24?2 The Oak Tree, considered 



bristles), does not by any means agree with his lengthened 

 description, when he says that these peduncles are clothed 

 v^\\kifine silky hairs. My plant is certainly E. Iatif51ium; and 

 should I have made an error in supposing it to be Dr. Smith's 

 E. pubescens, I hope some of your readers will correct me, 

 and put into my possession the true plant of the English 

 Mora, 



I can scarcely pass over in this place the E. angustifolium. 

 This has the leaves almost linear, and I feel doubtful about 

 its being so common as is usually thought, most specimens 

 I have seen under that name being E. polystachyon. The 

 synonym of Vaillant [FL Par,, 1. 16. f. ].)j or -E. Vaillant/z 

 Poiteau and Turpin (JF7. Par,, t. 52.), has been cited under it 

 by Sir James ; and .of that plant Merat says the leaves are 

 triangular, but Gaudin that they are somewhat broad and 

 carinate ; and in my specimens from Paris, given me by M. 

 Adolphe Brongniart, the leaves are lanceolate, and only tri- 

 angular towards their points. Hence, as the peduncles are 

 perfectly glabrous, I would refer it to E. polystachyon. It is, 

 however, I allow, a remarkable variety, as the lower or broad 

 part of the leaf appears complicate or folded together; a cir- 

 cumstance that may have led some botanists to suppose that 

 the base was itself triangular. 



Most foreign botanists make but two species of E. angusti- 

 folium, latifolium, and polystachyon, and distinguish them by 

 the smooth or scabrous peduncles. E. gracile is separated 

 fi'om them by its filiform and triangular leaves, erect spikes, 

 and hirsute peduncles ; but, in my opinion, it bears precisely 

 the same relation to E. angustifolium that E. Iatif61ium does 

 to E. polystachyon.

Art. X. The principal Forest Trees of Europe, considered as 

 Elements of Landscape, By J. G. Strutt, Esq. 



{Continued from p. 42.) 



In my former communication, I endeavoured to give your 

 readers an idea of the general figure and character of the oak, 

 with respect to pictorial effect in landscape, whether considered 

 as a solitary object to adorn the foreground, or as united into 

 groups, or as the extensive line of a distant forest. I then 

 found it sufficient to arrange my subject in three principal 

 divisions, the stem, the limbs, and the masses of foliage; I
