Angophora leiocarpa is a species ofthe myrtle family (Myrtaceae). It occurs in east Queensland and in adjacent northeastern New South Wales .

description

Appearance and leaf

Angophora leiocarpa grows as a tree that can reach heights of up to 25 meters. The bark is smooth, pink, gray or cream-colored all over the tree and peeled slightly.

The simple leaves are always opposite to each other on the branches. In angophora leiocarpa is Heterophyllie before, that is, the leaves of a plant differ in their size and shape. The leaves of young specimens are sessile and covered with stiff, simple hair and bristly glandular hairs ( trichomes ). With a length of up to 10 cm and a width of about 1.5 cm, they are broad-lanceolate or narrow-elliptical. On medium-aged specimens, the leaves are straight, entire and dull green. The leaves on adult specimens are divided into petiole and leaf blade. Your petiole is 10 to 15 mm long. Their simple leaf blade is 7 to 14 cm long and 1 to 2.5 cm wide and lanceolate with a pointed base and a pointed upper end. The top and bottom of the leaves are colored differently. The lateral nerves are closely spaced at an obtuse angle to the main nerve. The cotyledons ( cotyledons ) are almost circular.

Inflorescence and flower

At the end of a 15 to 32 mm long, bare inflorescence stem, there are several partial inflorescences in compound inflorescences . The bare or stiffly hairy flower stalk is 4 to 9 mm long. The egg-shaped flower buds are 4 to 7 mm long and have a diameter of 4 to 6 mm. The hermaphrodite flowers are creamy white. The flower cup (hypanthium) is smooth or slightly ribbed. The four sepals are reduced to four calyx teeth on the flower cup. The four petals have a length of 3 to 4 mm and a width of about 3 mm each.

Fruit and seeds

The stalked fruit is egg-shaped with a length of 9 to 13 mm and a diameter of 8 to 11 mm and it often tapers towards the tip. The disc is flat or indented and covered by the edge of the flower cup. The kneecap-shaped seeds are regular and flattened, smooth and silk-matt red.

Occurrence

The main distribution area of Angophora leiocarpa is in eastern Queensland and the adjacent northeast of New South Wales , north of Grafton and Narrabri . Angophora leiocarpa is widespread and distributed locally.

Angophora leiocarpa thrives mainly on deep sandy soils in floodplains or on a sandstone basis .

Taxonomy

It was first described in 1986 by Gregory John Leach under the name ( Basionym ) Angophora costata subsp. leiocarpa L.ASJohnson ex GJLeach under the title A Revision of the Genus Angophora (Myrtaceae) in Telopea , Volume 2 (6), p. 760. The type material has the inscription New South Wales: North Western Slopes: Just S of Warialda, near High School, Leach 423, Aug 25, 1976 (LTB). Isotype: NSW on. The new combination to Angophora leiocarpa (LASJohnson ex GJLeach) KRThiele & Ladiges took place in 1988 by Kevin Richard Thiele and Pauline Yvonne Ladiges under the title A cladistic analysis of Angophora Cav. (Myrtaceae) in Caldistics , Volume 4 (1), p. 41. Other synonyms are Eucalyptus leiocarpa (LASJohnson ex GJLeach) Brooker and Angophora costata subsp. leiocarpa L.ASJohnson ex GJLeach .
