Anotis ingrata Wallich ex J. D. Hooker, Fl. Brit. India 3: 71. 1880.

Herbs, perennial, erect to procumbent, to 1 m tall; stems terete to flattened or ridged, often sulcate, glabrous or sometimes sparsely hirtellous to puberulent near nodes. Leaves sessile or petiolate; petiole to 12 mm; blade drying papery, lanceolate, elliptic, ovate-lanceolate, or rarely ovate, 4-11.5 × 1-4 cm, adaxially glabrous or sparsely to moderately strigillose, pilosulous, pilose, or hispid, abaxially glabrous except usually densely puberulent, hirtellous, or pilosulous on principal veins, base obtuse to acute, apex acute to acuminate; secondary veins 4-9 pairs; stipules rounded to broadly triangular, 1-2.5 mm, puberulent, hirtellous, or glabrescent, with 3 to numerous setae or linear lobes 3-15 mm, glabrous to ciliolate, often inserted below top of sheath. Inflorescences terminal, subterminal, or pseudoaxillary, cymose, lax, dichasial with axes often asymmetrical, branched to 2-4 orders, glabrous; peduncle 1-4.5 cm; bracts stipuliform to reduced and erose or ciliate, 0.2-1.5 mm; pedicels to 0.5 mm. Calyx glabrous; hypanthium portion obconic, 0.8-1 mm; limb divided to base; lobes narrowly triangular, linear, or narrowly ligulate, 1.2-2 mm, entire to ciliolate. Corolla white, funnelform, outside glabrous; tube 4-6 mm, apparently pubescent inside; lobes narrowly triangular to ligulate, 2.5-3 mm, often puberulent adaxially. Capsule compressed globose, ca. 2 × 3 mm, slightly dicoccous, glabrous, with calyx lobes often elongating, to 4 mm, with pedicels sometimes elongating, to 2 mm. Fl. Jun-Sep, fr. Jul.

Grassy slopes on riverbanks, forests on mountain slopes; 500-1500 m. Fujian, Guizhou, Hubei, Hunan, Jiangsu, Sichuan, Xizang, Yunnan, Zhejiang [Bhutan, India, Nepal].

Several specimens from Sichuan have been suggested (in herb.) to belong to Neanotis urophylla (Wallich ex Wight & Arnott) W. H. Lewis (Ann. Missouri Bot. Gard. 53: 40. 1966; Hedyotis urophylla Wallich ex Wight & Arnott, Prodr. Fl. Ind. Orient. 404. 1834), but they are provisionally included here pending further study, including clarification of the identity of N. urophylla (W. P. Fang 2148, 2182, 3061, all P!).

The identity of the name Neanotis mairei (H. Léveillé) Lauener & D. K. Ferguson (Notes Roy. Bot. Gard. Edinburgh 32: 110. 1972; Ophiorrhiza mairei H. Léveillé, Repert. Spec. Nov. Regni Veg. 13: 177. 1914, from Yunnan) is not entirely clear. This name was found to belong to Neanotis after Lewis’s work and was said by Lauener to be similar to N. urophylla and N. ingrata. The characters used by Lauener to distinguish N. mairei from N. ingrata fall within the circumscription of N. ingrata here, so this name is probably a synonym; however, until authentic material is seen this cannot be conclusively synonymized.
