The results showed that the plant's diversity and similarity in the three sites growing area of S. jamaicensis habitat were different. There were five plant species obtained in the three sites growing area of S. jamaicensis i.e. Axonoppus compressus (Swartz) Beauv., Centrosema pubescent Bth., Chromolaena odorata (L.) R.M. King & H.
