6.  Geum peckii Pursh NC

White Mountain avens. Acomastylis peckii (Pursh) Bolle; Geum radiatum Michx. var. peckii (Pursh) Gray; Sieversia peckii (Pursh) Rydb. • NH. Alpine ravines, cliffs, and plateaus. Reports of this species in VT are erroneous (Zika 1992). Zinck (1994) found no consistent morphological differences between Geum radiatum Michx., a species of the southern Appalachians, and G. peckii. Paterson and Snyder (1999) performed a RAPD study and found that the genetic divergence between these two taxa is comparable to other species. Based on these results, Paterson and Snyder supported the maintenance of G. peckii as distinct from G. radiatum. This means that in the absence of geographic data, one would be forced to examine the DNA to confidently identify some individuals of these species.
