1719 Utricularia intermedia Hayne

This species is widely distributed in Eurasia and N. America. It belongs to the circumpolar plants (Hultén, Circumpol. Il, p. 106 and map 98). The distribution is partly incompletely known. Cf. also Meusel et al. 1978, map p. 417. - Recently G. Thor has pointed out the existence of the closely related U ochroleuca R. Hartm., an often-overlooked species (Sv. Bot. Tidskr. 73/1979, map p. 392, revised by G. Westman, op. cit. 78/1984, map p. 224).
