Description
Appearance and leaf
Corymbia aparrerinja grows as a tree reaching heights of growth to 15 or 20 meters. He forms a Lignotuber. The bark is smooth on the whole tree, powdery or matte white or gray and peels in short strips or small, polygonal patches. In the marrow and in the bark oil glands are present.
In Corymbia aparrerinja is available Heterophyllie. The leaves are always divided into petiole and leaf blade. The leaf blade of young specimens is at a length of 3 to 15,5 cm and a width of 2 to 6.5 cm lanceolate to ovate and has stiff glandular hairs. The leaf blade to middle-aged plants is lanceolate to elliptic, straight, entire, and dull green. The petiole of adult specimens is narrow flattened or channel-shaped with a length of 0.5 to 2.5 cm. The leaf blade of adult specimens is relatively thin, with a length of 5 to 16,5 cm and a width of 0.7 to 3.2 cm linear to narrow - lanceolate, straight, cut with tapered Spreitenbasis and pointed top. Your upper leaf surface and bottom is evenly colored glossy green or gray-green. The barely visible lateral nerves go at small distances from an acute or obtuse angle from the midrib. On each half of the sheet, there is a strong, consistent, so-called intra- marginal nerve; he runs along at a short distance on the leaf margin. The cotyledons ( cotyledons ) are nearly circular.
Inflorescence and flower
On a terete, with a length of up to 4 mm in cross section inflorescence stem is a simple or compound inflorescence consisting of doldigen partial inflorescences, each with about seven to eleven flowers. The peduncle is terete with a length of 2 to 5 mm in cross section.
The non- blue-green floured or frosted flower bud is oval to club-shaped with a length of 6 to 7 mm and a diameter of 5 to 6 mm. The sepals form a calyptra, which drops early. The smooth calyptra is knee disc-shaped or hemispherical and as wide as the smooth flower cup ( hypanthium ). The flowers are white or cream-colored.
