Utricularia ochroleuca R. Hartm.

Material examined.

RUSSIA, Tyumen Reg. - Tobolsk distr. • 9.5 km E of Tobolsk, E of the “Tobolsk-Polymer” site; 58.2302°N, 68.4745°E; reservoir off the dam, covered with plants shallow water off the shore; 19 Jul. 2019 (Fig. 1 ) .

Note.

There is one specimen without flowers. This species differs from the closely related Utricularia intermedia Hayne by the presence of single vesicles on green photosynthetic leaves and by the pointed segments of green leaves ( Taylor 1989; Lisitsyna and Papchenkov 2000). For Western Siberia, the species was not previously recorded ( Lisitsyna and Papchenkov 2000; Doron'kin 2012).

New records of some rare species have been documented in areas that were not previously known to occur within the studied administrative districts of Tyumen region ( Glazunov et al. 2017).
