喇叭爬行植物Campsis radicans（L.）的研究似乎。（Bignoniaceae），揭示了五种不同的蜜腺系统，这一现象从未在温带植物中报道过。以四种花外系统为中心的蚂蚁活动清楚地表明，通常只与热带或亚热带物种相关的蚂蚁防御共生关系。花蜜是一种吸引蜂鸟和大黄蜂的传粉媒介，与花外产生的吸引蚂蚁的花蜜在化学上不同。
Studies of the trumpet creeper,Campsis radicans(L.) Seem. (Bignoniaceae), reveal five distinct nectary systems, a phenomenon never before reported among temperate zone plants. Ant activity, centered around the four extrafloral systems, clearly demonstrates the ant-guard symbiosis usually associated only with tropical or subtropical species. Floral nectar, an attractant for hummingbird and bumblebee pollinators, differs chemically from the ant-attracting nectar produced extraflorally.
