Discussion

Species 1: wc North America.

Analysis of molecular data reported by D. E. Soltis et al. (1990) has suggested that Conimitella is far more closely related to Mitella diversifolia, M. stauropetala, and M. trifida than previously believed on morphologic grounds. They made a strong argument for including Conimitella within Mitella; they deferred making nomenclatural changes until further studies are completed.
