Root, stem and leaf anatomy of Geranium palustre Torner Cent. (Geraniaceae).
An anatomical study on the root, stem and leaf of Geranium palustre Torner Cent. has been performed in order to continue our previous researches on this species. Technique of inclusion into paraffin and optical microscope have been used. Root, stem and leaf transverse sections were studied. They contain calcium oxalate crystals as inclusions. The root presents elements of secondary structure (suber, secondary cortex, secondary xylem and phloem). The vascular bundles in the stem can be classified as internal or external and differ in the presence or absence of an own sclerenchyma sheet depending on their age. The vascular bundles of stem are collateral. Leaf structure is bi-facial. Stem and leaf surface have no glandular hairs.
