9. Artemisia finita Kitagawa (1942: 124) ≡ Seriphidium finitum (Kitagawa) Ling & Y.R. Ling in Ling (1980: 513). Type:— CHINA. Inner Mongolia: Hulunbuir, dry gravel grassland, 27 August 1940, M. Kitagawa s.n. (holotype: TI00080705!); Paratype:— CHINA. Inner Mongolia: Hulunbuir, dry gravel grassland, 24 August 1940, M. Kitagawa s.n. (TI00081468!).

Perennial herbs or subshrubs, 20–60 cm tall. Stems few, sparsely single, often with numerous short nutritional stems, branching from the middle, branches 4–10 cm long, obliquely pointing upwards. Lower stem leaves oblong-ovate or oblong, 2–3-pinnatisect, 2–5 cm long, 1–2 cm wide, petiole 2–5 cm long, with 3–5 segments per side, segments further pinnatisect, lobules narrowly lanceolate, 3–13 mm long, 1–1.5 mm wide, apex obtuse-acuminate. Middle stem leaves ovate, 1–2-pinnatisect, 2–3.5 cm long, 1–1.5 cm wide, nearly sessile, with pinnatifid pseudostipules. Upper stem leaves pinnatisect or trifid, with narrowly lanceolate lobes. The grayish-white tomentum on the stems and branches partially sheds at maturity, the tomentum on all leaves persists, and the leaves have a slightly soft texture, while the lower and middle stem leaves usually wither. Capitula oblong-obovoid or oblong, 2–4 mm long, 2–2.5 mm in diameter. Synflorescence a narrow or somewhat broad panicle. Phyllaries in 4–5 series, outer phyllaries small, ovate, middle phyllaries oblong-ovate, both outer and middle phyllaries dorsally covered with the grayish-white tomentum, margins membranous, inner phyllaries oblong-ovate or long-obovate, semi-membranous, dorsally sparsely tomentose or nearly glabrous. Bisexual florets 3–13, corolla yellow. Anthers linear, appendages linear, base obtuse. Style subequal to corolla, tips truncate, with cilia. Achenes with inconspicuous fine longitudinal lines, obovoid.

Distribution and habitat:—This species is only distributed in northeastern Inner Mongolia, China ( Figure 10 ). It grows in rocky slopes, semidesert steppes, riverbanks, and lakeshores at low to mid elevations.

Phenology:—Flowering and fruiting from August to October.

Taxonomic notes:—In the protologue of Artemisia finita, Kitagawa (1942) cited three gatherings from Inner Mongolia, China: Y. Fukuda s.n. (August 1938), M. Kitagawa s.n. (24 August 1940), and M. Kitagawa s.n. (27 August 1940), designating the latter as the type without specifying the herbarium. We have traced one sheet each of M. Kitagawa s.n. (24 August 1940: TI00081468) and M. Kitagawa s.n. (27 August 1940: TI00080705) at TI, both of which have the collection information mentioned in the protologue and match well the original description. Therefore, according to Arts. 9.1 and 9.7 of the ICN ( Turland et al. 2018), sheet TI00080705 should be regarded as the lectotype, and the other sheet as the paratype.
