The eggplant is a specie of genus Solanum, of great importance in horticulture of colombian Caribbean region. The objective of study was to describe the floral morphology of two cultivars of eggplant "Long Purple" and "Lilac land race", which have different geographic origin. We used a random sample of 100 floral cushions for cultivar. The mean, range, variance, standard deviation, variation coefficient were estimated. The t-test was applied to determine differences between two cultivars. The results indicated that genotype 'Long Purple', showed distylics flowers, while in the "Lilac land race" was observed the presence of tristylics flowers. The potential for production of fruit was 76.50% and 57.52% for the "Lilac land race" and "Long Purple", respectively. Brevistylics flowers in the two cultivars, increased male fitness and thus produced a nonbalance on functioning between male and hermaphrodite flowers.
