Range Extent Comments: Nymphaea leibergii occurs from northern Maine and Quebec west to British Columbia, and south to Michigan (Isle Royale), Minnesota, and Montana. Historical in Idaho. Currently reported as very common in Alaska by Heritage records. According to Wiersema (1995), however, plants in Alaska are all N. tetragona ssp. tetragona, and N. tetragona ssp. leibergii does not occur in Alaska.

Number of Occurrences: 21 - 80
Number of Occurrences Comments: EOs: 22 in Minnesota, 2 in Michigan. Collections (listed in Wiersema 1995): 2 in Montana, 4 in Maine, 4 in Quebec, 5 in Manitoba, 4 in Saskatchewan, 1 in Alberta, 3 in British Columbia. Historical in Idaho, the type location. Most common in Ontario (at least 20 collections). Collections may underrepresent the actual number of EOs for this species because it occurs in remote, undersampled habitats.

Population Size Comments: Most abundant in Ontario.

Overall Threat Impact Comments: The primary threat to Nymphaea leibergii is a change in the water quality of its habitats. Threats include nearby logging, siltation, nutrient loading, and eutrophication. Also threatening is succession of and competition with emergent vegetation.

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: Occurs primarily in remote ponds and streams and has adapted both to beaver and to human impoundments.

Ecology & Life History

Basic Description: Pygmy water-lily, dwarf water-lily; Water-lily family (Nymphaeaceae). A perennial, herbaceous, rooted, aquatic plant with elliptic, floating leaves that arise directly from the rhizome.
General Description: Pygmy Water-lily is an herbaceous perennial with submergent stems and floating leaves arising from a thick rhizome. The leaves have a long, slender petiole attached to the base of a long, v-shaped notch in the elliptic blades that are 7-10 cm long. The bowl-shaped flowers have long, slender stalks and float on the surface of the water. Each flower has 4 light green, narrowly elliptic sepals that are 2-3 cm long and 7-15 white, narrowly lance-shaped petals of the same length. There are 30-45 yellowish stamens, and the stigma is large and saucer-shaped. The fruit is woody and berry-like.
Diagnostic Characteristics: BRASENIA SCHREBERI does not have a notch in the leaves. NUPHAR has yellow flowers, and the lower leaf surface is not as purple as in NYMPHAEA. NYMPHAEA ODORATA has larger leaves, 20-30 petals, and 50-100 stamens.
Habitat Comments: Nymphaea leibergii generally occurs in clear water, with a neutral or slightly alkaline pH, over a rich, organic substrate. Its habitats include ponds, shallow lakes, slow-moving streams, and edges of slow, open water channels through marshes, up to a depth of approximately 2 m. N. tetragona may also occur in streams impounded by beavers or by humans.
