9. Tribe ANTHEMIDEAE

Achillea nobilis is apparently known from China only by a single
19th century gathering by Karelin and Kirilov. A similar record for the
ANTHEMIDEAE

European A. magna Linnaeus, which is not otherwise recorded from C
Asia, is most likely a misidentification of A. nobilis.
Shi Zhu (石铸 Shih Chu); Christopher J. Humphries, Michael G. Gilbert
Herbs, annual or perennial, or subshrubs; indumentum of medifixed hairs. Leaves alternate, pinnatisect to variously lobed, occasionally
entire. Synflorescences cymose; capitula solitary or in lax, ± flat-topped panicles, pedunculate, heterogamous and radiate,
rarely homogamous and discoid. Involucres usually ± hemispheric to ovoid; phyllaries in 3 rows, scarious margins narrow. Receptacle
convex to narrowly conical, paleate, rarely basally or completely epaleate; palea oblong or subulate, scarious, apex truncate or
acute to acuminate. Marginal florets in 1 row, female, fertile; lamina white or yellow [or rarely reddish]. Disk florets many, yellow,
rarely reddish, bisexual; corolla tubular, apex 5-lobed. Anther bases obtuse. Style branches truncate. Achenes oblong or obconic,
smooth to prismatic to 4 or 5(or 8)-ribbed, dorsiventrally compressed. Corona absent or shallow, often adaxially more developed
or forming an adaxial auricle.
About 100(–150) species: mainly in S Europe and SW Asia; one species (introduced) in China.
Anthemis arvensis Linnaeus (田春黄菊 tian chun huang ju) is cultivated in E China.

1. Anthemis cotula Linnaeus, Sp. Pl. 2: 894. 1753.
臭春黄菊 chou chun huang ju
Anthemis foetida Lamarck; Maruta cotula (Linnaeus) Candolle;
M. foetida (Lamarck) Cassini.
Herbs, annual, (15–)30–50 cm tall, fetid; stems erect,
corymbosely branched, sparsely pubescent or subglabrescent.
Leaves sessile; leaf blade ovate-oblong, 1.5–6 × 0.5–3 cm, 2pinnatisect;
ultimate segments narrowly linear. Capitula terminal,
solitary, long pedunculate, 1–2 cm in diam. Involucre hemi-
spheric; phyllaries in 3 rows, oblong, scarious margin narrow,
apex obtuse. Ray florets white; lamina 5–14 × 3–6 cm, elliptic.
Disk florets yellow, tubular, 5-lobed. Achenes oblong-turbinate,
1–1.5 mm, tuberculate, obscurely 8(–10)-ribbed. Corona absent.
Fl. and fr. Jun–Jul. 2n = 18.
Cultivated and possibly naturalized. Nei Mongol [native to N
Africa, SW Asia, and Europe; introduced elsewhere].
Anthemis cotula has been recorded as a weed from E Mongolia
and can be expected to behave similarly in China.

Gymnocline Cassini; Pontia Bubani; Pyrethrum Zinn.
Herbs, perennial, subshrubs, or shrubs, lower parts somewhat woody; indumentum absent or of basifixed and/or medifixed
hairs. Leaves alternate, rarely rosulate, pinnatifid to 3-pinnatisect, rarely entire. Synflorescences cymose, mostly flat-topped, sometimes
reduced to a solitary capitulum. Capitula heterogamous or homogamous, radiate, disciform or discoid. Involucres campanulate;
phyllaries in 3–5 rows, scarious margins broad or narrow, usually brown, less often white. Receptacle convex or flat, epaleate, usually
pilose. Marginal florets in 1, very rarely 2, rows, or absent, female, fertile; lamina white or red, less often yellow, or absent,
ovate, elliptic, or linear. Disk florets many, yellow, bisexual; corolla tubular, apex 5-lobed. Anther bases obtuse; apical appendage
ovate-lanceolate or broadly lanceolate. Style branches linear, apex truncate. Achenes terete or obscurely 3-angled, 5–10(–12)-ribbed,
often with sessile glands, never with myxogenic cells. Corona present, 0.1–0.4 mm, sometimes of free scales, rarely an adaxial
auricle (very rarely absent).
About 100 species: N Africa, C Asia, Europe; 19 species (two endemic, two introduced) in China.
Tanacetum partheniifolium (Willdenow) Schultz Bipontinus (Tanaceteen, 56. 1844; Pyrethrum partheniifolium Willdenow, Sp. Pl. 3: 2156.
1803, “parthenifolium”; 伞房匹菊 san fang pi ju), native to C and SW Asia, and T. parthenium (Linnaeus) Schultz Bipontinus (Tanaceteen, 55. 1844;
Matricaria parthenium Linnaeus, Sp. Pl. 2: 890. 1753; 短舌匹菊 duan she pi ju), originating within Europe, possibly through selection from T.
partheniifolium, are cultivated as ornamentals in China and are included in the following key. Tanacetum parthenium is used medicinally.
A gathering by Karelin and Kirilov from Xinjiang (“Sinkiang: Songaria-Kirghisici”), not seen by the present authors, has been named as
Pyrethrum achilleifolium M. Bieberstein (Fl. Taur.-Caucas. 2: 327. 1808; Tanacetum achilleifolium (M. Bieberstein) Schultz Bipontinus, Tanaceteen,
47. 1844), a C Asian species recorded west of the W Altai. It would key out below as T. santolina, from which it differs by its phyllaries broader,
pubescent only at their bases, and with broader membranous margins.
