Biosystematics is simply known as “the study of biodiversity and its origins”.
The word systematics is derived from the Latin word `systema‘, which refers to organisms’ systematic arrangement.
Biosystematics is an art as much as a science.
Biosystematics is a synthetic branch that uses the characters and data from many disciplines like morphology, anatomy, cytology, genetics, palynology, embryology, ecology, plant geography, phylogeny, physiology, phytochemistry, evaluation, and paleobotany.
Hence, biosystematics is an integrative and unifying science.
