Field observation on the distributions of a coastal plant Ipomoea pes-caprae along the sandy beach of Puducherry (northern part) revealed that Ipomoea pescaprae was growing profusely only along supra - littoral zone (Plant zone) of the sandy coastal region. An attempt to understand the factors that influenced such restricted distribution along the supra-littoral zone revealed that fine sand with medium grains with low pH and EC along with moisture and organic carbon collectively influenced the distribution. Further, ‘t’ test confirmed the observation that pH, Electrical conductivity of the soil, Organic carbon, soil texture, moisture and nitrogen content of the soil are influencing the distribution of Ipomoea pes caprae significant at 99.9% level along the supra-littoral zone in the sandy beaches.
