Nymphaea odorata Aiton ssp. odorata . Subgenus: Nymphaea. White Waterlily. Phen: Jun-Sep. Hab: Ponds, sluggish waters. Dist: NL (Newfoundland) west to MB, south to FL and TX and n. Mexico; also scattered in the w. United States as an introduction.
Origin/Endemic status: Native
Taxonomy Comments: N. odorata is polymorphic, leading to the naming of numerous species, subspecies, and varieties (see synonymy for a few of the named entities). Wiersema in FNA (1997) recognizes ssp. odorata (most of our plants) and ssp. tuberosa (Paine) Wiersema & Hellquist, more western and northern, but edging into our area. Other named entities warrant further evaluation. N. odorata var. gigantea [= Castalia lekophylla Small] occurs on the Coastal Plain, and is considered to differ from var. odorata in its larger leaves (1.5-6 dm in diameter vs. 0.5-2.5 dm), larger flowers (mostly > 15 cm wide vs. mostly < 10 cm), and leaves upturned at the margins (vs. flat). N. odorata var. minor [= Castalia minor (Sims) Nyar] is considered to differ from var. odorata in its generally smaller size, leaves 5-11 cm in diameter, flowers mostly < 8 cm wide (vs. mostly > 9 cm wide); it may be merely a dwarfed form of extremely nutrient-limited waters of the Coastal Plain.
