Description
Eucalyptus marginata grows as a tree and can reach heights of growth of up to 40 meters. An estimated an age of 400 to 800 years of Eucalyptus marginata specimen, known as Old Jarrah Tree, Armadale is to find Western Australia. It forms a relatively open canopy. The stem length reaches about half the tree height and trunk diameter of up to 2 meters. The light brown bark is längsgefurcht and coarsely fibrous. The hard heartwood is pink to dark red or red-brown color. The sapwood is narrow, the sapwood is bright and displays the colors of the heartwood. Annual rings are mostly lacking.
The color of the lance-shaped, crescent-shaped leaves varies depending on the subspecies and location.
The white, cream or pink flowers bloom from June to January.
Occurrence
Eucalyptus marginata is widespread in the south-west Western Australia in areas with relatively uniform water supply and an annual rainfall of over 600 mm. You can find the Jarrah in an area of 100 km north of Perth to the south coast. The extensive root system of the tree can survive in a nutrient-poor environment.
System
The first description of Eucalyptus marginata occurred in 1802 in James Edward Smith: Transactions of the Linnean Society of London, 6, p 302 are synonyms for Eucalyptus marginata Donn ex Sm: Eucalyptus floribunda Hugel ex Endl, Eucalyptus mahogani F.Muell. . orth var, Eucalyptus mahoganii F.Muell. , Eucalyptus hypoleuca showers.
From Eucalyptus marginata Donn ex Sm, there are three subspecies:
- Eucalyptus marginata subsp. elegant ella Brooker & Hopper: It is native to Western Australia.
- Eucalyptus marginata Donn ex Sm subsp. marginata: it is up to 40 m high and comes in the South West Botanical Province: Avon front Wheatbelt, Esperance Plains, Geraldton Sand Plains, Jarrah Forest, Mallee, Swan Coastal Plain, Warren.
- Eucalyptus marginata subsp. thalassica Brooker & Hopper: She is 5 to 25 meters high and comes in the South West Botanical Province: Avon front Wheatbelt, Jarrah Forest, Swan Coastal Plain.
Eucalyptus marginata forms with other Eucalyptus species hybrids:
- Eucalyptus marginata × megacarpa: it is up to 8 m high and comes in the South West Botanical Province: before Jarrah Forest, Warren.
- Eucalyptus marginata × pachyloma: it is 1.5 to 5 m high and comes in the South West Botanical Province: Avon front Wheatbelt, Esperance Plains, Jarrah Forest.
- Eucalyptus marginata × buprestium: it is 1, 5-5 m high and comes in the South West Botanical Province: before Esperance Plains.
- Sporadically occur, hybrids between Eucalyptus and Eucalyptus marginata erectifolia.
Use
Through the flowers Jarrah plays in the honey extraction a role, but mainly the wood is utilized. Jarrah is one of the most important hardwoods of Australia. The resistant against termites wood of the jarrah tree is used for the construction of furniture, as parquet floors and for floors.
