Dalbergia oliveri[4]is a species oflegumein the familyFabaceaewhich grows in tree form to 15 – 30 meters in height (up to 100 ft.). The fruit is a green pod containing one to two seeds which turn brown to black when ripe. It is threatened byhabitat lossandover-harvestingfor its valuable red "rosewood" timber.
University of Oxfordpublished the transcriptomes ofDalbergia oliveriand five otherDalbergiaspp.[5]It was found thatD. oliverihad moreR genesthan the co-occurringDalbergia cochinchinensis.
Distribution naming and synonyms
[edit]The trees are found inMyanmar,Thailand,Laos,Cambodia,andVietnam.Common names in S.E. Asia are: Cambodian: "Neang Nuon", Thai: "Mai Ching Chan" (ไม้ชิงชัน), Laos: "Mai Kham Phii" (ໄມ້ຄຳພີ), Myanmar: "tamalan" (တမလန်း).
In Vietnamesecẩm laiortrắc laiis a generic name for "rosewood" trees. Based at theSaigon Botanic Gardens,the French botanistJBL Pierredescribed a number of local variations in tree dimensions and characteristics of seed pods (which are usuallyglabrous).[6]Species he named are now considered to be synonyms:
- Dalbergia bariensis: cẩm lai bông, cẩm laiBà Rịa– 15-20 m trees – pods 25 x 120mm, usually 1 seeded
- Dalbergia dongnaiensis: cẩm laiÐồng Nai– 10-15 m trees – pods 30-45 x 100-110mm, 1 seed
- Dalbergia duperreana: trắc(Cambodia) – 10-20 m trees – pods 27-40 x 120mm
- Dalbergia mammosa: cẩm lai vú- 20 m trees – pods 22 x 100mm, not narrowing on 1-2 seeds
- Dalbergia olivieri: cẩm lai bông- 25 m trees – pods 17 x 60-80mm, 1 or 2 (rarely 3) seeds
Uses
[edit]The wood of this rosewood-family tree is valuable for ornamental work includingWoodturningand furniture. The sapwood is yellowish-white with dark brown heartwood. The heartwood is very hard and heavy. The lumber is sold under the namesBurmese rosewood,Laos rosewood,andAsian rosewood.
In contrast to the co-occurringDalbergia cochinchinensis,Dalbergiaoliveriavoids drought by chlorophyll content and compromise productivity. Its isohydric behaviour suggests it is suitable to be grown in deciduous forests.[7]
