Common Oak 293 



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 sessiliflo7'a or Mirbeckii. 



7. Var. iberica, Hort. — This variety, as cultivated at Kew, has small oblong- 

 ovate 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 pedtmculata 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. VsiV. pinnata, Hort. — Leaves deeply pinnate, the sinuses extending almost 

 to the midrib. 



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

 summer. 



12. V2S. 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. variegaia, Hort. — Leaves variegated either with white or yellow tints. 



14. Var. aurea, DC. Pi-od. 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 ZabeF 

 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. dschoroche?isis, 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.
