03B187C23234FFAB249519F0FACDF9CD.taxon	diagnosis	Diagnosis. The new genus Huchimingia is most closely related to Antheroporum and Ohashia within the non-canavanine group of the core Millettieae (Fig. 1). Huchimingia is distinguished from Antheroporum by having conspicuous buds covered with scales (vs. inconspicuous), single inflorescence in the leaf axil (vs. 3 ‒ 5 inflorescences), large (vs. small) flowers, distinct (vs. indistinct) hypanthium, ebracteolate calyx (vs. two bracteoles at the base of calyx), triangular (vs. subtruncate) calyx lobes, oblong (vs. elongated) wing petals, and flat (vs. inflated and vacuous) pods. Huchimingia is morphologically distinguished from Ohashia by its tree (vs. liana) habit, conspicuous buds covered with scales (vs. inconspicuous), very indistinct (vs. distinct and thick) brachyblasts, 2 (vs. 7 ‒ 10) flowers per brachyblast, ebracteolate flowers (vs. two bracteoles at the base of calyx), large (vs. small) flowers, distinct (vs. indistinct) hypanthium, oblong (vs. elongated) wing petals, stipitate (vs. estipitate) ovary, and stipitate and dehiscent (vs. estipitate and indehiscent) pods. Additionally, Huchimingia is also related to Hesperothamnus (Fig. 1), but it differs in having conspicuous buds covered with scales (vs. inconspicuous), leaves without (vs. with) stipels, very indistinct (vs. distinct) brachyblasts, 2 (vs. 3 ‒ 5) flowers per brachyblast, distinct (vs. indistinct) hypanthium, stipitate (vs. estipitate) ovary and pod, and Asian (vs. American) distribution.	en	Song, Zhu-Qiu, Li, Shi-Jin, Mattapha, Sawai (2022): Huchimingia, a new genus segregated from Millettia (Leguminosae, Millettieae) based on morphological and molecular evidence.

03B187C23237FFA924951898FA2CFB5A.taxon	distribution	Distribution and ecology. This species is known from China (Guangxi and Yunnan), Thailand (Lampang), and Vietnam (Bac Kan, Cao Bang, Ha noi, Hoa Binh, Lao Cai, Nghe An, Ninh Binh, Thai Nguyen, Thanh Hoa, and Tuyen Quang), at an altitude of 100 – 600 m. The species appears to be flowering before or as leaves expand. It flowers from February to April, and fruits from May to the next April. It may be considered as ‘ Least Concern’ (LC) according to IUCN criteria (IUCN 2012).	en	Song, Zhu-Qiu, Li, Shi-Jin, Mattapha, Sawai (2022): Huchimingia, a new genus segregated from Millettia (Leguminosae, Millettieae) based on morphological and molecular evidence.

03B187C23237FFA924951898FA2CFB5A.taxon	discussion	Notes. Wei and Pedley (2010) recorded this species with branched pseudoracemes; however, based on herbarium specimens and living individuals, we observed this species as having unbranched pseudoracemes, which have quite indistinct brachyblasts with two flowers at each brachyblast. This species is easily recognized by 5 – 9 - foliolate leaves, asymmetric lateral leaflets, leafless pseudoracemes, 1.0 – 1.8 cm long flowering pedicels, 2 - ovuled ovary, and falcateoblanceolate and woody pods with 1 – 2 seeds. Here, we describe the seedlings of this species for the first time, which show that it has epigeal and phanerocotylar cotylendons (Fig. 4). This seedling type is consistent with previous observations in the tribe Millettieae (De Vogel 1980, Sousa and de Sousa 1981, Khan et al. 2015). However, the eophyll (first leaves) of Huchimingia ichthyochtona appears to bear more leaflets (7 – 9 leaflets), while eophylls with one or three leaflets are usually found throughout the tribe, including in Hesperothamnus, Piscidia, Tephrosia, and most species of Lonchocarpus (Sousa and de Sousa 1981). In the genus Millettia, Khan et al. (2015) found that M. pinnata had 1 - foliolate eophyll. Our observations showed M. leptobotrya Dunn (1912: 189), M. xylocarpa Miquel (1855: 157) and M. versicolor Baker (1871: 129) also have 1 - foliolate eophylls, while M. macrostachya Collett & Hemsl. has a 3 - foliolate eophyll.	en	Song, Zhu-Qiu, Li, Shi-Jin, Mattapha, Sawai (2022): Huchimingia, a new genus segregated from Millettia (Leguminosae, Millettieae) based on morphological and molecular evidence.

It flowers after leaves expand, from July to November, and fruits from December to the next October. It was evaluated as ‘ Near Threatened’ (NT) by Rai and Lalramnghinglova (2011).	en	Song, Zhu-Qiu, Li, Shi-Jin, Mattapha, Sawai (2022): Huchimingia, a new genus segregated from Millettia (Leguminosae, Millettieae) based on morphological and molecular evidence.

03B187C23236FFAE24951D2BFEA5FA03.taxon	discussion	Notes. It seemed controversial when Galedupa piscidia Roxb. was combined under Millettia. Although M. piscidia (Roxb.) Wight was accepted by most authors (Walpers 1842, Bentham 1852, Baker 1876, Brandis 1906, Dunn 1912, Kanjila et al. 1938, Haridasan and Rao 1985, Sanjappa 1992, Lock and Heald 1994, Kumar and Sane 2003), the earlier name, M. piscidia (Roxb.) Wight & Arn., was accepted by some authors (e. g., Lôc 1996 a, Kress et al. 2003) and was included in two databases, i. e., International Plant Name Index (www. ipni. org) and Tropicos (www. tropicos. org). When publishing Millettia, Wight and Arnott (1834) pointed out that Galedupa piscidia Roxb. was probably included in the genus, but the epithet was not definitely associated with the generic name Millettia. Thus, the combination M. piscidia should not be attributed to Wight and Arnott according to Article 35.2 of ICN (Turland et al. 2018). Instead, M. piscidia should be attributed to Wight, who validly published it in 1838 (Wight 1838). Lock and Heald (1994) noted that this species was also distributed in Thailand and provided a single collection (R. Geesink et al. 7942). This collection was previously cited as the voucher of this species by Evans et al. (1985) in a chemical study of Millettieae (then Tephrosieae). However, the examination of the voucher specimens (L 3978527 and L 3978629) showed that they had pods without distinct stipes, leaves with stipels, and about 17 asymmetric leaflets per leaf — quite different to those of Huchimingia piscidia. The two specimens were identified as “ Millettia spec. ” by Frits Adema in 2018, and probably represent Millettia brandisiana Kurz based on our observations. Thus, the record of this species in Thailand should be excluded. In addition, this species was previously recorded from Sikkim by some authors (e. g., Baker 1876), but Grierson and Long (1987) noted that the record from Sikkim was based on misidentified specimens of Derris microptera Benth., and we have not found specimens of this species from Sikkim.	en	Song, Zhu-Qiu, Li, Shi-Jin, Mattapha, Sawai (2022): Huchimingia, a new genus segregated from Millettia (Leguminosae, Millettieae) based on morphological and molecular evidence.

03B187C23231FFAF24951DD1FE71FBC7.taxon	discussion	Notes. The flowering collection A. F. G. Kerr 4840 was erroneously identified as this species by Lôc (1996 a), in which its distribution was extended to Thailand and was further confirmed by Lôc and Vidal (2001). However, this gathering has asymmetric leaflets, which is an important feature of Huchimingia ichthyochtona and was correctly cited by Craib (1928). Recently, Mattapha (2020) also recorded this species (as Millettia podocarpa) in the Flora of Thailand, but described it with asymmetric leaflets and a 2 - ovuled ovary, which are consistent with those of H. ichthyochtona. Up to now, we did not found any specimens of H. podocarpa from Thailand. Huchimingia podocarpa is recognized by the combination of multiple characters, including 3 – 9 (usually 7 – 9) symmetric leaflets, leafy pseudopanicles, long teeth of calyx (more than 3 mm), 4 - ovuled ovary, and long and woody pods (14 – 27 cm).	en	Song, Zhu-Qiu, Li, Shi-Jin, Mattapha, Sawai (2022): Huchimingia, a new genus segregated from Millettia (Leguminosae, Millettieae) based on morphological and molecular evidence.

03B187C23233FFAC24951898FE31FC20.taxon	discussion	Notes. Due to its standard petal with inflexed auricles and pods with four wings, this species was previously placed in Millettia sect. Fragiliflorae Dunn by Song et al. (2019), who also pointed out its similarity with Millettia sect. Podocarpae Dunn. But it should be included in the genus Huchimingia by having large, subglobose, scaly buds (Fig. 3 E), pseudoracemes with very indistinct brachyblasts, two flowers on each brachyblast, conspicuous large bracts (mistakenly described as bracteoles by Song et al. (2019 )), ebracteolate calyx, hollow receptacle, and stipitate ovary and pod (Fig. 3 F). The systematic position of this species within Huchimingia was also well supported by molecular evidence (Fig. 1).	en	Song, Zhu-Qiu, Li, Shi-Jin, Mattapha, Sawai (2022): Huchimingia, a new genus segregated from Millettia (Leguminosae, Millettieae) based on morphological and molecular evidence.
