These wildflowers were previously included in the caper family (Capparaceae). As far as I can tell, the family hasn't been around long enough to pick up an English name.

Rocky Mountain Beeplant (Peritoma serrulata)
This plant was formerly known as Cleome serrulata, and is listed as such in many guides. For years I knew it simply as beeweed. One photo shows how the individual flower has four petals. The boiled-down sap from this plant may have been used to create the carbon-based black paint on some Ancestral Puebloan pots.
Red-Whisker Clammyweed (Polanisia dodecandra)
