Eucalyptus Dalrymple

In nature, the species range covers Tasmania and southeastern Australia . Widely distributed in cold and humid mountains at an altitude of 900 to 1200 m above sea level. m. in the central and southern parts of New South Wales , on Delegate Mountain in Victoria and Tasmania.

It forms pure plantings, but more often grows together with Eucalyptus delegatensis and Eucalyptus malifloriforum with undergrowth from Acacia blackwood and Acacia silvery .

Differs in high frost resistance; withstands short-term temperature drops of -12 ... -11 ° C without damage.

It grows rapidly, especially at a young age and on favorable soils. So, in 4.5 years, on deep, spread, moderately moist soil, it reaches an average height of 15.5 m (individual trees 18.5 m), with a trunk diameter of 13-15 cm. In 15 years, under the same conditions, it grows to 25–27 m, with a trunk diameter of 40–50 cm. It develops worse on clay slopes: over 4 years it grows on average here with trees 8.5 meters high, with a trunk diameter of 8 cm. It grows slowly on podzolized-carbonate soils: over 4 , 5 years reaches a height of only 3.5 m, with a trunk diameter of 3 cm.

A tree up to 45 m high, with a trunk diameter of up to 1.5, less often up to 2.7 m.

The bark is smooth, falling, white, with age it turns pink with bluish stripes and spots, in the lower part of the trunk more or less rough and not falling.

Young leaves are opposite, in a large number of pairs, sessile, bluish, ovate, heart-shaped or rounded, 4-6 cm long, 4-5 cm wide or slightly larger. Intermediate leaves are also opposite, petiolate , ovate or ovate-lanceolate, vary in size and degree of blue color. Adults - alternating, long-grained, from narrowly lanceolate to widely lanceolate, 10-22 cm long, 1.5-2.5 (up to 4) cm wide, dark green, shiny.

Umbrellas are axillary , three-flowered ; legs are compressed or almost cylindrical, 4-7 mm long; buds on pedicels or sessile, from ovoid to cylindrical, 7-8 mm long, 3-5 mm in diameter; the cap is blunt-conical, equal in length to the receptacle tube; anthers open with longitudinal slots; small piece of iron on the back of the anther.

Fruits on legs or sessile, from ovoid-truncated to spherical, 7-8 mm long, 8-9 mm in diameter; the disk is convex or almost flat; valves deltoid, protruding.

Blossoms in the homeland in March - May; on the Black Sea coast of the Caucasus - in April - July.

The wood is pink, light, moderately hard, relatively durable and stable, with well-noticeable annual layers and straight fibers, but is prone to warping and cracking. It is used in paper production, on handles for tools, on poles, boxes, etc.

Leaves contain essential (eucalyptus) oil (0.48%), consisting of cineole (50%), pinene , esters and sesquiterpenes .
