The CO 2 content of the interstitial water of a Danish Lobelia lake was between 1 and 5 mmole liter −1 . Measurements showed that the sediment must liberate CO 2 to the lake water in amounts sufficient for optimal photosynthesis of Lobelia. Zonation of Isoëtes, Littorella, and Lobelia in the lake cannot be correlated with the CO 2 content of the sediment.
