16. Trautvetteria Fisch. & C.A. Mey.
One species,
North America, Asia.
Recent studies
(Ro and McPheron, 1997; Johansson, 1998) suggest that Trautvetteria is
very closely related to a group of species that have traditionally been placed
in Ranunculus. Additional research is necessary to reevaluate generic
limits within this group. For further discussion, see the treatment of Ranunculus
cymbalaria.
