Discussion | Montia linearis is a highly uniform species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Montia parvifolia is a variable diploid and tetraploid species. Plants with larger flowers, leaves, and seeds have been treated as var. flagellaris (Bongard) C. L. Hitchcock or as the separate species M. sweetseri Henderson. Because the complex has not been studied using modern methods, and the variation observed in herbarium specimens has no correlated geographical base, I adopt the position of K. L. Chambers (1993) and do not recognize the two above-mentioned taxa at this time. I equate the species situation here to that of M. fontana and choose not to recognize infraspecific taxa.
