*** Foliage evergreen, or very nearly so. Leaves varying from dentateto sinuate. Cups of the Acorns bristly.

This section consists entirely of subvarieties of the Lucombe oak,which differ from the parent in being nearly evergreen ; and respectingwhich the following observations have been obligingly sent to us byMr. Pince : — “ These subvarieties were all raised by the present Mr. Lu-combe, from acorns gathered from the old Lucombe oak, about 45 yearsago (1792). Of the first three of these, there are large specimens in theExeter Nursery; being the original trees selected by Mr. Lucombe, andfrom which the plants exposed for sale are propagated. These finetrees,” Mr. Pince continues, “ which are the admiration of all who visitthe Exeter Nursery, differ in many very material respects from theirparent, but in nothing so much as being evergreen. There is a peculiaritym these trees, however, as evergreens, which deserves to be noticed. Itis, that in the month of May, when the young leaves burst forth, the oldones, which are still quite fresh and green, are entirely and simul-taneously cast off, so that the tree appears bare; but so rapid isme change, that a few days suffice to clothe it afresh in full verdure.Therefore, although these varieties are, to a great extent, decidedlyevergreen, they cannot strictly come under that denomination. Thebark is very corky, and the leaves are of a glossy blackish green
