants' relationships. A paper by R. D. Noyes and L. H. Rieseberg showed that most of the genera within the tribe in North America actually belong to a single clade, meaning they have a common ancestor. This is referred to as the North American clade. Guy L. Nesom and Harold E. Robinson have been involved in the recent work and are continuing to re-categoris ...
