Varies infinitely in the size of flowers, smoothness of calyx, and looseness or com- 
pactness of inflorescence, the intergrading forms blending almost imperceptibly 
with the varietal forms which have been described. Forms with large flowers in 
looser cymes, the calyx and corolla less papillose, distinguished as C. pulcherrima 
and C. neuropetala, occur in damp situations; in the dry sands the flowers are smaller, 
strongly verrucose papillose, the lobes of the corolla with a strongly intlexed point, 
and the flowers in dense clusters, such forms responding to C. indecora Engelm. 
Type locality (fide Engelmann): On the Rio Grande. ( Berlandier.)
