Turkey Oak Leaf Identification: American and European

Turkey oak leaf identification starts with location, because two different oaks share the name. In the southeastern United States, turkey oak is Quercus laevis, a small red oak of dry sandhills whose deeply cut leaves are said to resemble a turkey's foot. In Britain and Europe, turkey oak is Quercus cerris, a large tree native to southern and southeastern Europe and Asia Minor, named for Turkey and introduced to UK woodlands in the 18th century (Woodland Trust, Wikipedia).

• Southeastern US, sandy pine woods - Quercus laevis.
• UK, Europe, parks and estates - Quercus cerris.

The two are told apart from each other and from their neighbours in different ways, so each gets its own section below.

• Size and lobes - NC State Extension gives 4 to 8 in long with 3 to 7 bristle-tipped lobes. Wikipedia gives a typical 10 to 17 cm, occasionally 8 to 30 cm, with slender lobes cut deeply apart, each ending in 1 to 3 bristle teeth.
• How it hangs - NC State describes leaves hanging perpendicular to the ground, turned on edge, which is the easiest field mark from a distance.
• Colour - shiny green above, paler below with a few red hairs along the midvein; fall colour red to red-orange, often lasting well into winter (NC State).
• Bark - dark gray to black, deeply furrowed with irregular ridges, reddish inner bark (NC State).
• Acorns - about 1 in long (NC State; Wikipedia gives 20 to 25 mm), with a thin reddish-brown cap of fuzzy scales covering about a third of the nut; they mature in the second year, September to October.
• Size and habitat - a small tree: 30 to 40 ft (NC State), 15 to 30 ft in Florida landscapes (UF/IFAS), typically 8 to 10 m (Wikipedia). It grows from Virginia to Florida and west to Louisiana on poor, dry, sandy or rocky soils, often under longleaf pine (Wikipedia).

• Leaf - 7 to 14 cm long and 3 to 5 cm wide, with 6 to 12 triangular lobes on each side (Wikipedia). The Woodland Trust stresses that the shape varies: some leaves have elaborate pointed lobes, others simple rounded ones. The leaf is rough and thick, shiny above and felted underneath.
• Buds - in clusters, with bud scales that extend beyond the bud, giving a whiskery look (Woodland Trust); Wikipedia describes soft bristles around the buds.
• Acorn cup - the clearest feature: the cup is about 2 cm deep and densely covered in soft, mossy bristles 4 to 8 mm long (Wikipedia), like a hat made of moss (Woodland Trust).
• Acorn - 2.5 to 4 cm long, orange at the base grading to a green-brown tip, maturing about 18 months after pollination (Wikipedia).
• Bark - dark gray, with plates and deep fissures, often streaked orange near the base on mature trees (Woodland Trust, Wikipedia).
• Size - a large tree, 25 to 40 m tall (Wikipedia).

In Britain the comparison that matters is Quercus cerris against the native English oak, Quercus robur. From the Woodland Trust's species pages:

• Leaf stalk and lobes - English oak leaves are about 10 cm long with 4 to 5 deep, smooth-edged rounded lobes and almost no stalk. Turkey oak leaves carry more lobes, 6 to 12 a side per Wikipedia, often pointed, and are rough above and felted beneath.
• Buds - both have clustered buds, but turkey oak's bud scales stretch out beyond the bud into whiskers.
• Acorns - English oak acorns are 2 to 2.5 cm on long stalks in a plain scaly cup. Turkey oak acorns sit in the unmistakable mossy cup.

If you find a mossy cup under the tree, it is turkey oak.

In North America the useful comparison is Quercus laevis against northern red oak, Quercus rubra. Both are in the red oak group, so both have bristle-tipped lobes and acorns that take two seasons to mature.

• Lobes - northern red oak has 7 to 11 bristle-tipped lobes on a leaf 5 to 8 in long, very uniform in shape (Virginia Tech). Turkey oak has fewer, 3 to 7, and they are slender and cut deeply apart (NC State, Wikipedia).
• How the leaf hangs - turkey oak leaves hang on edge, perpendicular to the ground; northern red oak leaves do not.
• Acorn - northern red oak's is 3/4 to 1 in, nearly round, with a flat, thick cap covering about a quarter or less (Virginia Tech). Turkey oak's cap is thin, with fuzzy scales, covering about a third (NC State).
• Habitat - turkey oak grows on dry sandhills where, Wikipedia notes, few oaks other than blackjack oak can thrive.

Quercus laevis. NC State Extension says the wood is used for fuel or rough construction and that the tree is a larval host for several butterflies. UF/IFAS notes an abundant acorn crop eaten by squirrels, deer and wild turkeys, and says established trees are drought tolerant and suit many home landscapes. Wikipedia's point is that it grows on infertile, dry, sandy sites where other oaks fail.

Quercus cerris. The Woodland Trust says its timber has a fairly poor reputation, especially outdoors because it does not weather well; it was used for wainscoting and makes firewood once seasoned. Wikipedia says its tendency to crack confines it to uses such as fencing. It also hosts the knopper gall wasp, Andricus quercuscalicis, whose larvae damage the acorns of native British oaks, and the Woodland Trust rates it less valuable to native wildlife than English or sessile oak. Wikipedia records a 1998 Ministry of Defence order to fell turkey oaks on UK bases for that reason, and notes a well-known hybrid with cork oak, the Lucombe oak, raised in Exeter around 1762.

WoodLens identifies both turkey oaks from a leaf, the bark or an acorn. Photograph the upper side and underside of a leaf, and an acorn cup if you can find one.
