9. Tribe ANTHEMIDEAE

758
ANTHEMIDEAE
Receptacle conical, hollow, epaleate. Marginal florets female, fertile; lamina when present white, usually absent in Chinese material.
Disk florets yellow or reddish, bisexual, fertile; corolla tubular, inflated at base, apex 5-lobed. Anther appendages ovoid, almost 1/2
as long as anthers. Achenes circular to slightly dorsiventrally compressed in cross section, with 3–5 adaxial ribs, with multicellular
hairs between ribs. Corona lacerate or fimbriate, slightly longer adaxially. x = 7.
Five species: Afghanistan, China, Kazakhstan, Kyrgyzstan, Pakistan, Turkmenistan; SW Asia (Iran); one species in China.

Akad. Nauk S.S.S.R., Ser. 1, Fl. Sist. Vyssh. Rast. 3: 345. 1937.
Herbs, annual, 3–15 cm tall; stems simple or branched
from base, sparsely white lanate. Leaves succulent, petiolate;
leaf blade (0.8–)1–2(–3) × (0.3–)0.5–0.7(–1) cm, pinnate,
sparsely grayish lanate; segments linear-lanceolate, apex acute;
uppermost leaves linear. Capitula solitary; peduncle long, apically
thicker, pubescent. Involucre very broadly obconical, 4–
10 mm wide; phyllaries linear-oblong, slightly recurved, green,
margin narrowly membranous. Marginal florets usually absent,
white when present; usually florets all tubular, lemon-yellow,
slightly constricted in middle but not inflated below this, exserted
from involucre. Achenes 1–1.5 × 0.25–0.5 mm, abaxially
slightly convex, adaxially with 3 or 4 obscure ribs, densely
white scaly in broader part. Corona oblique, to 0.5 mm, not
deeply lacerate, lobes acuminate.
Xinjiang (Tian Shan) [Kazakhstan, Kyrgyzstan, Turkmenistan].
Microcephala subglobosa is atypical of the genus as a whole,
which usually has prominent ray florets and disk florets that are obviously
inflated at the base. It is known from China by only a single
gathering.

太行菊属 tai hang ju shu
Shi Zhu (石铸 Shih Chu); Christopher J. Humphries, Michael G. Gilbert
Herbs, perennial, with somewhat woody stem basally. Leaves pinnatisect. Capitula heterogamous, radiate, 1–3 at apex, corymbose.
Involucres cup-shaped; phyllaries in 4 rows, with broad scarious margins. Receptacle convex to conical, epaleate. Ray florets
in 1 row; lamina white or pink. Disk florets many, bisexual, yellow, tubular, 5-lobed. Anthers obtuse at base, with apical lanceolate
appendage. Style branches linear, apex truncate. Achenes obovoid, 3- or 4-ribed. Pappus represented by 4–6 separate, unequal,
mainly abaxial subulate scales.

Herbs, perennial, 10–30 cm tall; stems ascending, purplered
or brown, densely or sparsely appressed pubescent, base
somewhat woody. Basal leaves: petiole more than 0.5 cm; leaf
blade ovate, broadly ovate, or elliptic, 2.5–3.5 × 2–2.5 cm, 1- or
2-pinnatisect, both surfaces sparsely pubescent or glabrous; primary
lateral segments 2- or 3-paired; ultimate segments linear,
falcate, lanceolate, or obliquely triangular. Stem leaves similar
to basal leaves; uppermost leaves pinnatifid. Capitula 1–3 at
apices of branches. Involucre coryliform, ca. 1.5 cm in diam.,
abaxially glabrous or nearly so; phyllaries in 4 rows, abaxially
rather densely pubescent, outer and middle phyllaries linear or
oblanceolate, 4–5.5 mm, inner ones narrowly elliptic, 6–7 mm.
Ray florets white or pink; lamina linear, ca. 2 cm, apex 3-denticulate.
Disk florets yellow, 5-lobed. Achenes obovoid, ca. 1.2
mm, 3–5-ribbed. Corona scales 4–6, mainly abaxial.
● On rocks of mountain slopes, cliffs; 800–1200 m. Hebei, Henan,
Shanxi.
The capitula are used to treat diseases of the liver.
