Description

Appearance and leaf

Eucalyptus caleyi grows as a tree reaching heights of growth of up to 25 meters. The bark remains on the entire tree is gray - black and rough. The bark of young branches is green. Oil glands are in the marrow of the young branches, but not into the bark.

In Eucalyptus caleyi is available Heterophyllie. The leaves are always divided into petiole and leaf blade. In young specimens the leaf blade is ovate to floured round and blue green or frosted. At medium old specimens it is at a length of about 6 cm and also floured a width of about 5 cm ovate to circular, straight, entire, and blue green or frosted. The blue- green floured or frosted leaves in adult specimens with the same color top and bottom sides are at a length of 5 to 10 cm and a width of 1.5 to 4.0 cm lanceolate to ovate, relatively thick, straight, taper towards the Spreitenbasis and have a blunt or rounded upper end. Your petiole is narrow flattened or channel-shaped with a length of 14 to 23 mm. The barely visible lateral nerves go at an acute angle from middle distances from the median nerve. The cotyledons ( cotyledons ) are wrong - kidney-shaped.

End or pendant on a terete at a length of 12 to 20 mm in cross section, or narrow - edged inflorescence stem are about siebenblütige part inflorescences in total composite inflorescences. The terete pedicels are 4-10 mm long. The blue- green floured or frosted flower buds are egg -, club-, short spindle-shaped or square with a length of 6 to 9 mm and a diameter of 4 to 5 mm. The sepals form a calyptra, which drops early. The smooth calyptra conical, shorter than or as long as the smooth flower cup ( hypanthium ) and narrower than this.

System

The first description of Eucalyptus caleyi was made in 1906 by Joseph Maiden The Forest Flora of New South Wales, Volume 2, p 205 The type material has the label " New South Wales, Howell, JH Maiden and JL Boorman, Aug. 1905 ( holo NSW, iso G, K, L ) "on.

From Eucalyptus caleyi Maiden There are two subspecies:

• Eucalyptus caleyi Maiden subsp .. caleyi, syn. Eucalyptus coerulea RTBaker, Eucalyptus leucoxylon var pallens ( Benth. ) Rehder, Eucalyptus sideroxylon var pallens Benth. The flower buds and fruits are not square.
• Eucalyptus caleyi subsp. ovendenii LASJohnson & KDHill: The flower buds and fruits are square.

Natural hybrids between Eucalyptus caleyi were subsp. caleyi and Eucalyptus albens, crebra Eucalyptus, Eucalyptus dealbata, Eucalyptus and Eucalyptus microcarpa Melliodora found.
