Abstract

Korean species within the genus Astragalus have been taxonomically revised based on herbarium specimens and field examinations. In this study, we recognized the following eight species and one variety: A. laxmannii subsp. laxmannii, A. dahuricus, A. sikokianus, A. uliginosus, A. schelichowii, A. setsureianus, A. mongholicus var. dahuricus, A. mongholicus var. nakaianus, and A. sinicus. Based on recent taxonomic progress with this genus, their scientific names are being reconsidered. A Korean plant, previously recorded as A. adsurgens, is included in the polymorphic taxa A. laxmannii subsp. laxmannii. Astragalus koraiensis was initially described from Gangwon Province as an endemic species, and it is now regarded as conspecific with A. sikokianus. Furthermore, the taxonomic entities and their morphological characteristics have been clarified for A. schelichowii and A. setsureianus, both of which are not well known in Korea. We provide a key to these species and enumerate their synonymies and taxonomic notes.

Astragalus L. (Fabaceae; Papilionoideae; Galegeae) is one of the largest genera of flowering plants, comprising at least 2,300 species that are distributed mainly in northern temperate regions (Polhill, 1981; Lock and Schrire, 2005). Its large size and the lack of solid intra-generic classifications continue to cause taxonomic confusion at the global and regional levels. Recently, Podlech and Zarre (2013) revised Astragalus with keys, full descriptions, and sectional assignments for almost all of the Old World species. Although this generic framework functions on a global scale, the taxonomic entity of some regionally endemic species as well as their distributional ranges remain unclear. Likewise, the current taxonomic understanding of Korean Astragalus species is still far from adequate. Thus, supplementing the Korean Astragalus taxonomy is necessary if researchers are to stay apace with recent taxonomic progress in that genus.
The scientific names and numbers of Astragalus species described in Korean floras have long been confused (Chung, 1957; Lee, 1980; Lee W., 1996; Lee Y., 1996; Im, 1998; Lee, 2003; Lee, 2006; Choi, 2007). The species diversity of Korean Astragalus is mostly concentrated in the high mountains of the northern regions, thereby hindering attempts to elucidate its taxonomic entity. Furthermore, the illegitimate or invalid scientific name of some Korean endemic species has made their taxonomy more problematic. Accordingly, anatomical, cytological, and medicinal studies of Korean Astragalus species have relied upon those incorrect scientific names, leading to a lack of consensus between those taxonomic characters and each of the taxa. Although some research has recently been conducted in this regard with Korean Astragalus species (Choi et al., 2013; Han et al., 2013; Song and Heo, 2014), those examinations have primarily focused upon the medicinally important A. mongholicus Bunge and/or have not taken a comprehensive approach. Consequently, the taxonomic entity of most Korean Astragalus species is not well understood.
To improve the scientific knowledge about those species, one must test the newly available taxonomic treatments for Old World Astragalus while also clarifying the morphology, scientific name, and distribution of Korean Astragalus species. Thus, we present here our investigation of Korean species and our review of other studies from a taxonomic perspective.

Materials and Methods

Field samples of Korean Astragalus species were collected from 2002 to 2015 and kept in the herbarium of Inha University (IUI). In addition, morphological examinations were conducted with dry specimens from the following herbaria: Chonnam National University (CNU); Ewha Womans University (EWH); National Institute of Biological Resources, Korea (KB), Kyungpook National University (KNU); Kangwon National University (KWNU); Korea National Arboretum (KH); Sungkyunkwan University (SKK); Seoul National University, College of National Sciences (SNU); Seoul National University, College of Agriculture Life Sciences (SNUA); the Warm-Temperate Forest Research Center, Korea (WTFRC); Tohoku University (TUS); Tokyo University (TI); The New York Botanical Garden (NY); and the Chinese Academy of Sciences, Beijing (PE). We also studied photographic slides of specimens (Lee, 2012) from the herbaria of Kyoto University (KYO) and the National Museum of Nature and Science, Japan (TNS).
All morphological examinations of these herbarium specimens were done with a dissecting microscope. Habitats, growth habits and other features of each species were observed and their photographs were taken in the field. Descriptions for each taxon were based on mature and well-developed plants. In this paper, the terminology concerning plant morphology follows that of Harris and Harris (1994), the Korea National Arboretum (2010), and Beentje (2012). The accepted names were provided according to the International Code of Nomenclature for algae, fungi, and plants (McNeill et al., 2012).

  • Korea: Yanggang-do (Mt. Baekdu), Seoul (introduced), and Jeju-do. Bushes and meadows in forests.

Note: The scientific name of Astragalus adsurgens Pall. has long been applied to East Asian plants, including specimens found in Korea (Lee, 1980; Lee W., 1996; Lee Y., 1996, Im, 1998; Lee, 2003; Lee, 2006; Choi, 2007). However, recent taxonomic treatments have merged this taxon with A. laxmannii Jacq. (Podlech, 1993). This treatment is now broadly accepted for plants from both the Old World (Xu and Podlech, 2010; Podlech and Zarre, 2013) and the New World, i.e., North America (Barneby and Welsh, 1996). Furthermore, A. laxmannii (= A. adsurgens) is now divided into three subspecies (Podlech and Zarre, 2013). The A. laxmannii subsp. laxmannii is restricted to Old World; the others, to New World. Based on such a species boundary, specimens from North Korea are similar in their gross morphology to other East Asian A. laxmannii subsp. laxmannii. This plant has also been introduced into Nanji Park in Seoul as a resource for restoration.
However, plants on Jeju Island differ from those on the Asian continent because of several external morphologies, such as leaf size (3–7 cm for Jeju Isl. vs. 5–15 cm for the Continent); leaflet number [9–15 vs. 11–27]; lengths of the inflorescence (2–4cm vs. 3–20 cm), corolla (10–12 mm vs. 12–16 mm), and calyx (3–4 mm vs. 5–6 mm); and flowering period (Aug.–Sept. vs. Jun.–Jul.). In addition, the plants from Jeju Isl. were once separated from A. adsurgens and known as var. alpinus (Nakai, 1914) without description (nom. nud.). According to the taxonomic note for A. caeruleus Bunge from Podlech and Zarre (2013), the population on Jeju Isl. also might be conspecific to that species. However, wide-ranging natural populations of the species have demonstrated high plasticity of morphological characters and flowering season in East Asia (Podlech and Zarre, 2013). Variations within this species have also been observed for cytological features (Hongo et al., 1996) and in how plants are cultivated as forage crops (Fu et al., 1982). Although the Jeju population shows a distinct morphology, differences in characteristics have also been described for specimens from China, Japan, and Russia. Moreover, our preliminary DNA analysis reported previously (Kim, 2004) indicated that these plants have close affinity with A. laxmannii subsp. laxmannii. Because it is difficult to separate this variant based merely on external macro-morphology, an adequate treatment will require more abundant and detailed data including information about DNA sequences, karyotypes, and micromorphology across its entire range of distribution. For now, we have made provisional decisions about those Jeju Isl. plants as this polymorphic species. The description and figure (Fig. 1) presented in this paper is exclusively based on Jeju Isl. plants.

  • Distribution: China, Russia (Far East, Siberia), Mongolia, and Korea.

  • Korea: Yanggang-do (Mt. Baekdu), Hamgyeongbuk-do, Jagang-do, Seoul-si and Gangwon-do (introduced). Meadows and road sides on mountains of North Korea and anthropogenically disturbed areas in South Korea.

Note: This species naturally grows on mountains in the northern part of Korea. Plants have also recently been found in Nanji Park in Seoul-si and Hwacheon-dam in Gangwon-do, possibly introduced from China as part of a seed mix used as a protective ground cover for erosion control in that newly constructed area. Most floras record the distribution of this species within Gyeongsangbuk-do of Korea (Chung, 1957; Lee, 1980; Lee W., 1996; Lee Y., 1996; Im, 1998; Lee, 2003; Lee, 2006; Choi, 2007). However, we have found no specimens in South Korea except for recently naturalized populations. This species is easily distinguished from others by its purplish flowers and curved pods.

  • Distribution: Korea and Japan.

  • Korea: Incheon-si, Gangwon-do, Gyeongsangbuk-do, Jeollanam-do. Growing on seashores, roadsides, river banks, seashore embankments, streams of South Korea.

Note: Astragalus koraiensis Y.N. Lee has been confused with its congener A. sikokianus. The collection date, location, and the site of the herbarium deposit (EWH) for type specimen of A. koraiensis were initially recorded by Lee (1981) but can no longer be traced. Moreover, our attempts to find a type specimen of A. koraiensis in domestic herbaria (including EWH) and/or the exact specimen identified as A. koraiensis by Lee have been unsuccessful.
Despite the lack of a type specimen, the description and photographs of A. koraiensis published by Lee (1981) are unquestionably a match for A. sikokianus, and none of the specimens collected from Korea can be morphologically distinguished from A. sikokianus. A separate, proper taxonomic treatment will be presented in the future, using morphological and molecular evidence for A. sikokianus and related congeners (Choi et al., unpublished).

  • Korean name: 긴꽃대황기 Gin-kkot-dae-hwang-gi

    Perennial herb, pubescent with medifixed hairs; stems 20–40 cm long, finely covered with white hairs. Leaves 9–15 cm long, petiole 1–2 cm long; stipules connate to the middle, thinly scarious triangular, acuminate, 5–11 mm long, sparsely hairy; leaflets subsessile, elliptic to oblong-ovate, round-tipped, often emarginated, 9–12 pairs 10–25 mm long, pubescent. Inflorescence elongate racemes, 2–3cm long (3–11 cm in fruit), densely 10 to 20-flowered; flowers spreading on inflorescence; peduncles erect, 4–11 cm long (9–15 cm in fruit), covered with hair; bracts lanceolate to ovate-lanceolate, acuminate, as long as or slightly longer than calyx, ca. 2 mm wide, finely covered with mixed hairs; pedicels ca. 1 mm long.

    Distribution: Russia (Far East, Siberia), China (Jilin Prov.), Korea, Japan.
    Korea: Yanggang-do (Mt. Baekdu), Hamgyeongbuk-do, Hamgyeongnam-do. Growing on high mountains of North Korea.
Note: This species is similar to A. uliginosus and has been classified within the same section, Uliginosi A. Gray (Podlech and Zarre, 2013). A Korean distribution was first recorded by Murata (1984) and has since then been confirmed by Lee W. (1996), based on KYO specimens collected from Hamkyungbuk-do. This species is distinguished by its hairy ovaries and pods when compared with glabrous organs from A. uliginosus (Komarov, 1904; Shishkin, 1946; Murata, 1984) as well as by its calyxes, which are shorter than those from the latter species (Podlech and Zarre, 2013). We examined specimens for these two species from PE, KYO, TNS, and domestic herbaria and found that, in addition to those ovary and pod characters mentioned above, A. schelichowii differs from A. uliginosus because a leaflet from the former has an emarginate apex and the calyx is 5–6 mm long while the latter has a mucronulate apex and an 8–9 mm-long calyx. Our investigation of various herbarium samples revealed that many specimens of A. schelichowii have been misidentified as A. uliginosus or A. laxmannii (=A. adsurgens). Although plants of A. schelichowii have not been recorded from China, our field survey verified several such plants in Chinese territory at Mt. Baekdu (Jilin Prov.), along the Korean border (Fig. 2). Therefore, its distribution in China requires further investigation.

  • Korean name: 설령황기 Seol-ryeong-hwang-gi

Perennial herb, pubescent with basifixed hairs; stems 15–30 cm long, several stems tufted and ascending or erect, sparsely covered with hairs. Leaves 3–6 cm long, petiole short; stipules free, cauline, green, foliaceous, triangular-ovate, subacute, 4–6 mm long, sparsely hairy especially at the margins; leaflets subsessile, elliptic, usually emarginated, 5–6 pairs, 7–11 mm long, 3–6 mm wide, glabrous above, beneath with white appressed hairs. Inflorescence racemes, 1–2cm long, densely 5 to 10-flowered; peduncles erect, 5–9 cm long, covered with white and black hairs, sulcate; bracts narrowly lanceolate to lanceolate, shorter than calyx, 2–3 mm long, 1.0–1.5 mm wide, loosely covered with black hairs; pedicels ca. 1 mm long, black hairy. Calyx 5–6 mm long, campanulate, not oblique, loosely to rather densely covered with black hairs; teeth 1–2 mm long, narrowly triangular. Corolla yellow or pale yellow; standard 12–14 mm long, distinctly longer than other petals, the lamina elliptic, emarginate at apex, attenuate to claw, reflexed in middle part; wings ca. 9 mm long including the claw (claw ca. 3.5 mm), the lamina oblong, retuse at apex; keel ca. 8 mm long including the claw (claw ca. 4 mm long), the lamina ca. 3 mm long, subobtuse at apex; ovary subsessile, ellipsoid, glabrous.

  • Distribution: Endemic in Korea. Hamgyeongbuk-do, Hamgyeongnam-do. Growing on high mountains of North Korea.

Note: Although this species was first recorded from Seolryeong Mountain of Hamgyeongbuk-do (Nakai, 1919), little is known about its taxonomic position or morphology. Initial diagnostic characters presented in the protologue for this species included ovaries that were glabrous when compared with a similar congener, A. frigidus (L.) A. Gray (Nakai, 1919). However, some ovaries of A. frigidus can be glabrous even though most are usually pubescent (Podlech and Zarre, 2013). Therefore, this character is not reliable for separating the two species. Nevertheless, A. setsureianus is readily distinguished from A. frigidus in its gross morphology, e.g., for leaflet, bract, stipule, calyx, corolla, and legume (Table 1). If one takes into account all of those different morphological combinations, we can then argue that A. setsureianus must be accepted as an independent species, in accordance with an earlier treatment by Podlech and Zarre (2013). Alternatively, Korean plants can be inferred as part of a speciation process represented along the distributional margins of an A. frigidus complex widely distributed in countries of northern Eurasia (i.e., Europe to Japan).
When describing A. setsureianus, Nakai (1919) stated that the keel was 15 mm long. This was also included in the Korean flora of Im (1998). In contrast, we found that the keels from type and other specimens collected from the Mt. Seollyeong measured ca. 8 mm long (Fig. 3). Other morphological descriptions for this species were also ambiguous, especially for fruit characters. This might have resulted because geopolitical positioning reduced the availability of plants that are endemic to North Korea. Therefore, we are presenting an amended full description that relies upon a limited number of specimens.

  • Korea: Growing on high mountains of North Korea and cultivated in North and South Korea.

Note: Taxonomic study of two varieties of A. mongholicus (var. dahuricus and var. nakaianus) was conducted by Choi et al. (2013). Two other intra-specific taxa have been designated within the A. mongholicus complex, i.e., A. membranaceus Fisch. var. manshuricus Nakai (1918) and Astragalus membranaceus Bunge f. albiflorus Y.N. Lee (1996b). However, these two are not validly published.
Astragalus membranaceus var. manshuricus has been accepted as a Korean species (Chung, 1957; Lee W., 1996; Lee Y., 1996; Im, 1998; Lee, 2006) since Nakai listed this for the Flora of Baekdu Mountain (1918). Because that first listing did not present any description or diagnostic characters, it is considered as merely a designation (i.e., nom. nud.) rather than a named species (ICN Art. 38.1, McNeill et al., 2012). Thus, we excluded this designation from the Korean Astragalus. Furthermore, our examination revealed that the description and illustration made for this designation by Chung (1957) do not belong to a species within Astragalus but instead refer to Hedysarum vicioides Turcz. var. japonicum (Fedtsch.) B.H. Choi & H. Ohashi. The investigation of Chung’s collection preserved at the SKK herbarium also confirmed that A. membranaceus var. manshuricus sensu Chung (1957) is in fact Hedysarum vicioides var. japonicum. Hence, the posterior Korean flora (Lee W., 1996; Lee Y., 1996b; Lee, 2006) to Chung (1957) also followed that mistake.
In the absence of a type specimen, Lee Y. (1996) described the plant with whitish flowers found at Baekdu Mountain as A. membranaceus f. albiflorus Y.N. Lee. Thus, this designation failed to fulfill the requirements for valid publication (ICN Art.40.1, McNeill et al., 2012). The valid publication is needed if we are to accept this plant as a new forma of A. mongholicus. However, an examination of A. membranaceus f. albiflorus photographed by Lee Y. (1996; 2006) showed that the plant may not even be a member of the Astragalus genus. Hence, we do not acknowledge this designation as a Korean Astragalus species.
