3. N. tetragona Georgi View in CoL , Reise Russ. Reich 1: 220 (1775).
Like 1 but rhizome erect; receptacle strongly 4-angled; flowers open in the afternoon; sepals persistent and coriaceous in fruit; petals 8-17; connective prolonged into a small conical point beyond the anthers; stigma-rays 7-10. N.E. Europe. Fe Rs (N, B, C).
1-3 are not always clearly separable, probably owing to frequent hybridization. Small plants of N. alba have been called N. occidentalis (Ostenf.) Moss but do not merit specific rank.
