A deciduous tree attaining the same size as the common oak, Q. robur, and not differing in its bark; it differs in its habit, having straighter branches and a trunk that usually penetrates further into the crown than is the case with the common oak; buds usually rather more elongated and acute at the apex. Leaves broadest at or only slightly above the middle, hence not so markedly obovate or oblanceolate as in Q. robur and less tapered to the base, which is cuneate or cordate and lacks the auricles characteristic of the common oak; the texture is usually somewhat firmer, the upper surface rather more glossy, and the underside has persistent hairs on the midrib and main veins and sometimes scattered stellate hairs on the surface of the blade; intercalary veins, i.e., veins running out to the sinuses between the lobes, are much less frequent than in Q. robur, and the lobing is more regular; the stalk, very short in the common oak, is 38 to 114 in. long in the durmast oak. Female flowers with almost sessile stigmas (styles usually well developed in Q. robur). The common name ‘sessile oak’ refers to the fruits, which are borne directly on the twig and not on a long slender peduncle as in Q. robur. The scales of the acorn-cup are rather more numerous and more closely imbricated than in Q. robur.

The general distribution of Q. petraea is similar to that of Q. robur, with the notable difference that it does not extend so far to the east on the Continent. In the British Isles the durmast oak avoids the heavy clay soils of the Weald and the Midland Plain but is the commoner species on siliceous soils in the north and west, and is also to be found on light, non-calcareous soils in southern England, often in association with the common oak.

The fine tree at Whitfield, Herefordshire, mentioned in previous editions, still exists and measures 135 × 1414 ft (1963). Others measured recently are: Oakley Park, Shrops., 111 × 2214 ft and 85 × 2314 ft (1971); Nettlecombe, Som., 112 × 2134 ft and 95 × 23 ft (1959); Shobdon, Heref., about 90 × 30 ft (1973); Croft Castle, Heref., 50 × 2612 ft (1960); Knole Park, Kent, 130 × 1712 ft (1969).

On the Continent, the durmast oak comes into leaf and flowers up to two weeks later than the common oak and hybrids between them are therefore by no means common. It is said, however, that in the British Isles there is less difference in flowering time and that hybrids are commoner in consequence. However, both species are variable and minor deviations from the norm are sometimes wrongly taken to be the result of hybridity. For example, the fruits in the durmast oak are sometimes borne on peduncles, but in such cases the peduncle is thick at the base, where it resembles a normal twig. True hybrids, for which the correct name is Q. × rosacea Bechstein, would show such combinations as auricled leaves, downy beneath, on stalks of intermediate length; or pedunculate acorns, leaves almost glabrous beneath but not auriculate, etc.

The durmast oak has not been so prolific of varieties as Q. robur, but most of the following are or have been in cultivation at Kew:

From the Supplement (Vol. V)

specimens: Knole Park, Kent, 118 × 1914 ft (1984); Lullingstone Park, Kent, 82 × 2914 ft at 4 ft (1982); Cowdray Park, Sussex, near Polo Lawn, 105 × 25 ft, 92 × 2434 ft and 98 × 2212 ft (1982–4); Mickleham, Surrey, Sandwith Lane, 100 × 20 ft (1984); Woburn Abbey, Beds., Pleasure Gardens, 80 × 22 ft (1977); Tottenham House, Wilts., Savernake Forest, 100 × 1914 ft (1977); Whitfield, Heref., a fine tree mentioned in earlier editions of this work and by Elwes and Henry, 141 × 1514 ft and another two 111 × 1812 ft and 105 × 1514 ft (1984); Easthampton Farm, Shobdon, Heref., an exceptionally fine tree, 82 × 3214 ft (1985); Brockhampton Park, Heref., 95 × 23 ft (1978); Croft Castle, Heref., 115 × 2434 ft and 65 × 2712 ft at 3 ft (1984); Nettlecombe, Som., 80 × 2112 ft and 118 × 24 ft (1984); Oakley Park, Shrops., 111 × 2214 ft and 85 × 2314 ft (1971); Powis Castle, Powys, called ‘The Giant’, 70 × 3514 ft (1984); Munches, Kirkcud., 121 × 1914 ft (1985); Drumlanrig Castle, Dumfr., 105 × 2114 ft (1984).

cv. ‘Columna’. – Although usually listed under Q. petraea, this is probably a hybrid between Q. petraea ‘Muscaviensis’ and Q. robur f. fastigiata. ×

f. mespilifolia – There are two examples of this interesting variant at Kew, in oak planting west of Broad Walk, 69 × 714 ft (1973) and in Oak Collection, pl. 1871, 75 × 612 ft (1978); and another of 80 × 934 ft in the University Botanic Garden, Leicester (1985).

Q. × rosacea – Mentioned on page 500, this hybrid between Q. petraea and Q. robur is represented by a specimen of 70 × 414 ft in the Edinburgh Botanic Garden (1985). Natural occurrences of the cross are studied by B. S. Rushton in Watsonia, Vol. 12, pp. 81–101, 209–24 and 315–24 (1978).


Leaves oval or obovate, with shallower lobes than the type. Fruits with a distinct stalk as much as {1/2} in. long. It was distributed by Booth’s Flottbeck Nurseries, Hamburg, around the middle of the last century. It is unlikely to have come from Afghanistan, as they claimed. There are three examples at Kew, the largest 85 × 7{3/4} ft (1971).


Leaves decurved at the margin, so that the centre is humped or hooded. The tree at Kew, planted in 1871, has mostly reverted.


Of columnar habit, with rather narrow and elongated, sparsely and irregularly lobed leaves. Put into commerce by Messrs Hesse of Weener, Hanover, shortly before the second world war.

f. mespilifolia (Wallr.) Rehd

Leaves lanceolate to narrowly oblong, up to 5 in. long, 1 in. wide, tapered at both ends, sinuately lobed to almost entire. It occurs occasionally in the wild, and was described by Wallroth, as Q. robur var. mespilifolia from a tree found in the Harzgebirge. The garden variety ‘Louettei’ is of this nature, but is of rather pendulous habit. In the very similar f. sublobata (Kit.) Schneid., the leaves are more lobed, but still unusually long and narrow. Here belongs the garden variety ‘Geltowiensis’, distributed by the Royal Nurseries at Geltow near Potsdam.There are two specimens of f. mespilifolia at Kew, the larger, on Palace Lawn, measuring 72 × 7 ft (1970).


According to the original description this had short, serrated leaves resembling those of Q. cerris. They are very downy beneath. It was discovered near Falkenberg near Hamburg and was put into commerce by Booth’s Flottbeck Nurseries in 1837.


Leaves long and narrow, entire or unequally lobed. Put into commerce by Späath towards the end of the last century.


Leaves very long and narrow, with irregular, slender, forward-pointing lobes, some leaves reduced almost to threads. Leaves on the Lammas growths more or less normal. It was originally named Q. sessiliflora laciniata, a name used much earlier by Lamarck and de Candolle for a wild form with deeply lobed leaves.


Leaves of first growth often nearly or quite entire, those of the second or July growth nearer the type and lobed.


Branches very pendulous, forming an umbrella-shaped crown. Raised in France around 1867 in the garden of the Military Hospital, Vincennes, and propagated by grafting.

Q dalechampii Ten.

Q. lanuginosa subsp. dalechampii (Ten.) Camus
Q. robur subsp. sessiliflora var. tenorei A. DC

A poorly defined species which has been very variously interpreted by botanists. It appears to be intermediate between Q. petraea and Q. pubescens, and is possibly the result of past hybridisation between them. According to Mme Camus it is confined to Italy (mainly the south). Dr Schwarz, who gives a description greatly at variance with hers, attributes to it a wider range.

Q iberica Bieb

Very closely allied to Q. petraea. Leaves with up to eight or even ten pairs of lobes, usually with rather large axillary tufts of hairs beneath. Fruits on a short peduncle. Native of Transcaucasia, said to be common around Batum.

Q mas Thore

This is recognised as a distinct species by Dr Schwarz, but Mme Camus doubted whether it was really any more than a local variant possibly meriting the rank of subspecies. The leaves are rather larger than in Q. petraea, with up to ten pairs of narrowish, forward-pointing lobes; the fruit peduncles are silky hairy. Pyrenees and N. Spain.


Young leaves reddish purple. The same or a similar variety is known as ‘Purpurea’.
