Abstract

Cross sections of leaves of 14 of the 24 plant taxa endemic to cedar (limestone) glades were examined for presence or absence of Kranz anatomy. All 14 taxa are non-Kranz, indicating that they fix carbon by the C3 pathway of photosynthesis. It is highly probable that all 24 taxa are C3 plants. About 95% of the c90 taxa endemic to (unshaded) rock outcrop plant communities of unglaciated eastern US use the C3 pathway, ie the C4 pathway is not required for adaptation to the hot, dry, high-light environment of the rock outcrops. -from Authors
