Diagnostic Characteristics:
This species has pubescent stems and the calyx is villous (has long hairs). The flowers are usually purple which distinguishes it from Dalea candida . In general this species has a dense head of flowers, similar to a small cone, and the leaves are small and odd pinnate (divided into leaflets with an additional terminal leaflet).

Woody plant invasion may need to be controlled using periodic prescribed fire, mowing or other means. Timber removal may be beneficial. Hand removal of trees in the vicinity is needed to maintain the open character of the habitat for this species. Soil disturbance such as ATV trails or 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.
