The Casparian strip thickening occurs on the endodermis. The number of protoxylem groups in root is five to nine. In stem, 12-18 vascular bundles are arranged in 2-3 circles. Palisade tissue and spongy tissue can be distin-guished in the mesophyll. In the former, the chloroplasts are bigger and dark green; in the latter, the chloroplasts are smaller and pale green.
