Valerianella species have unusual, asymmetrical fruits due to the development of only one out of three of the fruit's locules. Many taxa have been named based solely on differences in fruit morphology. However, Ware (1983) determined that a single species may produce 2 or 3 types of fruits within a given population, each type of fruit specific to a given plant. Therefore, the number of species recognized here is fewer than in some other keys. Reference: Dyal (1938).
