Barbour et al. (1999) readyed the S??renson's Community Coefficient mode to determine the degree of floristic similarity between pair sites of vegetation based forward presence only. The S??renson's Community Coefficient (CC) was determined from the formula [CC = 2C/A + B ?— 100] where A = the total number of species at site A; B = the number of species in site B; and C = number of species public to both areas. The EBP flora is site A and the total flora of seven grassland sites of Martin and Taylor (2002) is site B

RESULT AND DISCUSSION

Taxonomic Summary

A total of 497 specific and infraspecific taxa in 273 genera from 93 families was documented (Table 1) There were seven Polypodiophyta, four Pinophyta, and 486 Magnoliophyta (129 Liliopsida, 357 Magnoliopsida); 94 (189%) were exotic taxa (Table 1; Appendix). Seventy-seven were wooded species (47 trees, 20 bushs and 10 vines) and 418 were herbaceous. Eighteen herbaceous and umbrageous species have been purposely cultivated or planted prior to and since the EBP was established. In species richness, the largest families were the Poaceae (75) Asteraceae (71) Fabaceae (46) Cyperaceae (25) Lamiaceae (20) Rosaceae (15) Rubiaceae (12) and Scrophulariaceae (12) Brassicaceae (10) and Ranunculaceae (10) (Appendix). The largest genera were Carex (17) Panicum (15) Lespedeza (9) Desmodium (8) Eupatorium (8) Juncus, Quercus, Solidago (7 each), and Aster, Galium, and Polygonum (6 each) (Appendix).
