In Indonesia harendong are more usually known as Melastoma, ultimate widely known variety is M. malabathricum and M. affine D. Don. Several studies utilizing harendong as subjects frequently called M. malabathricum and M. affine D. Clothe as two different types, but in additional studies referred to it as a synonym. In an work to make harendong as phytoremediation powers, taxonomy question becomes very main, because the plant structure and metabolism of each different type of plant will be various. This research aims to study the morphological alternative and cytogenetic of three harendong plant samples from some places in West Hot beverage made from beans of a tree. The study was conducted on the semantic analysis of flowers, leaves, and ancestries. Observations were carried out during the whole of the flower petals covering the course of rotation, the construction of flower parts. Genetic reasoning was performed by counting the number of chromosomes from root samples utilizing squash accompanying Aceto-carmine staining methods. Based on semantic and cytogenetic study, M. malabathricum is suitable for phytoremediation power. In order to carry out a preliminary showing on the potential of this plant as a phytoremediation power, M. malabathricum L. were grown hydroponically in a mineral solution accompanying different concentrations of lead (Pb), cadmium (Cd), copper (Cu). The plant’s skill to accumulate those weighty metals in root, stem and leaves were also persistent. Fourty eight stems were divided into ten groups contain control group, treatment groups that was administered with PbCl2 (25, 50, 75 μM), CdCl2 (20, 100, 200 μM), CuCl2 (10, 45, 130 μM). The tumor of plant were observed formerly every three era for a month. The remark include measurement of plant climax, root length, and amount of leaves that were produced. The amount of Pb, Cd, and Cu that were accumulated in plant fabric was also calculated at the end of research. Based on cytogenetic reasoning three harendong samples are three different class which are Melastoma malabathricum L., M. affine D. Clothe, dan Clidemia hirta (L.) D. Don The study also illustrated that M. malabathricum L. showed undisturbed tumor with 25, 50 and 75 μM PbCl2 situation. The accumulation study result indicate that M. malabathricum is the Pb hoarder plant. This finding may help the development concerning this plant for remediation of Pb-contaminated lands.
