Mature achenes still cling to low pussy-toes (Antennaria dimorpha) and cutleaf daisy (Erigeron compositus), although wind disperses seed in lower areas. Other pussy-toes near maturity at low elevations sites. Many early flowering plants develop fruit, but most fruits remain green.

Arnica flowers in the dappled sun, plants burst to bloom, summer’s begun (Arnica sororia, Corral).

Less encountered than other buckwheat species on the ranch, cushion buckwheat thrives on North Ridge. The small grey-green leaves distinguish it from sulphur and golden buckwheat (Eriogonum ovalifolium, North Ridge).

Thread-leaf phacelia flowers develop in helicoid cyme, a typical inflorescence shape for the borage family (Phacelia linearis, Whaley).

Bastard toadflax, like all members of the sandalwood family, parasitize nearby plants. This native plant resembles non-native yellow toadflax in leaf but not in flower (Comandra umbellata, Tongue Creek).

The most common of the eight identified species of pussy-toes on the the ranch, rosy pussytoes grows at all elevations in the grassland, shrubland, and forest (Antennaria rosea, Corral).
