匍枝蒲儿根 pu zhi pu er gen

Herbs, long stoloniferous or not stoloniferous, with leafy stems. Rhizomes 6-10 mm in diam., clad in persistent petiole bases; stolons slender, distally leafy or remotely leafy at nodes. Stems 1(-3), erect, 30-80 cm tall, to 6 mm in diam. at base, not branched below synflorescence, sparsely arachnoid, fulvous villous, or glandular. Radical leaves several, rosulate, long petiolate; petiole 6-15 cm, sparsely to densely villous or glandular with long hairs, rarely subglabrous, basally expanded; blade abaxially pale green, adaxially green, ovate-cordate, broadly ovate, or reniform, 2.5-21 × 3-22 cm, papery, abaxially sparsely pubescent or glabrous, adaxially sparsely fulvous puberulent, palmately veined, base deeply to shallowly cordate, margin palmately 3-5-lobed; lobes broadly deltoid, mucronulate, apex obtuse-acuminate-mucronulate. Stem leaves usually 3-5, similar to radical ones, progressively smaller upward and shorter petiolate. Capitula 2-3 cm in diam., (2-)5-15 arranged in terminal and axillary subumbelliform corymbs; peduncles 2-13 cm, not bracteate, slightly dilated at apex, sparsely fulvous villous, puberulent, or glandular pilose, rarely subglabrous. Involucres obconic-campanulate, 6-7 × 3-8 mm, not calyculate; phyllaries ca. 13, oblong, 1.5-2 mm wide, fulvous villous, glandular villous, pilose, or glabrescent, obscurely 3-veined, apically obtuse to rather acute, ciliate in upper part. Ray florets 13, uniseriate; corolla tube 2-2.5 mm, glabrous; lamina yellow, oblong or oblong-elliptic, 10-11 × 3-4 mm, 4-veined, apically 3-denticulate, obtuse. Disk florets many; corolla yellow, ca. 4 mm, with 1.5-1.8 mm tube and campanulate limb; lobes oblong-lanceolate, ca. 1 mm. Anthers oblong, 1.5-2 mm, basally obtuse; appendages ovate-lanceolate. Style branches recurved. Achenes cylindric, ca. 2 mm, smooth, glabrous. Pappus absent. Fl. Apr-Jun, fr. May-Jul. 2n = 48*, 72*.

● Wet shaded places, streamsides, woods, roadsides, forest margins; 500-2100 m. Chongqing, Guizhou, W Hubei, Hunan, Jiangxi, E Sichuan, N Yunnan.

Sinosenecio globiger resembles S. phalacrocarpus but differs by the stolons (if present), abaxial surface of leaves, and phyllaries not arachnoid-tomentose and the achenes glabrous.

1 Involucres 5-8 mm in diam.; indumentum of peduncles and phyllaries not glandular; stolons present and long, or absent, if present then usually not leafy in basal and middle parts, but densely leafy in upper part.   24a var. globiger
+ Involucres 3-5 mm in diam.; indumentum of peduncles and phyllaries glandular; stolons present but shorter, remotely leafy at nodes.   24b var. adenophyllus
