Dalbergia lanceolaria

Dalbergia lanceolaria is a species of tree in the subfamily Faboideae and tribe Dalbergieae.[2] It is a medium-sized tree growing to 20m tall[3][4] and is native to: India, Sri Lanka, Nepal, Burma[4] and Indo-China (its Vietnamese names are bạt ong or trắc múi giáo).[3]

Dalbergia lanceolaria
Scientific classification
Kingdom: Plantae
Clade: Tracheophytes
Clade: Angiosperms
Clade: Eudicots
Clade: Rosids
Order: Fabales
Family: Fabaceae
Genus: Dalbergia
Species:
D. lanceolaria
Binomial name
Dalbergia lanceolaria
Synonyms[1]
  • Amerimnon lanceolarium (L.f.) Kuntze
  • Dalbergia arborea B.Heyne
  • Dalbergia frondosa DC.

The bark of the tree is traditionally used as an analgesic and anti-diarrhoeal.[5] The apiose isoflavone compound lanceolarin is found in its root bark.[6]

Because it produces new stems (ramets), it is recommended for reforestation projects on degraded land where seeds are unlikely to grow successfully.[7]

Subspecies

The Plant List includes:[1]

  • D. lanceolaria var. maymyensis (W. G. Craib) Thoth.
  • D. lanceolaria subsp. paniculata (Roxb.) Thoth. - synonym D. nigrescens (Vietnamese: quành quạch, trắc đen)
gollark: I *will* continue use of `they`, for general convenience and the ability to conveniently ignore gender entirely.
gollark: Your criticism², while interesting, ultimately fails. Consider: you have *responded* to my criticism [see screenshot], despite claiming that this would not occur. This is an evident contradiction.It is also clear that, contra to your original claim #2, gollariosity has *increased* as a result of your actions.
gollark: I wholeheartedly disagree with removal of apioderivative words.1. This is dubious. Current research suggests nonlinear apioformic effects, where high use of apio-derived words leads to increased use due to memetic contamination, rather than a conserved/fixed level of apiodensity.2. I am, in any case, inevitable. Additionally, I do not consider this good.3. This appears to contradict #1 somewhat. We have also proven unable to displace the "apioform"/"bee" meme, despite previous attempts. If you want to remove it, come up with better memetics.
gollark: Wrong.
gollark: Did you know? There have been many incidents in the past where improper apiary safety protocols have lead to unbounded tetrational apiogenesis, also referred to as a VK-class "universal apiary" scenario. Often, the fallout from this needs to be cleaned up by moving all sentient entities into identical simulated universes, save for the incident occurring. This is known as "retroactive continuity", and modern apiaries' safety systems provide this functionality automatically.
