Notes
Move to CRPR 2 or 4? Location and rarity information needed. Many herbarium specimens of T. canescens not determined to variety; annotations needed, yet difficult to distinguish between varieties in dried material; needs study. Many occurrences historical; need field surveys. Known only from the Sonoran Desert. Threatened by solar and wind energy development. Possibly threatened by military activities and vehicles. See Journal of the Arnold Arboretum 20(3):379 (1939) for original description, and Sida 6(3):235-240 (1976) for taxonomic treatment.
