With the scoring systems. omamental characteristics of 18 wild herbage flowers were evaluated quantitatively. It was found that the variable score range from 2 1. 5 to 65. in which the variable range of seven herbages for foliage-omamental were 2 1. 5 - 61. seven herbages for flowe r-omamental were 38 - 65. and four herbages for fruit-ornamental were 30-55. According to the quantitative score. the highest omamental value of the herbages for foliage-omamental. flowe r-omamental and fruit-ornamental are Rhaphidophora decursit唱 • Dalphimun omeÎense and Thladiantha nudiflora respectively; and the the lowest ornamental val
