For efficient use as food and medicine, accurate identification of species of medicinally important plants is valuable. The goal of the study is to identify the critical macro and micro morphological characteristics for diagnostic purposes and to determine the evolutionary connections of two medicinal crops sequence. The two taxa of our species group's sequences, Phyllanthus amarus and Phyllanthus tenellus, were taken from the national center for Biotechnology's technological home page. Utilizing the neighbours joining strategy, the evolutionary history was deduced. The morpho-anatomical features are regarded as important diagnostic indicators for verification of. It is clear that the genus Phyllanthus tenellus belongs to the phyllanthacae family, which has been studied earlier in current taxonomic schemes.
