Anthropogenic enrichment of aquatic ecosystems is an increasingly common phenomenon, resulting from human population growth and the intensification of industrial and agricultural developments. Eutrophication has been considered to be one of the main causes of the decline of many aquatic plants.

Baldellia ranunculoides (L.) Parl. (Alismataceae) is a taxonomically problematic aquatic plant with an historically ill-defined distribution and global conservation status. This paper finds morphological, ecological and molecular evidence for two distinct taxa, probably best described as subspecies: (1) B. ranunculoides subsp. ranunculoides and (2) B. ranunculoides subsp. repens and provides...
