Morphology
three-seeded + mercury
The phrase is a descriptive compound: 'three-seeded' clearly means 'having three seeds' and 'mercury' here functions as the plant name, so the overall meaning ('a mercury plant that has three seeds') is directly derivable from its parts. Although 'mercury' has other senses (element, planet), in a botanical context learners who know both constituents will readily interpret it as the name of a plant, making the expression compositionally transparent.
Etymology
Three-seeded mercury comes from a simple picture: the plant has tiny seed pods that usually hold three seeds. The word mercury was once used for small wild plants, so calling it three-seeded made the little 'weed' easy to remember and identify by its three seeds.
