Continuing our series, thanks to Steve Thomas from Friends of ACT Trees, this article
concludes the notes on Casuarinas. It is about the genus Allocasuarina.
covers a small number of species which have some interesting characteristics:
- Allocasuarina torulosa - the tallest species
- Allocasuarina decainsneana - the Desert oak, named after a Belgian botaist who never visited Australia!
- Allocasuarina luehmannii - the hardest commercial wood in the world, as measured by the Janka hardness test.
- Allocasuarina littoralis - named from material collected by Banks and Solander at Botany Bay, hence the name.
- Allocasuarina verticillata - planted in the Arboretum at Forest 100 (Friends' Forest) to provide food for the glossy black cockatoos.
- Allocasuarina inophloia - has a hairy bark.
- Allocasuarina grevilleoides - the smallest specia growing to only 0.3m in WA.
Steve has also put together a spreadsheet of all the species in the flora of Australia which shows the species, common name, maximum recorded height and geographical location. What a wonderful resource!
