全島中高海拔山區,林緣、路邊或開闊地。

1. Anemone vitifolia Buch.-Ham. ex DC., Syst. 1: 210. 1818. 小白頭翁(野棉花) Pl.236

Perennial erect pubescent herbs, 30-120 cm tall. Leaves ternate, radical (6.0-)6.3-11.6(-14.3) cm long, (4.6-)4.7-7.9(-8.6) cm wide, elliptic or ovate, apex acute, base obtuse, truncate or acute; lateral leaves oblique, ternately divided or unlobed; puberulous on adaxial surface, tomentose on abaxial ?surface; petioles 5.5-36.0 cm long. Inflorescence a compound dichasium; pedicels 6.5-17.8 cm long; bracts 2 or 3, opposite or whorled, ternately divided or sometimes palmate, pubescent on both sides; petiolate. Flowers 25-38 mm in diam., white. Sepals 5 or more, unequal, 10-20 mm long, 10-18 mm wide, ovate, broadly elliptic or obovate; apex acute or retuse; imbricate; glabrous on adaxial side, pubescent on abaxial side. Stamens numerous, anthers 2-8 mm long, elliptic-globose; filaments linear. Carpels numerous; styles pilose. Achenes 2.5-3.5 mm long, ovate-globose, many, pilose; subsessile; aggregate in a globose head Northern Myanmar (Burma), Bhutan, Nepal, northern India, Sikkim, mainland China and Taiwan. In Taiwan widely distributed in open places between 800 and 3,200 m.

This taxon is very similar to A. hupehensis Lem. And A. tomentosa (Maxim.) Pei, differing only in hair pattern on the abaxial leaf surface (densely velutinous and tomentose) and flower color (white, pale pink and pink). However, such characters are variable and overlap on the same individual. We have not seen many specimens from the mainland so we will continue to recognize A. vitifolia even though the Taiwanese plants have been treated as A. hupehensis f. alba (Wang, 1974, 1980). This complex needs further investigation.
