Abstract: We compared the phenotypic characteristics of Dicranostigma leptopodum under 2 light environment to explore the effects of different light habitat conditions on the phenotypic diversity of D. leptopodum. The results showed that there was abundant intraspecific diversity of D. leptopodum; full light environment result in a situation of spindling, and the viewing effect is not ideal; the condition of high light(100% light conditions) tends to result in a significant increase in the length of the basal leaves and stems of D. leptopodum; suitable shade environment(60% light conditions) could increase the number of stem branches(number of flowers), the size of petals, the number of basal leaves and the coverage of D. leptopodum.
