Allocasuarina inophloia is a species of the genus Allocasuarina in the Casuarina family (Casuarinaceae). It is native to eastern Australia and is called Stringybark She-oak or Woolly Oak there. It can be easily distinguished from all other Allocasuarina speciesby its frayed trunkbark.
description
Vegetative characteristics
Allocasuarina inophloia grows as a small evergreen tree that can reach heights of 3 to 10 meters. The spread treetop is open. The bark is finely elongated in the lower trunk area.
The hanging or straight branches are up to 21 centimeters long and consist of smooth segments that are 4 to 7 millimeters long and 0.5 to 0.6 millimeters thick. The twigs take over the function of the leaves and are also known as phyllodes . On each segment of the branches there are seven to nine reduced, tooth-like to slightly rounded leaves that are 0.3 to 0.5 millimeters long. These leaves are arranged in whorls and do not overlap.
Generative characteristics
The flowering time is in winter. Allocasuarina inophloia is dioeciously segregated ( diocesan ). Long 2 to 4 centimeters ährigen , male inflorescences are at a 0.3 to 0.8 centimeter long inflorescence stem and have 7 to 14 Blütenwirtel on per centimeter. The stamens are 0.5 to 0.8 millimeters long. The female flowers are red. The cone-like inflorescences, which can stand on a 0.3 to 0.8 centimeter long inflorescence stem, are cylindrical in shape with a length of 1 to 2 centimeters and a diameter of 0.9 to 1.2 centimeters; their surface is densely hairy. As diaspores , dark brown wing nuts are formed that are 0.5 to 0.6 centimeters long.
Chromosome number
The number of chromosomes is 2n = 24.
Occurrence
The natural range of Allocasuarina inophloia is in eastern Australia. There the distribution area extends from the Herberton in northern Queensland south to Warialda in northeastern New South Wales .
Allocasuarina inophloia grows in forests as well as in bushland, on soils which have formed on ferrous sediments, laterite or sandstone . Allocasuarina inophloia often grows in association with eucalyptus ( Eucalyptus spec.) And grass trees ( Xanthorrhea spec.). In the bushland, Allocasuarina inophloia occurs alongside various grass tree species also in association with Allocasuarina brachystachya , Acacia williamsiana , Calytrix tetragona , Leucopogon neo-anglicus , Eucalyptus caleyi and Micromyrtus grandis .
Taxonomy
The first description as Casuarina inophloia was in 1882 by Ferdinand von Mueller and Frederick Manson Bailey in Chemist and Druggist , Volume 4, Page 92. The new combination to Allocasuarina inophloia (F. Muell. & FMBailey) LAS Johnson was 1982 by Lawrence Alexander Sidney Johnson in Journal of the Adelaide Botanic Gardens , Volume 6, Number 1, Page 76.
