The digestive fluid of Dionaea muscipula has been studied with respect to its protein content as a function of time after entrapment of protein material and some enzymes of the secretion. Maximum secretion of enzyme occurs within the first 3 days of the digestive cycle and protein reaches its maximum at 4 days. Phosphatase, proteinase, nuclease and amylase have been observed in the secretion. The enzymes have acid pH optima and the proteinase has a molecular weight of about 40,000.
