Silvery lupine growing in the subalpine below Saddle Peak and along the Middle Cottonwood Creek trail, west side of the Bridger Range, Gallatin County, Montana. Silvery lupine is diagnosed by a glabrous banner petal, glabrate to sericeous leaves and stems, and flowering early summer. Flowering at this site during early July at subalpine elevations contrasts to late May and early June flowering at lower elevations in the foothills of the Bridger Range.

Littleflower alumroot growing in mountain big sagebrush steppe of Yellowstone National Park about 9 miles east of Mammoth and north of the Grand Loop Road, Park County, Wyoming. In early season condition, littleflower alumroot is distinguished by ovate to sometimes reniform (kidney-shaped) leaves with 5-7 lobes that are each shallowly lobed or crennate. The upper leaf surface is glabrous and the lower surface glandular. When mature, the flowers are small for a Heuchera, less than 4 mm long.

A close inspection of all fruits on 2 spikes showed all to have 3-parted walls. Not as hairy as they maybe could be, but definitely hairy. Huge dark green leaves, white chalky bark, and riparian habit are all supporting features. All material in hand was taken from 25' up.

Erysimum capitatum growing in postfire Douglas Fir forest (with some Rocky Mountain juniper and limber pine) at the south end of the Bridger Range, Gallatin County, Montana. The burn occurred September 2020. Plants in flower were photographed June 2023 and the plant in fruit during July 2022. The erect ascending fruits and dolabriform hairs uniformly scattered along the stem distinguish this species from Erysimum asperum (western wallflower).
