The relationship between malic acid production and carbon assimilation was examined in the submerged aquatic Crassulacean acid metabolism (CAM) plant, Isoetes howellii Engelmann. Under natural conditions free-CO(2) level in the water was highest at 0600 hours and (14)CO(2) assimilation rates in I.
Isoetes bolanderi dominates the littoral flora of Siesta (elevation 2,440 m) and Ellery (2,905 m) lakes in the Sierra Nevada Range of California, USA. Both lakes are sparesly vegetated and I. bolanderi maintained aboveground oven dry weight of 30-50 m-22 through most of the 1981 summer growing
