[swbiodiversity.org] Morphology: Centrostegia thurberi is fairly consistent morphologically throughout its range except for individuals in some populations in the mountains of the southern Coast Ranges that tend to have slightly longer and more robust involucres. The name var. macrotheca is available for such plants. (link added by Mary Ann Machi)
