Erratum.
The last sentence of the report "Crassulacean acid metabolism in the strangler Clusia rosea Jacq." (6 Sept., p. 969) was incorrectly printed. It should have read, "The 1985 expedition was led by I. P. Ting and J. Hann, with L. Blose, R. E. Bonning, J. C. Broyles, D. W. Stewart, and J. A. Zabilski as participants."
