“…Wind and/or water dispersal seem likely for these species. Phylogenetic analyses do not suggest a close relationship between D. cochinchinensis and D. oliveri (Hartvig et al., ; Vatanparast et al., ), and there is no knowledge of hybridization between them.…”

Indochina is a biodiversity hot spot and harbors a high number of endemic species, most of which are poorly studied. This study explores the genetic structure and reproductive system of the threatened endemic timber species Dalbergia cochinchinensis and Dalbergia oliveri using microsatellite data from populations across Indochina and relates it to landscape characteristics and life‐history traits. We found that the major water bodies in the region, Mekong and Tonle Sap, represented barriers to gene flow and that higher levels of genetic diversity were found in populations in the center of the distribution area, particularly in Cambodia. We suggest that this pattern is ancient, reflecting the demographic history of the species and possible location of refugia during earlier time periods with limited forest cover, which was supported by signs of old genetic bottlenecks. The D. oliveri populations had generally high levels of genetic diversity (mean H e = 0.73), but also strong genetic differentiation among populations (global GST = 0.13), while D. cochinchinensis had a moderate level of genetic diversity (mean H e = 0.55), and an even stronger level of differentiation (global GST = 0.25). These differences in genetic structure can be accounted for by a higher level of gene flow in D. oliveri due to a higher dispersal capacity, but also by the broader distribution area for D. oliveri, and the pioneer characteristics of D. cochinchinensis. This study represents the first detailed analysis of landscape genetics for tree species in Indochina, and the found patterns might be common for other species with similar ecology.

A systematic treatment of the genus Dalbergia for the Flora Malesiana (FM) region is presented. The treatment includes a genus description, two keys to the species, an enumeration of the species present in the FM-area with names and synonyms, details of distribution, habitat and ecology and where needed some notes, three new species (D. minutiflora, D. pilosa, D. ramosii For the Flora Malesiana treatment we recognise 33 species. In the following sections a genus description, two keys to the Malesian species, notes on species and typification, one new name and the description of three new species will be given. DalbergiaDalbergia L.f. (1781) Trees, erect or scandent shrubs to woody climbers, sometimes spiny, with or without red sap. Leaves imparipinnate, rarely unifoliolate; stipules present, caducous, very rarely persistent; stipellae absent; leaflets usually alternate. Inflorescences axillary, terminal or raminascent, racemes or panicles. Bracts subpersistent or caducous. Bracteoles present, caducous or (sub)-persistent. Calyx bell-shaped, bilabiate, upper lip 2-toothed, lower lip 3-toothed, median (lowest) tooth usually longest. Corolla: standard without callosities; wings usually sculpted, adhering to the keel petals; keel petals slightly shorter than or as long as the wings. Stamens 9 -10, monadelphous, than usually an open sheath, or diadelphous than usually 2 bundles of 5 (or 1 of 5 and 1 of 4); anthers all equal, fertile. Ovary stipitate; ovules few; stigma terminal. Fruits indehiscent, (strongly) flattened, often thickened around the seeds or less flattened, ± leathery or woody, sometimes articulate. Seeds flattened bean-shaped to flattened ellipsoid, hilum usually eccentric.Distribution -C. 185 species, pantropic, in Malesia 33 species.Note -Corolla parts are usually glabrous. Only in very few specimens hairs at the standard were observed: PPI 1294 (Stone et al.): some hairs at the outside of the standard, this specimen is included in D. canescens, S. 23493 (Anderson): some hairs at the standard. This specimen has also diadelphous stamens (9 + 1). It may represent a new species. For several species the annotations of the habit are at first confusing. Label information gives for the same species: (scandent) shrub, tree or climber. Probably plants of the species start live as shrub or small tree with long supple and ± climbing branches. Later on or when good support is present they may develop into large lianas. Problems with identification are, in part, due to uncertainties of the true habit when fully mature. In many species not all ovules develop into seeds. KEY TO THE SPECIES Of

“…However, the combined barcoding ITS + psbA-trnH yields the highest rates of barcode gap due to the presence of a high rate of parsimony informative sites. Vatanparast et al (2013) performed a phylogeny analysis based on ITS barcoding and included 64 Dalbergia species and Hartvig et al (2015) tested 31 Dalbergia species based on ITS, matK and rbcL barcoding. Our dataset included almost all the detected Dalbergia species sequences aimed at barcoding (ITS, matK, rbcL and psbA-trnH) accessed from GenBank (Supplementary Table S1).…”

“…Dalbergia (Fabaceae: Papilionaceae) is a genus of trees, shrubs, or woody climbers of around 250 species that has a wide distribution in tropical and subtropical regions in South America, Africa, Asia and Madagascar (Cardoso et al 2013;Saha et al 2013;Vatanparast et al 2013). The extractives of many Dalbergia species are known for their analgesic, anti-inflammatory and antipyretic activities and used in case of cough, toothache, skin lesions and stomach ache, etc.…”

“…Yu et al (2016) demonstrated that the trnH-psbA region is suitable for identification of D. odorifera and D. tonkinensis, which are close to each other. Combined analyses of Dalbergia at species level, based on molecular methods, are still incomplete (Lavin et al 2001;Cardoso et al 2013;Vatanparast et al 2013). Therefore, a more comprehensive phylogenetic study of the genus Dalbergia is needed.…”

Abstract:The genus Dalbergia contains approximately 250 species with many valuable trees being destroyed by targeted and illegal logging. DNA barcoding is a reliable method for the molecular identification of different species and resources conservation. In the present study, the specimen discrimination ability of internal transcribed spacer (ITS), matK, rbcL and psbA-trnH barcoding were tested on Dalbergia sequences, downloaded from the National Center for Biotechnology Information (NCBI), and the combined barcoding ITS + matK + rbcL was used to identify unknown specimens. It was found that ITS + matK + rbcL have good discrimination rates based on the analysis methods best match (BM) and best close match (BCM). These barcodes also have the best performance concerning barcode gap distribution, and are able to discriminate unknown specimens from South-China. Furthermore, it was demonstrated that D. tamarindifolia and D. rubiginosa are also relatively close to sister-species D. pinnata and D. candenatensis within the phylogenetic Dalbergia tree. Considering the overall performance of these barcodes, we suggest that the ITS + matK + rbcL region is a suitable barcode for identifying Dalbergia species.
