Juglans alba Linnaeus, Species Plantarum 2: 997. 1753.

"Habitat in Virginia." RCN: 7224.

Type not designated.

Original material: Kalm, Herb. Linn. No. 1129.2 (LINN); Clayton 466, Herb. Linn. No. 79 (SBT); Clayton 466 (BM); [icon] in Catesby, Nat. Hist. Carolina 1: 38, t. 38. 1730; [icon] in Plukenet, Phytographia: t. 309, f. 2. 1694; Almag. Bot.: 264. 1696 - Voucher: Herb. Sloane 101: 57 (BM-SL) .

Current name: Carya tomentosa (Poir.) Nutt. ( Juglandaceae).

Note: This name was treated as ambiguous by Rehder (in J. Arnold Arbor. 26: 483. 1945) on the grounds that it was a mixture of Carya ovata (Mill.) K. Koch - Shagbark Hickory (the Plukenet element) and C. tomentosa (Poir.) Nutt. - Mockernut Hickory (Gronovius, Parkinson, Catesby and Kalm elements). Some (e.g. Howard & Staples in J. Arnold Arbor. 64: 527. 1983) appear to have used the name C. alba (L.) K. Koch for C. tomentosa, wrongly believing Crantz to have effectively typified the name on the Catesby element. There may well be a case for rejection. See also comments by Wilbur (in Sida 14: 36. 1990), who supports this solution.
