Culsia rosea (C. rosea) is a tree native to the Caribbean [1]. It produces apple-sized fruits which, after ripening, become eye-catching seed capsules with multiple segments. By examining the seed capsules, we see a direct correlation between the number of seed capsule segments and the amount of seeds that each seed capsule contains. C. rosea is invasive to Hawai‘i and work on its management is unknown [1]. Intuitively, a possible way to combat the spread of C. rosea is to reduce the number of seeds that each tree produces. This process will require knowing the mean number of segments per seed capsule, however this has not yet been determined. In this paper, we counted the number of segments from a random sample of fallen seed capsules collected from three locations. We assumed that for each location the number of segments per seed capsule follows a normal distribution. Hence, we used an Analysis of Variance (ANOVA) and Tukey's range test to assess the null hypothesis that the mean is the same for each location. After performing these tests, we rejected the null hypothesis and we recommend further research into what may have caused the means to be different.
