Modern taxonomy has two approaches, i.e. classical and experimental taxonomy. Classical taxonomy uses
morphological characters, while experimental taxonomy uses broader methods including chemistry, physics and
mathematics, in the form of laboratory data that are revealed together with the progress of optical technique
(microscope), chemistry methods (chromatography, electrophoresis), etc. Modern taxonomy tends to use series of
interrelated data. More data used would result in more validity and give better clarification of taxonomic status. A lot of
modern taxonomic data such as palynology, cytotaxonomy (cytology), chemical constituent (chemotaxonomy),
isozyme and DNA sequencing were used recently.
