QUERCUS 317 



Var. DIVERSIFOLIA. Leaves of extraordinary shapes ; usually the middle 

 part of the blade is reduced to a narrow strip about in. wide each side the 

 midrib, widening at the apex like the bowl of a spoon, sometimes entire, 

 sometimes three- or five-lobed ; the base with from one to five shallow or 

 deep, rounded or pointed lobes. The leading types of leaves may be described 

 as fiddle-shaped and spoon-shaped. Bark corky ; habit very erect ; ever- 

 green. A small tree. 



Var. FULHAMENSIS. Fulham Oak. As represented at Kew by old trees, 

 this is a tall oak with a round head of branches more slender and graceful 

 than those of Lucombeana or the other varieties. Shoots and under-surface 

 of leaves grey, as in Lucombeana, the latter more coarsely toothed. This 

 variety got its name from a tree that grew for many years in Osborne's 

 nursery at Fulham now built over and originally no doubt a seedling of 

 Lucombe oak, although this particular tree was grafted. 



Q. PSEUDOSUBER, Santi, found in Italy and Provence, is a probable 

 hybrid between Q. Suber and Q. Cerris. The leaves have much the character 

 of some seedlings of Lucombe oak, reverting to Q. Suber. 



Q. LUSITANICA, Lamarck. 



A deciduous tree of middle size, or sometimes shrubby, with a rough thick 

 bark cut up into square scales ; young shoots densely downy. Leaves 

 extremely variable ; commonly oval or obovate, 2 to 3 ins. long, about half 

 as wide ; rounded or unequal at the base, blunt or pointed at the apex, with 

 five to nine coarse triangular teeth at each side ; upper surface dullish grey- 

 green, scurfy downy at first, but ultimately nearly smooth except on the 

 midrib ; lower surface clothed with a close, grey felt ; stalk j to I in. long. 

 Acorns f in. long, clustered two or three together. 



Native of Spain and Portugal ; introduced, according to Loudon, in 1824 ; 

 still uncommon in gardens> A tree on a lawn near the Cactus House at 

 Kew is a spreading, low tree, slow-growing, and of no particular merit. 

 Closely allied to Q. lusitanica and with similar acorns is 



Q. INFECTORIA, Olivier. It is a more Eastern tree, being found in S.E. 

 Europe and Asia Minor, differing from its Western relative in the smooth or 

 nearly smooth leaves and young shoots. As represented at Kew, it is a 

 rather elegant small tree with grey foliage, hard in texture, and not falling 

 till late in autumn. Leaf-stalk smooth, up to i in. long, slender. Var. 

 BoiSSiERi, De Candolle. Leaves larger and more numerously toothed, often 

 over 3 ins. long ; young shoots and leaf-stalks downy. Perhaps intermediate 

 between the two species. Var. PETIOLARIS, De Candolle. Leaf-stalk up to 

 i in. long. Leaves almost entire or toothed towards the apex, and often of 

 large size. 



Q. MACEDONICA, A. De Candolle. MACEDONIAN OAK. 



A small deciduous tree of slender, pyramidal habit when young ; branchlets 

 dull and grey, furnished at first with stellate scurf. Leaves ovate-oblong, slightly 

 heart-shaped at the base, taper-pointed, with nine to eleven parallel veins 

 either side the midrib, each terminating in the apex of a comparatively large, 

 incurved, triangular tooth; i to 2| ins. long, J_to i ins. wide; shining 

 with a rather metallic lustre above, duller beneath ; both surfaces quite 

 smooth by the time the leaf is fully grown ; stalk in. or less long. Acorn 

 usually solitary, scarcely stalked, f to i ins. long. 



Native of S.E. Europe ; introduced about 1890. A very distinct oak, 

 rather stiff in habit and (in a young state at least) retaining its leaves until 

 December. It is very hardy, and I have never seen it injured by frost. As
