4. Neanotis hirsuta (Linnaeus f.) W. H. Lewis, Ann. Missouri Bot. Gard. 53: 38. 1966.

薄叶新耳草 bao ye xin er cao

Oldenlandia hirsuta Linnaeus f., Suppl. Pl. 127. 1782; Anotis hirsuta (Linnaeus f.) Boerlage; Hedyotis hirsuta (Linnaeus f.) Smith (1811), not Lamarck (1789); H. stipulata R. Brown ex J. D. Hooker, nom. illeg. superfl.; O. japonica Miquel.

Herbs, perennial, lower stems decumbent and upper stems apparently ascending; stems terete to 4-angled, glabrous to hirtellous in lines or throughout, angles sometimes thickened. Leaves petiolate; petiole 1-5 mm, glabrous to hirtellous or hispid; blade drying papery, ovate, lanceolate, or elliptic, 1-5.5 × 0.5-2 cm, adaxially glabrous or sparsely to moderately strigillose, scaberulous, or hirtellous, abaxially densely hirtellous or glabrous except sparsely strigillose or puberulent on principal veins, base rounded to cuneate, apex acute; secondary veins 3-5 pairs; stipules rounded to triangular, 1-2 mm, glabrous to hirtellous, laciniate to setose, lobes or bristles 3-7, 0.5-5 mm, glabrous to ciliate. Inflorescences terminal and/or pseudoaxillary, laxly cymose, branched to 2 or 3 orders often asymmetrically, with flowers borne separately or in glomerules of 2-5, glabrous or hirtellous; peduncle 0.8-3 cm; bracts laciniate or stipuliform, 0.5-2 mm. Flowers sessile or subsessile, floral biology unknown. Calyx glabrous to densely hirtellous; hypanthium portion obconic, ca. 1 mm; limb divided essentially to base; lobes linear-lanceolate, 1-2 mm. Corolla white, funnelform, outside glabrous; tube 3.5-4 mm, puberulent or perhaps pubescent inside; lobes ovate to triangular, 2.2-3 mm. Capsule compressed globose, 2-2.5 × 2.5-3 mm, glabrous to hirtellous. Fl. and fr. Jun-Oct.

Wet sites at streamsides or in forests; 500-1000(-1500) m. Guangdong, Hainan, Jiangsu, Jiangxi, Taiwan, Yunnan, Zhejiang [?Bhutan, Cambodia, India, Japan, Korea, Laos, Myanmar, Nepal, Pakistan, Thailand, Vietnam].

The application of this name is problematic, and it seems to have been used in the literature and the herbarium for different species in different regions (e.g., cf. Fl. Bhutan 2(2): 768. 1999; Fl. Japan 3a: 218-219. 1993). The confusion probably started with Hooker’s circumscription of this species (Fl. Brit. India 3: 63. 1880), which included three other names in synonymy to circumscribe morphologically highly varied group of plants from India through Java and Japan. Here Neanotis hirsuta is circumscribed more narrowly. The varieties of N. hirsuta recognized by W. C. Ko (in FRPS 71(1): 84-85. 1999) are not completely distinct morphologically and fall within N. kwangtungensis as circumscribed here.
