  • Move to CRPR 1B? Herbarium material indicates taxon is conspecific with C. scoparium, but field studies reveal differences; definitive taxonomic study needed. Threatened by mining, development, and vehicles. Possibly threatened by competition. A synonym of Helianthemum scoparium in TJM (1993) and TJM 2. See MadroƱo 5:81 (1939) for original description and Phytologia 93(2):271 (2011) for revised nomenclature.

      * Presumed extirpated
      ? Uncertain about distribution or identity
      ?* Uncertain about distribution, but presumed extirpated if once present
      (?) Occurrence confirmed, but possibly extirpated
      Species may be present in other areas where conditions are favorable. This data should NOT be substituted for pre-project review or for on-site surveys.
