Agathis orbicula
species of plant
Agathis orbicula, the Sarawak kauri, is a coniferous tree in the family Araucariaceae, endemic to the island of Borneo. It is found scattered throughout tropical rainforests and Kerangas forests. It is commonly found on hills and plateaus. The species is facing a high risk of extinction due to its scattered distribution and the decline in quality of its habitat.
Description
Agathis orbicula is a medium-sized tree of up to 40 metres (130 ft). Like all Agathis, Sarawak kauri is generally possessed of a large, straight trunk. The trunk is usually branchless until close to the top where branches are retained which form a globular crown.
The leaves range in shape from ovangular to circular, and are glaucous on their underside. The leaves are roughly two by three centimetres; juvenile leaves are much larger by comparison and are roughly twice the size of adult leaves. It can be inferred that the tree is similar in its appearance to other large trees of the genus, particularly Agathis borneensis.
The public source identifies “Agathis orbicula” as species of plant. This brief keeps that definition visible, then builds a research path around Agathis, orbicula and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Agathis orbicula”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q2826483. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
