period of its career, yet it has a single stem and a good leader, so should 

 in time make a satisfactory tree. Its height is 17 ft. and girth 3 ft. 

 above ground 1 ft. 2 in. (fig. 26). 



I am afraid I must dissent from the remark of Mr. Elwes in " Trees 

 of Great Britain " that this hybrid has nothing to recommend it from 

 an ornamental standpoint, and that it is in all respects inferior to a 

 Lucombe. The leaves of my plant are quite evergreen, over 4 in. 

 long and of a rich bright green, and have shallow irregular lobes. 

 1 know that the foliage of Q. X Lucombeana varies enormously both in 

 shape and in deciduous or evergreen character, and when one sees 

 a plant which is apparently almost pure Cerris, and another which 

 might be a true Q. Suber, it is very difficult to believe that both have 

 the same parentage. Although at various times I have seen Lucombes 

 extraordinarily diverse, I have yet to come across one with foliage 

 as fine as my Q. X Turneri. Both my plants would be classed by some 

 botanists as a variety of the type, namely, Q. X Turneri pseudo- 

 Turneri, but since, as pointed out by Mr. Bean, there is a tree growing 

 at Kew which bears both the typical leaves, and those which 

 characterize the variety, I am inclined to agree with him that it is 

 not desirable to draw any distinction between the two forms. More- 

 over, the name pseudo-Turneri seems to me peculiarly ill-chosen. 



It is well to speak of a maple as Pseudo-platanus and of 

 a robinia as Pseudacacia, for in both those instances the leaves 

 of the particular tree simulate those of another which belongs to 

 a totally distinct botanical order, accordingly that is a judicious 

 use of the Greek word for * false ' ; on the other hand, to call a form 

 of Turner's oak which happens to have unusually long leaves Q. Turneri 

 pseudo-Turneri is to employ a contradiction in terms, and to say in 

 one breath that an oak is, and is not, Turner's. These criticisms 

 do not apply to the name Q. pseudo-Suber, for whether or not that 

 tree be a hybrid it is not the true unadulterated Q. Suber. 



Q. utahensis (Rydberg). — This deciduous oak is quite a recent 

 introduction to England, and was first received at Kew as late as 

 1912. I have a healthy little plant 2 ft. 6 in. high, which was kindly 

 sent me last year from that institution. It is a native of the mountains 

 of Utah, Colorado, Arizona, and Kew Mexico, at an elevation of 4000 

 to 9000 ft. It is quite a small tree, not attaining to a height of 

 more than 10 metres. 



The leaves are broadly obovate, 6 to 10. cm. long, with 7 to 

 9 oblong to obovate lobes ; they are rounded at the apex, where they 

 are seldom lobed ; there are deep spaces (sinuses) of varying size 

 between the lobes. The texture of the foliage is thick and firm and 

 the colour dark green ; the upper side is shiny and slightly hairy, 

 while the under side is almost velvety, paler in colour, and showing 

 prominent venation. The ovoid-oblong acorns 1*5 to 2 cm. long are 

 nearly sessile, and ripen in one season ; they are set about half-way 

 in the cups, which are covered with ovate, corky, thickened hairy 

 scales. The above is founded on information with which the Director
