THE False guaiac (Acacia spirorbis) is a tree endemic to New Caledonia (New Caledonia is an archipelago of Oceania in the Pacific Ocean…). However, it is also found on the east coast of Australia (Australia (officially the Commonwealth of Australia) is a country of…).
Description
False guaiac is a shrub, sometimes a tree, that can reach a height of 10 m. The trunk (A trunk can be:) is short and often twisted. Its diameter (for a circle or a sphere, the diameter is a line segment passing through the center…) rarely exceeds 40 cm. The branches are numerous.
The bark, which is approximately 1.5 cm thick, is brown, hard and very cracked.
The fine, olive-green foliage consists of elongated phyllodes (no leaves) 6 to 12 cm long and 0.5 to 1.5 cm wide, which are curved at the end.
The yellow flowers are grouped on inflorescences in spikes about 5 cm long, which are located axillary to the young leaves.
The fruits are pods rolled into a circle or semicircle. They contain some brown, flat seeds measuring 2 × 3 mm.
Two subspecies are recognized:
- Acacia spirorbis subsp. solandri (Benth.)Pedley (identified on the Australian east coast) [1]
- Acacia spirorbis subsp. Spirorbis Benth. [2]
Used
Its wood is beige-brown, a little orange or brown. It is hard and resistant to decay pathogens. It is used for logs and firewood.
False guaiac, due to its great adaptability, has been successfully used to rehabilitate mining areas along with ironwood (Iron is a chemical element with the symbol Fe and atomic number 26. It is the…) (Casuarina collina). It also serves as a host plant that is parasitized by sandalwood (Santalum austrocaledonicum).

distribution
This species (in biological sciences the species (from Latin “species”, “type”…)) is widespread throughout New Caledonia on all soil types, with a preference for the alluvium of ultamafic areas.
It is a gregarious species, often growing in pure stands, commonly found in sclerophyll formations, and common in Niaoulis in scrub, thicket and savannah.
It is resistant to fires, which are particularly common in these formations. In addition, these fires favor its spread: the germination of seeds would be stimulated by the heat (in common usage the words heat and temperature often have the same meaning:…).
