03B187B0FFC6B66C2BD6FE6FA2EABA19.taxon	distribution	Distribution and ecology: — As the type species of the genus Dalbergia, D. lanceolaria has a wide distribution, ranging from the Indian Subcontinent to the Indochina Peninsula (Li 2017). This study represents the first record of D. lanceolaria in China, currently known only from southern Yunnan Province. The species is typically found in or near limestone mountainous regions.	en	Dong, Jin-Long, Jiang, Kai-Wen, Biao, A., Shu, Nan, Huang, Hui-Wen, Song, Zhu-Qiu, Pan, Bo, Tu, Tie-Yao, Li, Shi-Jin (2025): Three new recorded species of the genus Dalbergia (Fabaceae: Papilionoideae: Dalbergieae) from southwestern China.

The first part “ fi ‼ v / fiŀ (ă) v ” is derived from the specific epithet lanceolaria, referring to the usually lanceolate pods of Dalbergia lanceolaria, while “ n ḛ / ñ ḛ ” is the common Chinese name for the genus Dalbergia. The Chinese name of D. lanceolaria was originally given as “ fi ‼ 叶n ḛ / fiŀ (ă) ĸñ ḛ ” by Li (2017), where the first part “ fi ‼ 叶 / fiŀ (ă) ĸ ” means “ lanceolate leaf / leaflet ”. This name is inappropriate since the species usually does not have lanceolate leaflets.	en	Dong, Jin-Long, Jiang, Kai-Wen, Biao, A., Shu, Nan, Huang, Hui-Wen, Song, Zhu-Qiu, Pan, Bo, Tu, Tie-Yao, Li, Shi-Jin (2025): Three new recorded species of the genus Dalbergia (Fabaceae: Papilionoideae: Dalbergieae) from southwestern China.

03B187B0FFC6B66C2BD6FE6FA2EABA19.taxon	conservation	Conservation status: — Following the IUCN Red List Standards and Petitions Subcommittee (2024), Dalbergia lanceolaria is assessed as Least Concern (LC) due to its wide distribution and relatively common occurrence in Xishuangbanna Prefecture.	en	Dong, Jin-Long, Jiang, Kai-Wen, Biao, A., Shu, Nan, Huang, Hui-Wen, Song, Zhu-Qiu, Pan, Bo, Tu, Tie-Yao, Li, Shi-Jin (2025): Three new recorded species of the genus Dalbergia (Fabaceae: Papilionoideae: Dalbergieae) from southwestern China.

03B187B0FFC6B66C2BD6FE6FA2EABA19.taxon	discussion	Taxonomic remarks: — Among Chinese species of Dalbergia, D. lanceolaria is most closely related to D. assamica Bentham (in Miquel 1852: 256), with very subtle morphological differences between them. These subtle distinctions led Thothathri (1983 [1985], 1987) to reduce the latter to a variety of D. lanceolaria subsp. lanceolaria, as var. assamica (Benth.) Thothathri (1983: 171). According to Niyomdham (2002), D. lanceolaria can be distinguished from D. assamica by its coarse and prominent secondary veins and reticulation on both surfaces of mature leaflets when dry (vs. thin and fine secondary veins and reticulation, rather obscure on abaxial surface when dry in D. assamica). It can be also distinguished from D. assamica by its flanking bark (vs. longitudinally fissured, cf. Dholariya et al. 2019) Additionally, our observations reveal that mature seeds of D. lanceolaria separate from the inner surface of the pod's seed chamber, causing them to rattle when the ripe pods are shaken. In contrast, mature seeds of D. assamica remain firmly attached to the inner wall of the pod's seed chamber and do not rattle when shaken.	en	Dong, Jin-Long, Jiang, Kai-Wen, Biao, A., Shu, Nan, Huang, Hui-Wen, Song, Zhu-Qiu, Pan, Bo, Tu, Tie-Yao, Li, Shi-Jin (2025): Three new recorded species of the genus Dalbergia (Fabaceae: Papilionoideae: Dalbergieae) from southwestern China.

03B187B0FFC5B66A2BD6FAC3A3B2B9E1.taxon	conservation	Conservation status: — Since we examined only one collection of Dalbergia nigrescens from China made by one of us (see Specimens examined below), we follow Barstow (2001) in assessing the species as Data Deficient (DD).	en	Dong, Jin-Long, Jiang, Kai-Wen, Biao, A., Shu, Nan, Huang, Hui-Wen, Song, Zhu-Qiu, Pan, Bo, Tu, Tie-Yao, Li, Shi-Jin (2025): Three new recorded species of the genus Dalbergia (Fabaceae: Papilionoideae: Dalbergieae) from southwestern China.

03B187B0FFC5B66A2BD6FAC3A3B2B9E1.taxon	discussion	Taxonomic remarks: — (1) The description of inflorescence and flowers, as well as the phenology given below, are based mainly on Li (2017), as we examined only one fruiting collection. (2) While previous literature (Li 2017) documented that Dalbergia nigrescens could be characterized by leaflets that turn dark brown to black when dried, our recent observations suggest that this darkening is largely attributable to specimen processing conditions. When dried rapidly using a drying oven (approximately 60 ° C), specimens may retain their green coloration. Although this character may be useful to some degree, caution should be exercised when relying on it as a distinguishing feature. Based on further observations, D. nigrescens can be distinguished from related species by several pod characteristics. It differs from D. assamica by having pod valves that are obviously thickened and raised around seeds (vs. not or slightly thickened and raised around seeds). It can be separated from D. lanceolaria by the inconspicuously reticulated thickened portions of the valves (vs. obviously reticulated). Finally, it differs from D. oliveri by its generally shorter pods [(4 –) 4.5 – 8.5 vs. 9 – 11 (– 14) cm] combined with inconspicuously reticulated thickened valve portions (vs. reticulation absent). Nevertheless, the relationships among these four species require further investigation.	en	Dong, Jin-Long, Jiang, Kai-Wen, Biao, A., Shu, Nan, Huang, Hui-Wen, Song, Zhu-Qiu, Pan, Bo, Tu, Tie-Yao, Li, Shi-Jin (2025): Three new recorded species of the genus Dalbergia (Fabaceae: Papilionoideae: Dalbergieae) from southwestern China.

03B187B0FFC3B6682BD6FD5CA044BA3D.taxon	conservation	Conservation status: — Although Dalbergia oliveri is widely distributed in the Indochina Peninsula, it has been heavily exploited for its valuable hardwood, which is close-grained, red-colored, and prized for furniture and ornamental work (Thothathri 1987). Its commercial value in the timber trade (Phong et al. 2011) has led to widespread deforestation and population decline. Despite reports that this species may be locally common in Yingjiang County (Bin Tian, pers. comm.), we follow Barstow et al. (2022) in assessing it as Critically Endangered (CR A 2 cd + 3 cd + 4 cd).	en	Dong, Jin-Long, Jiang, Kai-Wen, Biao, A., Shu, Nan, Huang, Hui-Wen, Song, Zhu-Qiu, Pan, Bo, Tu, Tie-Yao, Li, Shi-Jin (2025): Three new recorded species of the genus Dalbergia (Fabaceae: Papilionoideae: Dalbergieae) from southwestern China.

03B187B0FFC3B6682BD6FD5CA044BA3D.taxon	discussion	Taxonomic remarks: — (1) The description of inflorescence and flowers, as well as the phenology given below, are based mainly on Li (2017), as we examined only one fruiting collection. (2) Among Chinese species of Dalbergia, D. oliveri is most closely related to D. lanceolaria L. f. and its allies, but can be readily distinguished from them by its pods being obviously thickened and raised around seeds without reticulation [vs. pods less prominently thickened and raised around seeds with inconspicuous to obvious reticulation, cf. Taxonomic remark (2) under D. nigrescens].	en	Dong, Jin-Long, Jiang, Kai-Wen, Biao, A., Shu, Nan, Huang, Hui-Wen, Song, Zhu-Qiu, Pan, Bo, Tu, Tie-Yao, Li, Shi-Jin (2025): Three new recorded species of the genus Dalbergia (Fabaceae: Papilionoideae: Dalbergieae) from southwestern China.

03B187B0FFC1B6682BD6FE18A0A9BCD6.taxon	description	The type species of the genus Dalbergia, D. lanceolaria L. f., and its allies comprise section Dalbergia. This section was previously known as section Dalbergaria Prain (1905 [1904]: 85). However, according to Art. 22.2 of the International Code of Nomenclature for algae, fungi, and plants (ICN; Madrid Code, Turland et al. 2025), a name of a subdivision of a genus that includes the type of the adopted, legitimate name of the genus is not validly published unless its epithet repeats the generic name unaltered. Therefore, the sectional name Dalbergaria was not validly published and should not be used; instead, the autonym sect. Dalbergia should be adopted. This section, based on the treatments by Prain (1905 [1904]) and Thothathri (1987), as well as the species key by Li (2017), comprises ca. 16 species distributed in tropical and subtropical Asia, and has been supported as a monophyletic clade in phylogenetic studies 1,2 (Vatanparast et al. 2013, Sotuyo et al. 2022). Members of this section are characterized by their stamens in 5 + 5 diadelphous arrangement [except D. polyadelpha Prain (1905 [1904]: 84), stamens irregularly separated to incompletely 3 – 5 - adelphous on upper part] and coriaceous pods. Currently, nine species of this section are known from China. A key to these species (mainly based on fruiting specimens) is provided below.	en	Dong, Jin-Long, Jiang, Kai-Wen, Biao, A., Shu, Nan, Huang, Hui-Wen, Song, Zhu-Qiu, Pan, Bo, Tu, Tie-Yao, Li, Shi-Jin (2025): Three new recorded species of the genus Dalbergia (Fabaceae: Papilionoideae: Dalbergieae) from southwestern China.

03B187B0FFC1B6682BD6FE18A0A9BCD6.taxon	discussion	Notes: — 1 Phylogenetic analyses by Vatanparast et al. (2013) and Sotuyo et al. (2022) did not place Dalbergia sericea within the Dalbergia sect. Dalbergia clade. Upon examining the voucher specimen (BANGLADESH. Chittagong, 25 April 1994, A. M. Huq & M. K. Mia 10336 [L]) used in their studies, we found it to be a misidentification. This specimen likely represents a species closely related to Dalbergia velutina Bentham (in Miquel 1852: 255), characterized by membranous pods containing elongate seeds. 2 Notably, phylogenetic analyses based on chloroplast genomes by Rather et al. (2025) placed D. obtusifolia Prain (1901 [1902]: 42) and D. mimosoides Franchet (1889: 187) within the Dalbergia sect. Dalbergia clade. However, this result may be based on misidentification of voucher specimens (vouchers not traced by the current authors) and conflicts with both morphological data (see Li 2017) and our unpublished molecular phylogenetic data. Therefore, their results are not recognized here. 3 Li (2017), in his key to species and species descriptions, stated the leaflet number of Dalbergia hupeana as 3 – 5. This should be corrected to 3 – 5 - paired leaflets.	en	Dong, Jin-Long, Jiang, Kai-Wen, Biao, A., Shu, Nan, Huang, Hui-Wen, Song, Zhu-Qiu, Pan, Bo, Tu, Tie-Yao, Li, Shi-Jin (2025): Three new recorded species of the genus Dalbergia (Fabaceae: Papilionoideae: Dalbergieae) from southwestern China.
