A study describes the histomorphology of the corpora cardiaca in female S. pandurus obtained from Calotropis procera in Bihar, India. Two types of cells are present: chromophilic and chromophobic cells. The former are bound anteriorly and mesially close to the aorta, while the latter are located posteriorly and laterally. The part nearer the brain acts as a storage organ for neurosecretory materials, while the distal part is secretory in nature.
