The correct name for a section of Ludwigia L. (Onagraceae)

摘要

In 1953, Hara provided new combinations for many sectional and species names when he combined Jussiaea L. with Ludwigia L., and at the time, Ludwigia sect. Oligospermum (Micheli) H.Hara was the correct name for one well-defined section. However, subsequent changes to/clarifications of the botanical code have necessitated a change for that name in that now an autonym is treated as having priority over the name or names of the same date and rank that established it. Since Hara’s combination was based on Jussiaea sect. Oligospermum Micheli, the correct name for this section is Ludwigia sect. Jussiaea (L.) Hoch, W.L.Wagner, & P.H.Raven.
