in upper part and on synflorescence branches. Basal and lower
stem leaves withered by anthesis; middle stem leaves: petiole

2-pinnatipartite; primary lateral segments 2 or
3(or 4) pairs; ultimate lobes elliptic. Upper stem leaves small,
tripartite or entire. Synflorescence a lax or dense cyme. Capitula
1–1.5 cm in diam. Involucres cup-shaped, 5–7 mm in
diam.; phyllaries in 5 rows, margin white or pale brown scarious,
outer ones linear or linear-oblong, ca. 2.5 mm, abaxially
sparsely pilose, middle and inner ones ovate, narrowly elliptic,
or oblanceolate, ca. 4.5 mm. Ray florets yellow; lamina 1–7.5
mm. Achenes 1.2–1.5 mm. Fl. and fr. May–Nov. 2n = 18*, 36*.
Mountain slopes, rocks, river valleys, riverbanks, wastelands, hilly
lands; 600–2800 m. Anhui, Gansu, Guizhou, Hebei, Hubei, Jiangsu,

The infraspecific taxonomy of Chrysanthemum lavandulifolium
needs more detailed investigation. Dendranthema lavandulifolium
(Fischer ex Trautvetter) Kitamura var. aromaticum (Q. H. Liu & S. F.
Zhang) S. J. Zhou & D. K. Zang (Bull. Bot. Res., Harbin 16: 297. 1996;
D. indicum (Linnaeus) Des Moulins var. aromaticum Q. H. Liu & S. F.
Zhang, J. Wuhan Bot. Res. 1: 237. 1983; C. indicum Linnaeus var.
aromaticum (Q. H. Liu & S. F. Zhang) J. M. Wang & Y. T. Hou, Guihaia
30: 816. 2010), described from Hubei (Shennongjia), with ray floret
lamina 3.5–4 mm, appears to be somewhat intermediate between C.
lavandulifolium var. discoideum and C. lavandulifolium var. lavandulifolium,
and it reportedly differs from both by the aromatic, minutely
glandular, abaxial leaf surface.
