Claim: Chaetadelpha has pointed leaves with cylindrical white or purple flowers and is commonly found in desert regions.
Evidence: Branchlets emerge from the stems and each bears a cylindrical flower which opens at the end into a star-shaped white or pale purple flower with five ray florets. This species is found most often in sand and scrub, particularly in desert regions. Chaetadelpha wheeleri forms a low bush with plentiful erect stems covered in very narrow, long and pointed leaves.
