Ying; H. lindleyana var. glabricalycina (Honda) H. Hara; Neanotis hirsuta (Linnaeus f.) W. H. Lewis var. glabricalycina (Honda) W. H. Lewis; Oldenlandia hirsuta Linnaeus f. var. glabricalycina Honda.
Herbs, perhaps perennial, procumbent or ascending in upper parts; stems subterete to angled or compressed, smooth to ridged and/or sulcate, glabrous. Leaves subsessile or petiolate; petiole to 10 mm, glabrous; blade elliptic, lanceolate, or ovate, 1-5 × 0.5-2 cm, glabrous or sparsely strigillose or scaberulous adaxially at least near margins, abaxially glabrous or sometimes puberulent on principal veins, base acute to obtuse, apex acuminate to acute; secondary veins 3-9 pairs; stipules sheath rounded to broadly triangular, 0.8-1.5 mm, glabrous to puberulent, with 2-7 bristles or linear lobes 0.3-3 mm, glabrous, often glandular. Inflorescences terminal and/or pseudoaxillary at upper nodes on principal and short axillary stems, capitate to congested-cymose, 1 to usually several flowered, glabrous, sessile or peduncle to 3 mm; bracts reduced, stipuliform, to 0.5 mm; pedicels to 2 mm. Flowers subsessile to pedicellate. Calyx glabrous; hypanthium portion cupuliform to turbinate, 0.8-1.2 mm; limb lobed to base; lobes triangular or ligulate, 1.5-2.5 mm. Corolla white, shortly tubular to rotate, outside glabrous or puberulent; tube 1-1.5 mm, apparently glabrous in throat; lobes narrowly triangular-oblong to ligulate, 1.5-2 mm. Capsule compressed subglobose to obovoid, ca. 3 × 4 mm, slightly dicoccous, glabrous, smooth. Fl. and fr. Jul-Oct.
Forests on gentle slopes or at streamsides; 200-800 m. Guangdong, Guangxi, Jiangxi, Sichuan, Taiwan [Japan, Thailand].
This name is applied here more broadly than by previous authors; many of the plants that now belong to this species were formerly included in a more broadly circumscribed Neanotis hirsuta. The varieties of N. hirsuta recognized by W. C. Ko (in FRPS 71(1): 84-85. 1999) are not completely distinct from each other and belong to N. kwangtungensis as circumscribed here. The name Hedyotis lindleyana as used for specimens from Japan appears to be a synonym of N. kwangtungensis rather than of N. hirsuta, and the range of this species is here extended to include Japan; N. kwangtungensis as treated here is apparently equivalent to "N. hirsuta" of the Fl. Japan (3a: 218-219. 1993). The name "Hedyotis kwangtungensis (Merrill & Metcalf) Ko" is annotated on some specimens but does not appear to have been published.This name is applied here more broadly than by previous authors; many of the plants that now belong to this species were formerly included in a more broadly circumscribed Neanotis hirsuta.
