栉叶蒿属 zhi ye hao shu
Shi Zhu (石铸 Shih Chu); Christopher J. Humphries, Michael G. Gilbert
Herbs, annual or perennial. Leaves alternate, pectinate to pinnatisect. Synflorescence of short axillary spikes grouped into a
slender, leafy panicle. Capitula rather small, heterogamous, disciform. Involucre ovoid or broadly ovoid; phyllaries in 3 or 4 rows,
scarious margins broad. Receptacle narrowly conical, epaleate. Marginal florets usually 3 or 4, female, fertile; corolla narrowly
tubular, apex not toothed. Disk florets of two kinds; outer bisexual, inner completely male with reduced ovaries; all central florets
with corolla apex 5-lobed. Anther bases obtuse; apical appendage rhomboid-acuminate. Style branches linear. Achenes in a row
around base of receptacle, ellipsoid, somewhat compressed or triquetrous, brown, striate. Corona absent.
One species: China, Kazakhstan, Mongolia, Russia.
Molecular data (Watson et al., BMC Evolutionary Biology; http://www.biomedcentral.com/1471-2148/2/17/; accessed 10 Apr 2011) indicate
that Neopallasia is closely related to Seriphidium s.s. and could be included with that genus within a more broadly conceived Artemisia.

Artemisia pectinata Pallas, Reise Russ. Reich. 3: 755.
1776; A. pectinata var. yunnanensis Pampanini; A. yunnanensis
(Pampanini) Krascheninnikov (1958), not Jeffrey ex Diels (Jun
1912), nor H. Léveillé (Nov 1912); Neopallasia tibetica Y. R.
Ling; N. yunnanensis (Pampanini) Y. R. Ling.
Herbs, 12–40 cm tall; stems erect, unbranched or branched
from base, purplish, ± densely white sericeous. Lower and middle
stem leaves sessile; leaf blade oblong-elliptic, 1.5–3 ×
0.5–1 cm, both surfaces green, glabrous, sometimes with sessile
glands, pectinately pinnatisect; segments linear-subulate, somewhat
rigid. Upper stem leaves to below synflorescence similar,
but smaller. Synflorescence of short axillary spikes grouped into
a slender, leafy panicle. Capitula many, rather small, sessile.
Involucres ovoid or broadly ovoid, 2.5–3 mm in diam.; phyllaries
in 3 or 4 rows, abaxially glabrous, scarious margin
broad, outer ones somewhat short, inner ones rather narrow.
Marginal female florets 3 or 4, fertile, narrowly tubular, without
apical teeth. Disk florets tubular, 5-lobed, of two kinds:
outer bisexual, inner completely male with reduced ovaries.
Achenes brown, elliptic, 1.2–1.5 mm, somewhat compressed.
Deserts, gravelly places of river valleys, wastelands; 1300–3400
m. Gansu, Hebei, Heilongjiang, Jilin, Liaoning, Nei Mongol, Ningxia,
Qinghai, Shanxi, Sichuan, Xinjiang, Xizang [Kazakhstan, Mongolia,
Russia].
Neopallasia pectinata is a highly variable species, and the Chinese
entities N. tibetica and N. yunnanensis seem best treated as synonymous
with it.
156. ALLARDIA Decaisne in Jacquemont, Voy. Inde 4(Bot.): 87. 1841.
扁毛菊属 bian mao ju shu
Shi Zhu (石铸 Shih Chu); Christopher J. Humphries, Michael G. Gilbert
Waldheimia Karelin & Kirilov.
Herbs, perennial, glabrous to densely tomentose. Leaves alternate, closely spaced, sometimes rosulate, spatulate or cuneate,
apex 3–5-lobed or -parted, or oblong, pinnatisect or pinnatipartite. Capitula solitary, pedunculate, heterogamous, radiate. Involucre
hemispheric; phyllaries in 3 or 4 rows, scarious margins dark brown. Receptacle convex, epaleate. Marginal florets in 1 row, female
or neuter, usually sterile; lamina pink, white, or bluish violet. Disk florets many, yellow or bluish violet, bisexual, fertile; corolla
tubular, apex 5-lobed. Anther bases obtuse, apical appendage ovate-lanceolate. Style branches linear, apex truncate. Achenes somewhat
curved, faintly 5–10-ribbed, generally with sessile glands, sometimes pilose. Corona of 20–50 bristlelike scales, with flat and
palmate base, apex brownish, sometimes wider.
Eight species: Afghanistan, China, India, Kazakhstan, Mongolia, Nepal, Pakistan, Russia, Tajikistan, Uzbekistan; eight species (one endemic) in
China.
The exact date of publication of Allardia is uncertain, but such evidence as there is (Zain-ul-Abidin, Biologia 4: 212–214. 1958) suggests that it
was in 1841, thus predating Waldheimia, which was published in 1842.
