Lindernia is a genus of flowering plants placed in the family Linderniaceae (order Lamiales), though some taxonomic backbones still list it under the broader Scrophulariaceae. The genus encompasses approximately 30 species in its most recent circumscription, distributed across warm regions of both the Eastern and Western Hemispheres.
Members of Lindernia are generally small, often annual or short-lived herbaceous plants that favour damp or semi-aquatic habitats. The genus has gained particular attention among aquarists: several species, notably L. rotundifolia, have become commercially available for use in home aquariums and aquascaping, where they are valued for their compact form and adaptability to submerged conditions.
Etymology
The genus name Lindernia honours Franz Balthasar von Lindern (1682–1755), a French physician and botanist based in Strasbourg who also served as director of a university botanical garden.
Distribution
Lindernia species are native to warm regions across both the Eastern and Western Hemispheres. In North America the genus is represented in the southwestern United States and Mexico; the broader genus spans tropical and subtropical zones worldwide.
Ecology
Species in Lindernia characteristically grow in moist or seasonally wet habitats. Several species are adapted to submerged or semi-aquatic conditions, which accounts for their use in freshwater aquariums and aquascaping.
Taxonomy Notes
The family placement of Lindernia has shifted in recent decades. Historically included in the broadly defined Scrophulariaceae, the genus is now placed in the segregate family Linderniaceae following molecular phylogenetic studies. Different taxonomic databases reflect different stages of this reclassification: some GBIF backbone entries retain Scrophulariaceae while others use Linderniaceae.
