Discussion

Clintonia umbellulata and C. borealis are allopatric in the southern Appalachians (P. P. Gunther 1972). A putative hybrid between the two, C. allegheniensis Harned (J. E. Harned 1931) is not recognized here and is regarded as a mere fruit-color variant of C. umbellulata (F. H. Utech 1973). Isozyme evidence supports this conclusion (M. T. Blain 1997).
