The stolon and shoot stem leaf temperature of Wedelia prostrata Hemsl was investigated in comparison with the meteorological environmental conditions. The maximum leaf temperature was 33.4℃ in the case of the stolon stem and 40.5℃ on the shoot stem. However,the air temperature near the stolon stem leaf was 44.0℃,and the sand surface temperature was 63.0℃. The correlation coefficient between the leaf temperature and the meteorological conditions is as folIows: 1.Air temperature (x) and relative humidity (y) near the stem
