            <p> Phedimus daeamensis T.Y. Choi &amp; D.C. Son sp. nov.</p>
            <p>Fig. 1</p>
            <p>Type.</p>
            <p>  Republic of Korea.  Gangwon-do ,  Inje-gun ,  Buk-myeon , Wolhak-ri, Mt. Daeam. Elevation 1,000 m. 20 August 2014. K.H. Lee &amp; S.K. So 0001 (holotype KH; isotypes 2 sheet, KH)  . </p>
            <p>Perennial herbs.</p>
            <p> Rhizome woody, elongated. Roots not tuberous; rootstock not robust. Stems numerous, more basally branched, tufted, creeping, ascending, 12-21 cm long, glabrous. Leaves alternate, sessile, coarsely arranged; leaf blade obovate, 1-2.3 cm long, 0.5-1.2 cm wide, flat, base narrowly cuneate, margin apically to mid serrate 4-5  × , entire at base, apex obtuse; lower leaves almost all entire. Inflorescence corymbiform-cymose, many-flowered; bracts leaf-like. Flowers bisexual, mostly 5-merous, shortly pedicelled. Calyx tube 2.1-3.2 mm long; lobes spurless, lanceolate, 1-1.2 mm long, apex obtuse. Petals free, yellow, lanceolate to oblong, 5-6.5 mm long, abaxially keeled, apex acuminate, spreading at anthesis. Stamens 10, in 2 series, erect, shorter than petals, those opposite to petals adnate to them to 1/4 of length from the base; anthers red, ellipsoid, ca. 1 mm long; filaments yellow. Pistils 4.5-5 mm long; ovaries ca. 2.5 mm long, connate at the base; styles slender, 2-3 mm long. Carpels 5, erect, equaling or slightly shorter than the petals, adaxially gibbous, shortly connate at the base. Follicles greenish, stellately and horizontally spreading, ca. 4 mm long, with a very short beak. Seeds 0.8-0.9 mm long, brown, obovoid, scalariform, ribbed, striate. </p>
            <p>Flowers in May to June, fruiting in July to August.</p>
            <p>Distribution and habitat.</p>
            <p>Republic of Korea (Prov. Gangwon). Stony cliffs and rock crevices, at ca. 1000 m.</p>
            <p>Etymology.</p>
            <p> The specific epithet, " daeamensis ", is based on the name of the location, Mt. Daeam, where  Phedimus daeamensis was discovered. </p>
            <p>Korean name.</p>
            <p>Dae-am-gi-rin-cho.</p>
            <p>Molecular diagnosis.</p>
            <p> In total, 32 sequences of two DNA regions (ITS and psb A- trn H IGS) were newly obtained from the 16 accessions of  P. daeamensis and the six most closely related taxa (Suppl. material 1: Table S3). We also used 15 sequences from eight accessions obtained from GenBank (  P. aizoon var. floribundus ,  P. latiovalifolius ,  P. takesimense ) for the phylogenetic analysis. The lengths of the ITS and psb A- trn H IGS alignment were 588 and 272 base pairs, respectively (Table 2). After an alignment of 24 accessions, we found 173 variable sites and 144 of these were parsimony informative (Table 2 and Suppl. material 1: Table S6). Overall, the GC ratio was 50.5% and 22.5% for ITS and psb A- trn H IGS, respectively (Table 2). K2P genetic distances among in-group individuals ranged from 0 to 0.043 (mean 0.023) for ITS and 0 to 0.048 (mean 0.018) for psb A- trn H IGS (Table 2). We also found a 6 bp inversion in the psb A- trn H IGS of all  P. daeamensis accessions and one accession of  P. takesimensis (Suppl. material 1: Table S6). We excluded this inversion from further phylogenetic analysis. </p>
            <p>* Out-group taxa excluded.</p>
            <p> Overall, the inferred phylogenies from the two regions differ, particularly in the basal nodes (Figs 2, 3). There was a congruence between the ML and BI trees inferred from the ITS and psb A- trn H IGS data sets (Figs 2, 3, Suppl. materials 2, 3: Figs S1, S2; posterior probabilities are indicated in ML trees). In the psb A- trn H IGS trees,  P. daeamensis was separated but formed an unresolved polytomy (Fig. 3 and Suppl. material 3: Fig. S2).  Phedimus sikokianus formed a monophyletic group, whereas all other species showed more complicated and mixed clustering patterns (Fig. 3 and Suppl. material 3: Fig. S2). In the ITS trees, two major clades were recognized, but only clade 1 was statistically robust (Fig. 2 and Suppl. material 2: Fig. S1). The three samples of the putative new species,  P. daeamensis , formed a well-supported monophyletic clade (bootstrap value; BS = 95%; posterior priority; PP = 0.99) that was separated from the other species.  Phedimus daeamensis again formed a clade together with  P. middendorffianus (one sample) and  P. takesimensis (three samples), but the statistical support was very weak (Fig. 2 and Suppl. material 2: Fig. S1). All accessions of  P. sikokianus formed a well-supported clade (BS = 95.9%; PP = 0.99) with samples of  P. kamtschaticus and  P. aizoon , both of which were not monophyletic (Fig. 2, Suppl. material 2: Fig. S1).  Phedimus latiovalifolius was nested within a clade containing samples of  P. kamtschaticum and  P. aizoon (Fig. 2). </p>
