Suaeda monoica, a C(4) Plant without Typical Bundle Sheaths.
Suaeda monoica Forssk. ex J. F. Gmel was found to possess the C(4) pathway of photosynthesis. The succulent leaves of Suaeda lack a green bundle sheath formation but have a layer of chlorenchyma, containing large and centripetally arranged chloroplasts, which surrounds the water tissue. We suggest that the proximity of a chlorenchymatous cell layer to the vascular bundles is not necessary for the operation of the C(4) pathway.
