Type: — China. Hupeh (= Hubei): Ichang (= Yichang ), A. Henry 6764 (lectotype designated here, P00705765 !; isolectotypes K000778200 !, K000778201 !, K000778202 !, BM000598141 !, BM000598142 !, P00705766 !, HUH00006077!) .

Description:—Herbs 60–100 cm tall, perennial. Stem erect, branched above, ribbed, unwinged, glabrous or with sparse long multicellular hairs. Leaves concolorous, surface green, smooth, with sparse multicellular hairs along veins or glabrous, basal and lower cauline leaves petiolate; leaf blade oblanceolate, or ± narrowly elliptic, 10–20 × 4–6 cm, pinnatilobate; segments 4–7 pairs, elliptic, margin with 1–3 mm spine. Middle and upper cauline leaves similar but sessile and semiamplexicaul and gradually smaller upward. Capitula corymbose, nodding. Involucre campanulate, ca. 3–4 cm in diam., glabrous. Phyllaries in ca. 7 rows, green, lacking wings and scarious appendage, all of similar length; outer and middle phyllaries lanceolate or linear, pectinately fringed with dense spinules, apex narrowed into a spinule; inner phyllaries linear, not spinulose. Florets bisexual. Corolla white, ca. 1.3 cm, tube ca. 0.7 cm. Achene brownish, ca. 4 mm. Pappus bristles brownish, to 1.2 cm.

Phenology:— Flowering from July to September.

Distribution and habitat:— Cirsium henryi is distributed in western Hubei, China. It grows in roadside and open meadow at elevations between 1800 –2700 m above sea level.

Notes:— In the protologue of Cirsium henryi, Franchet (1897) cited only one collection, i.e. Henry 6764, but he did not specify the herbarium in which this collection was preserved. Thus the eight specimens of this collection, three kept in K, two in P, two in BM and one in HUH, should be regarded as syntypes. Here we designate one sheet in P (P00705765; Fig. 1 A ) as the lectotype of C. henryi.
