Herbs, perennial. Stems 30-150 cm, erect, corymbosely branched above middle or only in upper part, pilose, especially in upper part and on synflorescence branches. Basal and lower stem leaves withered by anthesis; middle stem leaves: petiole 0.5-1 cm; leaf blade ovate, broadly ovate, elliptic-ovate, narrowly elliptic, or ovate-lanceolate, 2-7 × 1.5-4.5 cm, surfaces concolorous or nearly so, 2-pinnatisect, 2-pinnatipartite, or inconspicuously 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*.

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.
