The variability of morphological chaiacters in the material from different regions has been studied. Multi-varied statistics methods have been used. G. aparine is considered to be the only species of the group in East Europe and Caucasus. M.V. Nilova Summary Stem and wood anatomy was described in two species of Chrysobalanacecle . Chrysobalanus icaco and Licania tomentosa.
Primary bark consists of parenchyma and becomes deformed at early stages.
Primary phloem was represented by thin in section fibres forming a broken ring. The phloem of Chrysobalanus also contains sclereids. Sieve plates are compound, each with 25-30 sieve areas. The secondary phloem in perennial stems consists of sieve tubes with companion cells, storage and crystalliferous parenchyma and sclereids in both species. Licania possesses also the fibres.
