Type:— CHINA. Sichuan province: Hanyuan county, Tahsiangling (= Daxiangling), on western mountain slopes, 19 September 1934, H. Smith 13540 [lectotype UPS (V-083129)!, designated here; isolectotypes A00002754!, A00124146!, BM000945899!, F (1482747)!, GB-0047183!, MO (herb. nos. 1626714, 1626728)!, PE00029953!, PE00421991!, S08-6031!, W 1940-0013606!; see below for a discussion]. Fig. 3 View FIGURE 3 .

Description:—Herbs, perennial, 20–150 cm tall. Rhizome woody, to 0.5 cm in diameter at base. Stems more or less branched, erect or ascending, pubescent or glabrous, reddish-brown or green. Basal stem leaves usually withered before anthesis, subsessile; middle stem leaves more or less sessile, leaf blade ovate, ovate-oblong or oblong, 4–20 cm long, 2.5– 6 cm broad, adaxially glabrous or sparsely pubescent, abaxially tomentose, 2- or 3-pinnatisect, segments 2–6 on each side, ovate-elliptic or oblong, lobules linear or linear-lanceolate, 8–25 (–35) mm long, 2.5–3.5 mm broad, rachis narrowly winged, apex acuminate, margin serrate, incised or entire, rarely revolute; uppermost leaves 1- or 2-pinnatisect, lobules linear or linear-lanceolate, margin serrate, incised or entire. Synflorescence a dense or sparse panicle. Capitula campanulate, subsessile, usually clustered together, 4–7 mm long, 2–4 mm broad. Leaflike bracts linear or linear-lanceolate; phyllaries oblong-ovate or ovate, whitish, midribs green when fresh, margin membranous. Marginal female florets 6–12, white, fertile, 4–6 mm long, corolla tubular, apex 2- or 3-toothed, style exerted; disk florets 10–20, white, bisexual, fertile, 4–6 mm long, corolla tubular, apex 5-toothed. Achenes oblong.

Distribution and habitat:— Artemisia fulgens is distributed in western and southwestern Sichuan and northeastern Yunnan, China ( Fig. 12 View FIGURE 12 ). It grows by roadsides, at forest margins or on mountain slopes at altitudes of 1000–3600 m.

Phenology:—Flowering from August to November; fruiting in November.

Lectotypification:—In the protologue of Artemisia fulgens, Pampanini (1930a) cited a single collection A.E. Pratt 88 (B, BM, E, K). As discussed by McNeil (2014), these sheets are syntypes as Pampanini (1930a) did not designate a type for A. fulgens . We have been able to trace two sheets from E and K. Both are well preserved and match with the original description. According to ICN Art. 9.3 ( Turland et al. 2018), we have chosen the E sheet, on which the specimens are complete, as the lectotype of A. fulgens ( Fig. 1A View FIGURE 1 ), and cited the remaining duplicates as isolectotypes (the K sheet shown in Figure 1B View FIGURE 1 ). We did not see the B and BM sheets.

In the protologue of Artemisia flaccida, Handel-Mazzetti (1938) cited a single collection, H. Smith 13540. Eleven duplicates are deposited at A, BM, F, GB, MO, PE, S, UPS and W, respectively (four sheets shown in Figure 3 View FIGURE 3 ). They are all well preserved and match with the original description. Handel-Mazzetti (1938) did not designate a type for A. flaccida in the protologue, although in 1937 he annotated the UPS and S sheets as “ Artemisia flaccida Hand. - Mzt., spec. nov., Typus” on the determination slips ( Fig. 3A, B View FIGURE 3 ). As discussed by McNeil (2014), all the sheets of the collection H. Smith 13540 are syntypes. We have designated the UPS sheet, with a photograph of it in the protologue, as the lectotype of A. flaccida , and cited the duplicates at A, BM, F, GB, MO, PE, S and W as isolectotypes.

Notes:—In the protologue, Pampanini (1930a) referred Artemisia fulgens to A. sect. Abrotanum Besser (1829: 222) . Handel-Mazzetti (1938) also referred it, under the name A. flaccida , to this section. Ling (1991) and Ling et al. (2011) placed this species within A. sect. Artemisia . Indeed, A. fulgens is similar to species in this section in having 1- or 2-pinnatisect leaves and linear or linear-lanceolate lobules, but actually this species should be closer to those in A. sect. Albibractea Ling (1980: 506) by having whitish phyllaries and white florets, and thus may better be placed within this section. In A. sect. Albibractea, A. fulgens is most closely similar to A. lactiflora Wallich ex Candolle (1938: 115) in having 1- or 2-pinnatisect leaves and campanulate capitula, but differs by having abaxially tomentose (vs. sparsely pubescent or glabrous) leaves, and entire, serrate or incised (vs. irregularly serrate) lobules. In the shape of leaf lobules, A. fulgens var. meiguensis (= A. flaccida var. meiguensis ) is rather similar to A. lactiflora var. incisa ( Pampanini 1927: 675) Ling & Ling in Ling (1988a: 42). The leaf lobules of the former are serrate or incised, whereas those of the latter are irregularly serrate. Geographically A. lactiflora is distributed in southern China, including Chongqing, Fujian, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangsu, Jiangxi, Sichuan and Zhejiang, partly overlapping with A. fulgens in distribution. Molecular work is needed to confirm the sectional placement of A. fulgens .
