Synonyms: Eucalyptus acuminata; Eucalyptus camaldulensis acuminata; Eucalyptus camaldulensis brevirostris; Eucalyptus rostrata acuminata; Eucalyptus rostrata brevirostris; Eucalyptus subulata; Eucalyptus tereticornis rostrata The River Red Gum (Eucalyptus camaldulensis) is a tree of the genus Eucalyptus. It is one of around 800 in the genus. It is a plantation species in many parts of the world, but is native to Australia, where it is widespread, especially beside inland water courses. Oddly, it is named for a private estate garden near the Camaldoli monastery near Naples, from where the first specimen came to be described. |

In large doses, oil of eucalyptus, like so many essential oils has caused fatalities from intestinal irritation; Death is reported from ingestion of 4 - 24 ml of essential oils, but recoveries are also reported for the same amount; Symptoms include gastroenteric burning and irritation, nausea, vomiting, diarrhoea, oxygen deficiency, ,weakness, dizziness, stupor, difficult respiration, delirium, paralysis, convulsions, and death, usually due to respiratory failure; | | Janka Hardness [4] | 2180 lbf (989 kgf) Hard | | Leaf Type [3] | Evergreen | | Lifespan [2] | Perennial | | Pollinators [3] | Bees | | Propagation [2] | Bare Root, Container, Seed | | Root Depth [2] | 20 inches (51 cm) | | Seed Spread Rate [2] | Slow | | Seed Vigor [2] | High | | Seeds Per [2] | 2628384 / lb (5794599 / kg) | | Shape/Orientation [2] | Erect | | Structure [3] | Tree | | Usage [3] | A gum is obtained from the plant. It is used medicinally and in tanning;
The leaves contain 0.1 - 0.4% essential oil, 77% of which is cineol There is some cuminal, phellandrene, aromadendren (or aromadendral), and some valerylaldehyde, geraniol, cymene, and phellandral;
The leaves contain 5 - 11% tannin. The kino contains 45% kinotannic acid as well as kino red, a glycoside, catechol, and pyrocatechol; The leaves and fruits test positive for flavonoids and sterols; The bark contains 2.5 - 16% tannin, the wood 2 - 14%, and the kino 46.2 - 76.7%;
A fast growing tree with wide-ranging roots, it can be planted in soil stabilization schemes and can also be planted in marshy land where it will help in draining the land, thereby destroying a potential breeding site for mosquitoes; It is planted in S. Italy for this purpose.
The wood, durable, easy to saw, yet resistant to termites, is widely used in Australia for strong durable construction, interior finish, flooring, cabinetry, furniture, fence posts, cross-ties, sometimes pulpwood; Australian aborigines made canoes from the bark; According to NAS (1980a), annual wood yields are around 20 - 25 m3/ha in Argentina, 30 m3 from Israel, 17 - 20 from Turkey in the first rotation, and 25 - 30 in subsequent coppice rotations; On poor arid sites yields are only 2 - 11 m3 on 14 or 15 year rotations; | | Vegetative Spread Rate [2] | None |
