Narrative
Collected with Betula lenta near Cressy Creek, Smyth County, Virginia by P.M.Mazzo and F.G.Meyer. These specimens represent the only "cultivated" material in existence, and accordingly document this rarest and unusual North American birch. /A/, /B/, & /C/ assigned to differentiate germplasm source per R. Defeo (4/83). Only plants on west side of Heart Pond are original seedlings; later qualifiers were all grown from cuttings. Grafted plants were distributed in 1984. [Mass of seeds collected from original NA 37939 trees in 2015/2016 was accessioned as NA 83829; out of about resulting 20 seedlings from seeds germinated in 2016, four have the B. uber characteristics and can be considered "true to type"; the rest (which are essentially B. lenta, as the characteristics separating "B. uber" are now believed to be caused by a single recessive gene) will be discarded.]
