9. Amphiachyris (broomweed)
(Lane, 1979)
Two species, U.S.
The decision by
Lane (1979, 1982) to accept the segregation of the genus Amphiachyris
from the closely related Gutierrezia based upon a suite of morphological
and cytological features was corroborated by Suh and Simpson’s (1990)
subsequent molecular phylogenetic analysis.
