The Distribution, Ecology and Status of a New Canadian Endemic, Lori’s Water-Lily (Nymphaea loriana).

Lori’s Water Lily (Nymphaea loriana Wiersema, Hellquist & Borsch) is a newly discovered, endemic species found in Manitoba and Saskatchewan. Morphological and molecular investigations have shown that N. loriana arose via hybridization between Pygmy Water Lily (N. leibergii) and Fragrant Water Lily (N. odorata). The plants observed in Canada are fertile and form self-sustaining populations unlike other hybrids between these species observed in the U.S.A. The species’ extent of occurrence (EO) is ~15,100 km2 but the known area of occupancy only 20 km2. The estimated population size in Canada is 750 individuals although more may exist on poorly explored rivers and lakes within the EO. Nymphaea loriana occurs in fresh, slowly moving water in boreal lakes and rivers, and is associated with Yellow Pond-lily (Nuphar variegata) and N. leibergii. Potential threats to this species include lower water quality, and changes to water flow due to dam construction and/or climate change. Legal protection of this species is recommended.
