13 1 8 The Trees of Great Britain and Ireland 



Garden at Chiswick, which had been received from Pesth, under the name Q. conferta ; 

 and Gordon,^ in a list of the plants cultivated at Chiswick in 1839, enumerates 

 Q, pannonica, which had been obtained from Booth of Hamburg, Grafted plants ^ 

 were sold soon afterwards in considerable quantity by Lawson of Edinburgh. 

 The species is, however, quite rare in England, though it seems to grow well 

 where it has been planted in the southern and midland counties. 



The largest we know is at Orton Hall, which in 1905 measured 68 ft. by 8 J ft., 

 and is apparently grafted on the common oak (Plate 331). At Beauport there is 

 a fine tree 67 ft. by 7 ft. 3 in. in 1909. At Westonbirt a well-grown tree in the 

 arboretum measured 53 ft. by 5 ft. in 1909. At Kew^ a fine young tree is about 

 45 ft. by 6 ft. At Tortworth a well-shaped and thriving specimen was 41 ft. by 3 ft. 

 in 1904. At Osterley Park, there are two healthy young trees about 35 ft. high. 

 Smaller ones are growing at Bicton, Grayswood near Haslemere, Liphook, Saw- 

 bridgeworth, and Aldenham. 



In the Edinburgh Botanic Garden, a tree,* planted in its present position by 

 Sir W. Gibson Craig in 1866, measured in 1905, 39 ft. by 5 ft. ; and another, planted 

 by Dr. Masters in 1875, measured in 1905, 30 ft. by 3^ ft. (H. J. E.)

 obovate leaves averaging 4 in. long and 3 in. broad, the narrower oval leaves nearly 

 as long, and about 2 in. wide ; acute at the apex ; truncate, rounded, or auricled at 

 the base ; with nine to fourteen pairs of lateral nerves, each, except the lowest one 

 or two pairs, ending in a rounded or acute tooth or short lobe ; upper surface dark

^ This tree is mentioned under the name Q. sessiliflora pannonica, by Hemsley, in Gard. Chron. iv. 455 (1875). 

 This tree was 20 ft high in 1876, and was one of Lawson's original plants, which had been for some time in the 

 garden in an unsuitable site. Cf. Gard. Chron. v. 86 (1876).
