Although by some authorities regarded as a variety of P. halepensis, this seems to be a distinct, though closely related, species. The tree is of thin, ungainly habit; its leaves (in pairs) are 4 to 6 in. long, its young shoots are green, and more flexible than in P. halepensis; finally, its cones point forwards instead of backwards, and are thicker (2 in.) at the base. It is rather lacking in attractive qualities, being thin in branch and leaf and inferior in this respect to P. halepensis. It was described by Tenore in 1811 and was said by him to occur wild in western Calabria, though it has not been rediscovered there since. Its main distribution is in Asiatic Turkey and the Near East, as far east as Kurdistan; it also occurs in the Aegean and Cyprus.

P. brutia is rare in cultivation, the only large specimen recorded being one at Kew, which measures 44 × 6 ft (1971).

This species was by some 19th-century botanists confused with P. nigra var. cebennensis under the name P. pyrenaica.

From New Trees

Pinus brutia Ten.

(Subgen. Pinus, Sect. Pinus)

Calabrian Pine, Turkish Pine

Tree to 35 m, trunk straight and slender. Bark thin, flaky, reddish orange, becoming reddish brown, fracturing into plates separated by longitudinal fissures. Crown open and rounded. Branchlets slender, greyish brown; vegetative buds not resinous. Leaves in fascicles of two, persisting for one and a half to two and a half years, bright green or yellowish green, slender, straight and rigid, semicircular in cross-section, 10–18 × <0.1 cm, margins serrulate, apex acute; juvenile leaves glaucous, 1.5–4 cm long, and produced for up to four years; adult leaves first appearing about nine months to two years after germination. Fascicle sheaths 1–1.5 cm long, persistent. Cataphylls subulate, 0.1–0.2 cm long, light to dark brown. Male strobili 1.8 × 0.4 cm. Female cones subterminal, in whorls of three to four or rarely solitary, sessile or pedunculate; cones 5–11(–13) × 5–7 cm, mature in about 24 months, ovoid-conical, green, ripening orange-brown to red-brown in spring. Scales thick, rigid, woody; apophysis 1–1.5 × 1.5–2 cm, rhombic to pentagonal; umbo dorsal, flat or slightly raised. Seeds dark greyish brown; wings 1.5–2 × 1 cm, brown with yellowish streaks. Frankis 1993, 1999, Farjon 2005a. Distribution CYPRUS; GREECE: Crete and east Aegean islands; LEBANON; SYRIA; TURKEY. Pinus brutia is also present (though probably introduced) in Calabria – formerly Brutia – Province in southern Italy. Habitat Grows in a variety of habitats in the eastern Mediterranean, between 10 and 1500 m asl. USDA Hardiness Zone 7. Conservation status Lower Risk. Illustration Farjon 2005a; NT580. Cross-references B215, S373, K210.

There is considerable confusion regarding the infraspecific taxa of Pinus brutia. For example, Yaltirik & Boydak (2000) described var. densifolia from southern Anatolia, which had a dense, compact, spherical crown, but this feature of the habit was probably the result of environmental conditions or fungal infection (see discussion in Frankis 1999). A key to the varieties recognised by Farjon (2001) is presented below.

The cones of one form of P. brutia var. brutia, f. kruepericola Frankis, do not open widely on weathering, so trap the seeds. However, Krüper’s Nuthatch (Sitta krueperi) removes seeds from the cones and distributes them around the forest (Frankis 1992).

var. brutia


P pityusa Stev.

Synonyms
P. halepensis var. pityusa (Stev.) Gord

This interesting conifer occurs along the north-eastern coast of the Black Sea from Anapa to Pitsunda. It is closely related to P. brutia, differing mainly in its shorter leaves.

var. brutia

The typical variety has been considered rare in cultivation and was given a rather sparse description by Bean (1976b). When mature it can be quite an attractive tree, with a broad, rounded crown and many persistent cones thickening the canopy.

var. eldarica (Medw.) Silba

Common Names
Eilar Pine
Afghan Pine
Quetta Pine

Pinus brutia var. eldarica is rare both as a truly wild tree and in cultivation in Europe, where it is grown in only a few collections, but it is widely cultivated in the southwestern United States where it copes well with dry heat and poor soils (Jacobson 1996). As a native tree it is restricted to a small area of Azerbaijan and Georgia, but it is widely naturalised or semi-cultivated across central Asia (Iran, Afghanistan and Pakistan). It has been speculated that it was transported by traders on the Silk Route (Conkle et al. 1988). There are several trees at Kew, grown from seeds received in 1978 from the Forestry Department of Afghanistan, at a time when such peaceable activities as seed-collecting were still possible there. These specimens range between 10 and 12 m in height, and vary slightly in habit, but all have very thick, strongly ridged reddish bark that oozes copious resin. In general the branches are held rather stiffly upright, but one tree has a more rounded outline. The bark peels from the branches in reddish flakes, and this alone makes it a curiously attractive tree. The American stock is also of Afghan origin, collected from the Herat region in the 1960s and distributed by the US Department of Agriculture (Jacobson 1996). Trees sold by Monrovia Nursery under the trademarked selling name Christmas Blue are apparently seedlings from a more glaucous parent tree (Jacobson 1996).

var. pendulifolia Frankis

This variety is in cultivation in Turkey (M. Frankis, pers. comm. 2007), but no trees have been traced in our area since Keith Rushforth’s specimen was killed by Armillaria.

var. pityusa (Steven) Silba

Synonyms
P. brutia var. stankewiczii (Sukacz.) Frankis

Var. pityusa has a limited presence in cultivation, with a few trees scattered through our area. Jacobson (1996) states that in the United States it is very inferior in performance compared to var. brutia and var. eldarica, and is seldom seen. In the United Kingdom the best example is probably one of several at the Sir Harold Hillier Gardens, measured at 8.1 m in 2008 (Sir Harold Hillier Gardens database). These were grown from seed collected in the former USSR for the French seed company Versepuy, received in 1985. Given the number of varieties of P. brutia, confirmation of identity probably requires reliable knowledge of provenance. Ukrainian material is sometimes distinguished as var. stankewiczii, on the basis of some electrophoretic characters (Conkle et al. 1988, Frankis 1993), but no specimens of Ukrainian origin are currently known to be in cultivation in our area (M. Frankis, pers. comm. 2007).
