Collomia, sometimes called "mountain trumpets", has 15 species. The genus derives its name from the greek word "Kolla", which means "gluton", in reference to the sticky nature of the seeds when wet. Thomas Nuttall named the genus in 1818 based on a plant he collected in 1811 near the junction of the Cheyenne and Missouri Rivers (in present day South Dakota, U.S.A.). The first species belonging to this genus to be named, however, was collected in the late 1700's in Chile, and was considered a member of the genus Phlox. Collomia species vary from obscure to showy; all 15 species share a distinct odor that, while not offensive, isn't really attractive either.
