A quantitative accounting of the solids in the sieve tube sap from Macrocystis pyrifera (L.) e. Ag. was performed. The major organic compounds (mannitol, amino acids, and protein) and inorganic cations (K + , Na + , Mg 2+ and Ca 2+ ) were present near previously reported levels. The anions, until now unreported (except for iodide), included chloride as the major inorganic ion, bromide, phosphate, nitrate, and bicarbonate as the major inorganic carbon species. Sulfate and ammonium were below the detection limits of 1.5 ppm and 2 ppm, respectively. The elements B and As were also present although their speciation was not determined.
