Salix fragilis along the Gallagator Linear trail, just south of the Peets Hill parking lot, Bozeman, Montana, remains common along Spring Creek riparian corridor. This exotic willow isn't replacing native diversity given that many other native species co-exist with fragile willow. Fragile willow is an apt common name given how winter storms often break branches of varying diameters.

Lotus corniculatus grows commonly along roadsides and trailsides in the Bozeman area and continues to grow, flower, and fruit into late summer and early fall. The umbellate inflorescence bearing flowers with bright yellow petals and the trifoliolate leaf with leaf-like stipules (superficially rendering a five-foliolate leaf) are diagnostic of this species. This site lies south of College Avenue between 11th and 12th Streets, Bozeman, Montana.
