The photo above shows a close-up of the open
inflorescence of Brewer's cinquefoil as seen on Mt. Adams..........July
16, 2005. The long scapes at first spread outwards from the tuft of woolly basal
leaves but then typically ascend or become erect from mid-scape. Note the leafy
bracts at the base of the inflorescence.

The photo above shows the pinnately comound
leaf of Brewer's cinquefoil. The leaflets are woolly-haired below, and often
so above. The 9-11 leaflets are greater than 1.5 cm wide and 1-2 cm long, and
deeply cleft as seen in the photo. Note also the photos of older plants, taken
later in the season below.
