Diagnostic Characteristics:
The characters that distinguish Eurybia (Aster) saxacastelli are as follows: Coarsely toothed leaves distributed on the stem (none basal) with dimensions generally 9-14 x 4-6 cm, and petiole winged or the leaf tapering to to a narrow sessile base (not clasping the stem). The stem is glabrous except possibly some hairs beneath the flowering heads. Achenes are pubescent. The river bar and bank habitat also helps to distinguish it.

Management:
Avoid degradation of water quality, hydrology or changes in natural river flow. Disturbance of areas surrounding this habitat such as ATV trails, timber removal or any activity that results in increased erosion and weed invasion will be detrimental. Exotic pest plants are a threat to this species and should be removed. Avoid creating access to the site through trail or road construction.
