Help us find the Angle-stemmed myrtle (Gossia Gonoclada)

The Angle-stemmed myrtle (Gossia gonoclada) is an endangered native tree that grows in riverine rainforest areas. Around 73 known trees grow in Logan and Brisbane. Endemic to our region, it grows nowhere else in the world.

Protecting the Angle-stemmed myrtle

Our Gossia gonoclada recovery plan 2019 to 2029 (PDF 2.5 MB) will help protect the endangered Angle-stemmed myrtle. This plan aims to conserve tree populations in Logan and ensure their long-term viability.

Gossia gonoclada is also protected under state and federal legislation, including the Nature Conservation Act (NCA) 1992 and the Environment Protection and Biodiversity Conservation Act (EPBC) 1999. Taking any Gossia gonoclada plant is prohibited under these acts.

Unripe fruit, in its early stages is paler, and greener in colour..

Later stage ripened fruit is less glossy, purpler and may split

Fruit in later stages

In its later stages the fruit appears less glossy and may split.

Telling it apart

It’s easy to mistake the Angle-stemmed myrtle for another common plant called Lilly pilly (Syzygium australe).

When young it can also be mistaken for weeds like Brazilian cherry (Eugenia uniflora).

Lilly pilly flower is fluffier and looks different to the Angle-stemmed myrtle

Lilly pilly flower (Syzygium australe)

The white flower of the Lilly pilly is easily confused for the Angle-stemmed myrtle.

Brazilian Cherry flower looks simiarl tot he angle-stemmed-myrtle, but petals are a different shape

Brazilian cherry flower (Eugenia uniflora)

The Brazilian cherry flower looks similar to the Angle-stemmed myrtle flower.

The bark of the Lilly Pilly is smoother than the angle-stemmed myrtle, with less ridges

The bark of the Lilly pilly is visibly smoother than the Angle-stemmed myrtle, with less ridges.
