STRUKTUR ANATOMI DAUN SEBAGAI BUKTI DALAM PEMBATASAN TAKSON TUMBUHAN BERBUNGA: STUDI KASUS 12 SUKU TUMBUHAN BERBUNGA INDONESIA

Plant diversity can not only be seen morphologically, but it can also be distinguished anatomically. Anatomical characters can be used to support and strengthen the plant classification. This study aims to determine the anatomical character of the leaves which can be used as a taxonomic identifier at the level of taxa through species representation. A total of 15 species belonging to 12 Indonesian flowering plant families were examined using the paraffin method for the transversal section and HNO3 was used for the paradermal section. Some anatomical characters observed in this study can be used as family characteristics or even species characteristics. The result revealed that all examined samples had similar anatomical characters with previous study which been carried out on the family, genus or species level. These similar anatomical characters consist of one to several characteristic such as stomatal type, anticlinal cell wall, mesophyll tissue, and vascular bundle (petiole and midrib). These results indicate that some anatomical characters can be used as specific characteristics from family level to species level.
