The aim of study was to determine the plant tissue nutrient concentration, porosity ratio and nutrient removal ability of four wetland plants, namely Oryza  rufipogon  griff (OR), Hymenachne  acutigluma (HA), Eichhornia  crassipes (EC) and Colocasia  esculenta (CE). Results showed that these species can tolerate to domestic wastewater as well as high N and P uptake. The highest root porosity ratio was 56.19 % in OR whereas CE had the greatest leaf-stem porosity ratio, 60.53 %. Among species, CE and HA had significantly highest biomass (96.77 g and 39.53 g) and RGR (1.68d ^-1 and 0.67 d^-1) meanwhile OR and CE were the most potential candidates for the removal of total-N (85.12 and 84.16 %), total-P (85.24 and 89.43 %) and COD (67.95 and 75.73 %). Correlation between nutrient removal, leaf tissue nutrient content and root porosity ratio were highly significant among plant species. These results therefore suggested that plant tissue nutrient concentration and porosity ratio are useful features for selecting tolerant and efficient species in constructed wetland wastewater treatment facilities.
