- The group of Lysimachias containing L. ciliata has recently been set apart as a distinct genus, Steironema, Raf., by Gray Proc. Am. Acad. xii 62 62 because of differences in the æstivation of the corolla; but for our present purposes, Tridynia (containing stricta and quadrifolia), Lysimachia (containing vulgaris), and Steironema may be treated together under the name Lysimachia.
