Limonium sinense (Girard) O. Kuntze (Plumbaginaceae) and Suaeda salsa (L.) Pal. (Chenopodiaceae), both typical halophytes, have been used to investigate the peculiar structural features adapted to saline conditions, with a special emphasis on the anomalous secondary structure of stem and root. The results showed that in saline environments, L. sinense developed tripartite vascular cylinders in the root and cortical bundles in the scape. Suaeda salsa developed concentric rings of vascular tissue and interxylary phloem in the root and stem. Based on these findings, we discuss the adaptive significance of these anomalous secondary structures for plants living in saline environments.
