Morphology General Habit
Erect or ascending annual or short lived perennial herb, up to 30 cm tall, rootstock woody
Morphology Leaves
Leaves often purple beneath, membranous, usually in 3 - 4 (5) basal pairs, rarely separated by long internodes, if so the middle pairs of leaves always largest, upper pair sessile or subsessile, lower pairs distinctly petiolate, ovate, 30 - 130 x 35 - 80 mm, apex acute or obtuse, base truncate or cordate, margin serrate, sometimes crenate, sparsely hirsute above, glabrescent or sparsely hirsute with hairs denser on veins beneath; petioles slender, up to 85 mm long in lower pair, hirsute
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens far exserted, twice or more as long as anterior corolla lip, anterior slightly longer
Morphology Reproductive morphology Flowers Calyx
Calyx 3 - 4 mm long at anthesis, 8 - 9 mm long in fruit; posterior lip obovate, apiculate at apex, decurrent on tube, glabrous both sides or with short hairs on nerves inside, margin sometimes ciliate; anterior lip with teeth subulate, median teeth longest, lateral teeth shorter than posterior; tube hirsute outside, glabrous inside
Morphology Reproductive morphology Flowers Corolla
Corolla bluish-purple, 15 - 25 mm long; posterior lip 3-lobed, midlobe emarginate; anterior lip entire, oblong, concave, ± equal in length to the posterior; tube slender 14 - 15 mm long, pubescent outside
Morphology Reproductive morphology Flowers Disc

Morphology Reproductive morphology Flowers Gynoecium Style
Style long exserted, far exceeding stamens, clavate and shortly bifid at apex
Morphology Reproductive morphology Fruits
Nutlets brown, oblong or ellipsoid, 1.5 - 2 mm long, minutely reticulate, producing mucilage when wet.
Morphology Reproductive morphology Inflorescences
Inflorescence terminal, up to 30 cm long; axis hirsute; bracts sessile, subtending 3 flowers, forming a small apical coma, persistent, ovate, 2 - 7 mm long, longer than pedicel in flower, shorter or longer in fruit, acuminate, cuspidate, ciliate, adaxial glabrous, abaxial hirsute; pedicels 1.5 - 2 mm long at anthesis, 3 - 4 mm long in fruit, hirsute
Morphology Stem
Stems round- quadrandular, puberulous, sometimes branched
This species is easily recognised by the hirsute indumentum, and by the leaves that are usually subradical, cordate and purple beneath, if the leaves are separated by long internodes, the middle pairs of leaves are always the largest. The species often occurs in shady ground in bamboo forest. The following syntypes held in CAL have not been seen for this study: Burma, Maymyo Hill, 3 March 1909, Dr King's collector 32 (syntype CAL, photograph of type KYO!); Burma, Tenasserim, Parish s.n. (syntype CAL); Burma, Meiktila, Prazer s.n. (syntype CAL). The only syntype available at K is chosen as the lectotype.
Flowering and fruiting May - November.
Burma, Shan Hills, Terai, 600 m, June 1888, Collett 824 (K!, lectotype).
