Dalbergia cochinchinensis
species of plant

Dalbergia cochinchinensis, the Thailand rosewood, Siamese rosewood, or tracwood, (Thai: พะยูง: Phayung; Vietnamese: Trắc (or Cẩm lai nam bộ); Khmer: ក្រញូង: Kranhung; Lao: ກະຍູງ: Kayung; Chinese: 酸枝木: Suān zhī mù ) is a species of legume in the family Fabaceae.
It is a tree yielding valuable hardwood found in Cambodia, Laos, Thailand, and Vietnam. In 2022 its status was re-evaluated as Critically Endangered caused by illegal logging and smuggling. Conservationists project that the species could be extinct within 10 years (by 2026).
Due to its pioneering characteristics, drought tolerance, and nitrogen-fixing ability, it shows potential for restoring degraded forests and deforested sites. Therefore, sustainable plantation of the tree can serve both goals of conservation and forest landscape restoration.
University of Oxford published the transcriptomes of Dalbergia cochinchinensis and five other Dalbergia spp. It was found that D. cochinchinensis had fewer R genes than the co-occurring Dalbergia oliveri.
Demand side: China
The demand for furniture made from Siamese rosewood, chiefly in China where it is known as Hongmu, has led to an epidemic of illegal logging and trafficking, threatening the species with extinction and resulting in a war with poachers. In 2015 seven Thai forest rangers were killed trying to shut down illegal Siamese rosewood logging.
This brief starts where responsible research should: with the source description of “Dalbergia cochinchinensis” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q1930232. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2022, 2026 and 2015.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
