Rh Hamburg, who stated in their catalogue that it came from Afghanistan; but Petzold and Kirchner, loc. cit., consider this origin to be improbable. What is sold under this name in some nurseries is sessiliflora or Mirbeckii.

7. Var. iberica, Hort.—This variety, as cultivated at Kew, has small oblongovate leaves, broad and cordate at the base, acute at the apex, with numerous small deltoid lobes, each terminating in a callous acute tip, the margins of the lobes being often turned downwards and inwards.

8. Var. falkenbergensis, Hort.—This has small dark-green leaves, broadest in diameter in their upper third, lobes few and broad, and the base generally cordate and auricled. The fruit is sessile or on short peduncles. It is very probably a hybrid between Quercus pedunculata and Q. sessiliflora. This variety was found in 1832 in a wood at Falkenberg in Hanover, and was put into commerce by Messrs. T. Booth and Sons in 1837.

9. Var. alnoides, Hort.—This variety, as cultivated at Kew, has small leaves, not exceeding 2 inches in length, with about eight pairs of small lobes, the apex of the leaf being generally acute, the base cordate or cuneate.

10. Var. pinnata, Hort.—Leaves deeply pinnate, the sinuses extending almost to the midrib.

11. Var. rubicunda, Hort.—Leaves deep red, more especially in the early part of summer.

12, Var. purpurea, Hort.—Leaves purple, becoming green with reddish nerves in early autumn. This variety, according to Mr. Nicholson, is a thoroughly distinct and valuable ornamental tree.

13. Var. variegata, Hort.—Leaves variegated either with white or yellow tints.

14. Var. aurea, DC. Prod. xvi. 2, p. 9 (1864). Quercus aurea, Kitaibel, in ''Reichb. Icon.'' xii. 8, t. 645 (1850).—The leaf has generally six pairs of deeply cut lobes, rounded at the top. The young shoots bear yellowish leaves, and are themselves deep yellow. This occurs wild in Austria, and is considered by Zabel to be a hybrid between Q. conferta and Q. lanuginosa; but a type specimen at Kew does not show evidence of Q. conferta parentage.

15. Var. dschorochensis, Hort.—The variety which is cultivated under this name does not seem to be the species found by Koch on the Dschoroch range of mountains near Trebizond in Asia Minor; and at Kew is apparently a form of sessiliflora with oblong-oval leaves, which have eight or nine pairs of very shallow sinuate lobes.
