Description:—Perennial herbs. Roots fibrous, distally thicker, up to 3 mm in diameter. Stem 20‒60 cm tall, usually basally branched, distally glandular-pubescent, with bulbils borne in leaf axils at late flowering and fruiting stage. Leaves 2‒3-ternate; blade triangular, 5‒15 cm long and broad; leaflets ovate, broadly ovate, obovate, or suborbicular, 0.5‒ 4 cm long, 0.6‒ 5 cm broad, papery, abaxially glandular-pubescent when tender, both sides glabrous when mature, green on adaxial side, pale green on abaxial side, base rounded or subcordate, apex obtuse, 3-lobate; lobes crenatedentate; veins slightly submerged adaxially, raised abaxially; petiole slender, 1.5‒ 6 cm long; stipule membranous, ovate-orbicular, margin torn. Inflorescence a compound cyme, few-flowered, corymbiform. Pedicels 0.5‒ 2 cm long, glandular-pubescent. Flowers bisexual, erect. Sepals 4, elliptic or obovate, caducous, 3‒4.5 mm long, 2‒2.5 mm broad, white or tinged with purplish, glabrous or abaxially very sparsely glandular-pubescent. Stamens 40‒60, 5‒7 mm long; filaments narrowly clavate, 4‒6 mm long, whitish or purplish; anthers oblong, 1‒1.2 mm long, ca. 0.6 mm broad, apex obtuse, whitish. Carpels 3‒6, sessile, 1.2‒ 2 mm long; ovaries fusiform, shallowly ribbed, ca. 1 mm long, subglabrous; styles 0.6‒ 1 mm long, slightly recurved at apex; stigmas conspicuous, linear, ca. 0.5 mm long. Achenes sessile, 3.5‒ 5 mm long, sparsely glandular-pubescent; body fusiform, profoundly ribbed; styles persistent, recurved at apex.
Phenology:—Flowering from March to May; fruiting from April to June.
Distribution and habitat:— Thalictrum fortunei is currently known to occur in southern Anhui, eastern Hubei, northern Jiangxi, southern Jiangsu and Zhejiang provinces, China ( Fig. 9 View FIGURE 9 ). The previous records of its distribution in Fujian province ( Lin & Zhao 1985, Wang 2000) and in Henan province ( Anonymous 1981) should have resulted from misidentifications, and thus are doubtful (see below). This species grows in forests, along streams, on damp rocks in ravines or on slopes at elevations of 10‒600 m above sea level.

Notes:—Our molecular systematic studies based on nrDNA ETS and ITS and cpDNA trn V- ndh C sequence data of 115 species, with 84 from China ( Zeng 2022), indicate that Thalictrum fortunei is most closely related to T. ramosum Boivin (1945: 115), a species widely distributed in China (Chongqing, Guangxi, Guizhou, Hubei, Hunan, Sichuan, Yunnan). Morphologically these two species are somewhat similar in habit and share an array of other characters, including caducous sepals, narrowly clavate filaments, apically recurved styles and sessile, fusiform achenes.
Because of their superficial morphological similarity and somewhat overlapping geographical distribution, Thalictrum fortunei has been sometimes confused with T. fargesii . Some specimens of the latter species from Anhui, Henan, Jiangxi and Zhejiang provinces were misidentified as T. fortunei ( Fig. 10 View FIGURE 10 ). As shown in Figures 5‒7 View FIGURE 5 View FIGURE 6 View FIGURE 7 , 11 View FIGURE 11 , 12 View FIGURE 12 , T. fortunei is similar to T. fargesii in having 2‒3-ternate leaves, usually broadly ovate leaflets, few-flowered inflorescence, clavate filaments of stamens, and fusiform achenes, but differs by the presence (vs. absence) of bulbils in leaf axils at late flowering and fruiting stage, caducous (vs. more or less persistent) sepals ( Figs. 5L View FIGURE 5 , 6K View FIGURE 6 , 7I View FIGURE 7 , 11F View FIGURE 11 , 12G View FIGURE 12 ), more numerous (40‒60 vs. 15‒30) stamens ( Figs. 5L View FIGURE 5 , 6K View FIGURE 6 , 7I View FIGURE 7 , 11F View FIGURE 11 , 12G View FIGURE 12 ), and apically slightly recurved (vs. straight) styles ( Figs. 5O View FIGURE 5 , 6N View FIGURE 6 , 7K View FIGURE 7 , 11G View FIGURE 11 , 12J View FIGURE 12 ) (also see Table 1 View TABLE 1 ). Thalictrum fortunei has been recorded to occur in southern Anhui, southern Fujian, southern Henan, eastern Hubei, southern Jiangsu, northern Jiangxi and Zhejiang provinces, China ( Anonymous 1972, 1976, 1981, 1982, Wang & Wang 1979, Lin & Zhao 1985, Wang 1987, 2000, 2004, 2018, Lin 1992, Fu 2001, Fu & Zhu 2001, Deng & Ye 2013, Wang & Liu 2016, Xie 2016, Yuan et al. 2018, Zhang 2021), and T. fargesii has been recorded to occur in Chongqing, Gansu, Guizhou, Henan, Hubei, Shaanxi and Sichuan ( Anonymous 1976, 1981, 2014, Wang & Wang 1974, 1979, Wang 1980, 2018, Li 1986, Xie 2016), but actually the former occurs in southern Anhui, eastern Hubei, southern Jiangsu, northern Jiangxi and Zhejiang, very likely not in Fujian and Henan, whereas the latter occurs in Anhui, Chongqing, Gansu, Guizhou, Henan, Hubei, Hunan, Jiangxi, Shaanxi, Sichuan and Zhejiang. We have not as yet seen any specimens of T. fortunei from Fujian and Henan. Some specimens from Anhui, Jiangxi and Zhejiang have been correctly identified as T. fargesii or T. pallidum Franchet (1885: 187) (a synonym of T. fargesii ) ( Fig. 13 View FIGURE 13 ). Li et al. (2016) correctly cited some specimens from Jiangxi and Zhejiang under T. fargesii .
Thalictrum argyi had long been reduced to the synonymy of T. javanicum Blume (1825: 2) until it was placed in synonymy with T. fortunei by Yuan et al. (2018). We have checked the type material of T. argyi and here we accept that decision. Judging from the fact that T. argyi was described on the basis of material from Jiangsu, the treatment by Yuan et al. (2018) is also more justifiable. According to Zeng et al. (2021), T. javanicum is distributed only in Indonesia (Java), not in China.
