worth Nursery, which has been 40 years planted, being only 

 from 22 it. to 25 ft. high, with a trunk 1 ft. 8 in. in circum- 

 ference at 5 ft. from the ground. Two trees in the Hammer- 

 smith Nursery, about the same age, are rather higher. Trees 

 in nurseries, however, are seldom fair specimens, as they 

 are kept there for the purpose of supplying scions for bud- 

 ding or grafting. The tree in the Horticultural Society's 

 Garden has attained the height of 12 ft, in 10 years ; and one at Ham 

 House was, in 1834, 42 ft. high ; the diameter of the trunk 1 ft. 6 in., and 

 of the head 18 ft. Neither this tree nor that in the Sawbridgeworth Nursery, 

 nor any other that we have heard of, has yet flowered.

Spec. Char., fyc. Leaves ovate or oblong, obtusely dentate, smooth, and of the 

 same colour on both sides. Footstalks short. Found about 1825, in a bed of 

 seedling oaks in the Bristol Nursery, where the original plant, in May, 1837, 

 was between 8 ft. and 9 ft. high, with a trunk 8 in. in circumference at 1 ft. 

 from the ground. Propagated by grafting on the common oak. It is a 



1811 



decidedly subevergreen bush, and not a tree j whence has arisen the 



popular name of humilis. In summer, the leaves, at a distance, bear a 



considerable resemblance to those of the common oak ; but, on a nearer 



inspection, they appear as in fig. 1811. or in fig. 1810.: the first from the 



specimen tree in the Hackney arboretum, and the second from the arboretum 



at Milford. Towards the autumn, those shoots which have continued 



growing, exhibit leaves on their extremities so exactly like those of Q. 



Turner*, that it is altogether impossible to make any distinction between 



them This is so very strikingly the case 



at Messrs. Loddiges's, that, if it were not 



from the totally different habit of Q. 



Turner/ and Q. hybrida nana, we should, 



from the appearance of the leaves, which 



remain on, in both species, at the points 



of the shoots, after all the others have 



dropped off, consider them to be the same 



species. Fig. 1812. exhibits leaves taken 



from the extremities of the shoots, in different parts of the same plant, 



in the Horticultural Society's Garden, in May, 1837.
