description
Appearance and leaf
Corymbia aparrerinja grows as a tree that can reach heights of up to 15 or 20 meters. It forms a lignotuber . The bark is smooth, powdery or matt white or gray all over the tree and peels in short strips or small, polygonal patches. There are oil glands in the pith and in the bark.
In Corymbia aparrerinja there is heterophyllia . The leaves are always divided into a petiole and a leaf blade. The leaf blade on young specimens is lanceolate to ovate with a length of 3 to 15.5 centimeters and a width of 2 to 6.5 centimeters and has stiff glandular hairs. The leaf blade on medium-old plants is lanceolate to elliptical, straight, entire and dull green. The petiole on adult specimens is narrowly flattened or channel-shaped with a length of 0.5 to 2.5 centimeters. The leaf blade on adult specimens is relatively thin, with a length of 5 to 16.5 centimeters and a width of 0.7 to 3.2 centimeters linear to narrow-lanceolate, straight, with a tapering blade base and a pointed upper end. The top and bottom of the leaves are evenly colored shiny green or gray-green. The side nerves, which are barely recognizable, branch off from the median nerve at small intervals at an acute or obtuse angle. On each half of the leaf there is a pronounced, continuous, so-called intramarginal nerve; it runs at a small distance along the edge of the leaf. The cotyledons ( cotyledons ) are almost circular.
Inflorescence and flower
On an inflorescence stem with a length of up to 4 millimeters in cross section stands a simple or compound inflorescence , which consists of doldy partial inflorescences each with about seven to eleven flowers. The flower stalk is 2 to 5 millimeters long in cross section with a round stem.
The not blue-green floured or frosted flower bud is egg-shaped to club-shaped with a length of 6 to 7 millimeters and a diameter of 5 to 6 millimeters. The sepals form a calyptra that falls off early. The smooth calyptra is kneecap-shaped or hemispherical and as wide as the smooth flower cup (hypanthium). The flowers are white or cream in color.
Fruit and seeds
The fruit stalk is 2 to 6 millimeters long. With a length of 9 to 13 millimeters and a diameter of 7 to 9 millimeters, the fruit is cylindrical to ovoid and triple. The disc is indented, the fruit compartments are enclosed or are at the level of the edge.
The regular and flattened, kneecap-shaped or egg-shaped seed with a length of 4 to 6 millimeters has a net-like, matt to silk-matt, red or red-brown seed coat . The hilum is at the top of the seed.
Occurrence
The main distribution area of Corymbia aparrerinja is the southern Northern Territory and the adjoining, extreme east of Western Australia . Also in the northern Northern Territory and western Queensland are found corymbia aparrerinja .
Corymbia aparrerinja prefers to grow in dry areas, on rocky slopes, in dry river beds and on red sand plains.
Taxonomy
The first description of corymbia aparrerinja took place in 1995 by Kenneth D. Hill and Lawrence Alexander Sidney Johnson , entitled Systematic studies in the eucalypts, 7. A revision of the blood woods, genus Corymbia (Myrtaceae) in Telopea , Volume 6 (2-3) P. 453. The type material has the inscription “ Northern Territory: Gosse Range, SWMcDonnell Ranges, H. Basedow, May 1925 (holo: NSW 10075). " on. The specific epithet aparrerinja is derived from the language of the Aborigines . Synonym for Corymbia aparrerinja K.D. Hill & LASJohnson is Eucalyptus aparrerinja (KDHill & LASJohnson) Brooker .
