3. Var. Dalechampii, Koch, Dendrol. ii. 2, p. 38 (1873); Quercus Dalechampii, Tenore, Ind. Sem. Hort. Neap. 1850, p. 15; Quercus sessiliflora, var. Tenorei, DC. Prod. xvi. 2, p. 7 (1864).

This form, which is considered by some to be a distinct species, occurs in southern Italy. It is in cultivation at Kew, and has leaves 3 to 4 inches long on short stalks. The leaves are oblong-oval, with bases cuneate or truncate, often auricled, coriaceous in texture, shining green above, bluish and only slightly pubescent beneath, with six to eight pairs of acute shallow lobes, which have their margins curved inwards and backwards. The bark of the tree is very rough and scaly.

    i. 387, is either a form of Q. macranthera or a hybrid of that species. The plant, however, usually cultivated as Hartwissiana is probably a variety of Q. lanuginosa, which Steven collected and described as Q. crispata (Bull. Soc. Nat. Mosc. 1857, i. 386).
