Type:— CHINA. Xinjiang, Fukang, Bogda Ola , Tu-Shu-Shan, in the valley above the Haitze lake , ca. 2000 m, 25 Jul. 1928, P.K.Vorotnikoff 535 (holotype S (Herb. No. S-GH-5309!)). Fig. 1 View FIGURE 1 .

Description:—Herbs, perennial, usually caespitose, 20–50 cm tall, woody at base, arachnoid-pubescent or glabrescent. Stems brown or dark brown, shortly branched or not. Basal stem leaves usually sessile, sparsely pubescent or glabrescent, ovate-oblong or oblong, 3–5 cm long, 2–3 cm broad, 1- or 2-pinnatisect, segments 5–7 on each side, linear or linearlanceolate. Middle stem leaves ovate-elliptic or oblong, 2–5 cm long, 2–3 cm broad, 1- or 2-pinnatisect, segments 5–7 pairs, pectinate, linear or linear-lanceolate, 0.5– 1 cm long, 2–3 mm broad, lobules linear or lanceolate. Uppermost leaves and leaf-like bracts 1-pinnatisect, 3–5 segments on each side, linear or linear-lanceolate. Synflorescence a spike-like or raceme-like panicle. Capitula pedunculate or sessile, nodding, hemispheric or subglobose, 4–7 mm in diameter, phyllaries sparsely pubescent or glabrescent abaxially, with green midribs when fresh and membranous margin, receptacle hemispheric, pubescent. Marginal female florets 8–16, corolla vasiform or narrowly conical, 3- or 4-toothed. Disk florets 30–70, bisexual, corolla tubiform, 5-toothed. Achenes oblong or oblong- ovoid, usually with a minute apical crown.

Distribution and habitat:— Artemisia rupestris is widely distributed in Xinjiang, China ( Fig. 7 View FIGURE 7 ), and also in Eastern Europe, Kazakhstan, Kyrgyzstan, Mongolia, Russia, and Tajikistan ( Poljakov 1961, Ling 1991, Ling et al. 2011). It grows on dry hills, in desert or semidesert steppes, dry river valleys, or at forest margins at altitudes of 1100–4600 m.

Phenology:—Flowering from July to August; fruiting from August to October.

Notes:— Wei (1999) and Wu (2008) specifically recorded the distribution of Artemisia rupestris , under the name of A. argyrophylla var. brevis , in Ruoqiang county in Xinjiang, China, without citing any specimen. However, we have been unable to trace any specimen referable to this variety (or A. brevis ) from this county in the major relevant Chinese herbaria, including HNWP, NWTC, PE, WUK, and XJBI. Further research and filed work are needed to verify the distribution of this species in Ruoqiang.
