colour. The new evergreen Lucombc oaks are exceedingly rapid in 

 their growth, and very hardy: they are most ornamental trees; and, 

 for producing an immediate and permanent effect in parks, and on 

 lawns, &c., they have no equal. I have seen several instances of their 

 growing vigorously in bleak exposed situations, where the common oak 

 and elm will not succeed : in the vicinity of the sea they grow with 

 great luxuriance ; and, in such situations, are equally valuable with the 

 Q. /Mex. I send you dimensions and specimens of our large trees of 

 each of the three varieties. We propagate them by grafting, in the same 

 manner as we do the old Lucombe oak. Robert T. Pince. Exetei- 

 Nursery, April 4. 1837." 



Mr. Pince remarks, in a subsequent letter, which accompanied some 

 specimens of bark of all these varieties : " I wish particularly to call your 

 attention to the specimens of bark of the varieties of the new evergreen 

 Lucombe oaks, which I send you herewith. You will observe that they 

 are very corky. The produce of hybrids often assimilates to one parent 

 more than to another : and thus, in the varieties of the new Lucombe 

 oak alluded to, there is a great assimilation to the male parent, Q. Suber, in 

 the thickness and texture of the bark, the density of the wood, and the 

 dark green, almost black, evergreen foliage ; whilst, in the conical shape 

 of the tree, and its rapid growth, the habits of the female parent are 

 retained. Id. April 20."

corky. Fig. 1717. c shows the form 

 of the leaf, in its natural size ; and 

 Jig. 1718. is a portrait, by Mr. Gendall 

 of Exeter, of the specimen tree in the 

 Exeter Nursery ; which, 45 years planted, is 63 ft. high ; and the 

 diameter of the trunk, at 1 ft. from the ground, is 3 ft. The bark, 

 from the specimens sent to us, bears a close external resemblance to 

 that of the cork tree, and is above 1 in. thick. 



Q. C. 11 L. suberosa, Q. L. suberosa Hort. t (fig. 1717.) has the leaves 

 somewhat longer, and the bark double the thickness of the preceding 

 variety ; the specimen sent us measuring 2 in. in thickness. The
