由于夏威夷群岛缺乏本地蚂蚁，有人假设，花外蜜腺，蚂蚁相关的互惠性状，应该缺乏本地物种。植物上的花外蜜腺（EFN）的存在是通过直接观察确定的，并与植被结构和花组成。通过所有可能的比较，具有EFN的植物的频率较低。然而，一些特有种功能EFNs。解释这些异常现象的假说是（1）系统发育惯性或（2）与蚂蚁以外的其他生物的互利共生。
Since the Hawaiian Islands lack native ants, it was hypothesized that extrafloral nectaries, an ant-related mutualistic trait, should be lacking on native species. Presence of extrafloral nectaries (EFNs) on plants was determined by direct observation and related to vegetation structure and floral composition. Frequency of plants with EFNs was low by all possible comparisons. However, several endemic species had functional EFNs. The hypotheses to explain these anomalies are (1) phylogenetic inertia or (2) mutualism with some other organism than ants.
