Abstract: The histochemical studies on the 5 variants of Viscum (A-E) showed important observation that only 3 different types of crystals are present. These are crystal sand, circular and rectangular crystals. Variants A has circular crystals at the leaf and crystal sand at the stem. Variant B has rectangular and circular crystals at the leaf and crystal sand at the stem. Variant C has circular crystals at the leaf and crystal sand at the stem. Variant D has rectangular and circular crystals at the leaf and crystal sand at the stem and finally Variant E has rectangular and circular crystals at the leaf and crystal sand at the stem. The similarities and variations in shapes of these oxalate crystals among the investigated variants of Viscum are discussed in relation to their biosystematic relevance.
