    Thailand, Tak, Mae Sot distr., Wat Tham Inthanin, D. J. Middleton, C. Hemrat, P. Karaket, C. Puglisi & S. Suddee 5775 (holotype BKF; isotypes E, SING).
    Habit
    Herb to 50 cm tall.
    Stem
    Stems fleshy, dark red or green at base, otherwise pale green, glabrous or sparsely hairy.
    Leaves
    Leaves opposite, with the exception of the single basal leaf, fleshy (very thin when dry); petioles 0.2 - 1.5 cm long, glabrous; blades pale green above, paler be­neath, lanceolate, 3.75 - 14 x 2.6 - 8.5 cm, 1.3 - 1.7 times as long as wide, sparsely and minutely tomentose above and beneath, above with additional scattered eglandular hairs, base obtuse to cordate, apex acute to acuminate, margin entire to obscurely serrulate, 3 - 8 pairs of secondary veins in the opposite leaves, 7 - 13 in the basal leaf, venation raised beneath in fresh material, tertiary venation almost invisible.
    Inflorescences
    Inflorescence epiphyllous, 1 - 8-flowered, forming a crest where the young flowers develop flush to the midrib and then progressively curve upwards and backwards towards the stem; peduncles fused with the petiole; pedicels green, 0.5 - 1.3 cm long, sparsely hairy.
    Calyx
    Calyx green, actinomorphic, tube 0.2 - 0.5 mm long, lobes lanceolate, 3 - 9 x 0.5 - 1 mm, inconsistently with some serration towards the apex, apex acute, outside sparsely eglandular hairy at base, hairier distally, inside with an indumentum of sparse sessile glands.
    Corolla
    Corolla 1 - 1.5 cm long, tube with a narrow basal portion, greenish white, 5 - 6 mm long, c. 1 mm diam., curved downwards, glabrous, then broadening into a funnel-shaped distal portion, white, pubescent outside, inside glabrous, with a yellowstripe ventrally, lobes pale lilac, the upper densely covered in stalked glands, the lower central lobe sparsely so, the lower lateral lobes glabrous; tube length 0.9 – 1.2 cm dorsally, 1 - 1.1 cm ventrally, 0.85 - 0.9 cm laterally between lips, upper lobes broadly elliptic, 2.5 - 3 x4 - 4.7mm, lower lateral lobes elliptic, 2 – 4 x 4 – 5 mm, lower central lobe rounded, 3 – 4 x 4- 5mm.Stamens arising 4 - 6.5 mm above the corolla tube base, filaments glabrous, 3 - 3.5 mm long, straight, anthers with a dense indumentum of long hairs dorsally, c. 1 x 0.7 - 0.8 mm, apically joined by a connective, thecae divergent; lateral staminodes c. 2 mm long, arising 3 - 5 mm above the tube base, central staminode c. 1 mm long, arising c. 4 mm above tube base.
    Disc
    Disk absent.
    Pistil
    Pistil 0.8 - 1.2 cm long; ovary fusiform, 3 - 5 mm long, papillose, with pubescence restricted to the apex; style 5 - 6mmlong, apically curved, hairy; stigma with lobes c. 0.5 mm long, c. 0.8 mm wide, narrowly elliptic, glabrous.
    Fruits
    Fruit green, 2 - 6 cm long, 0.9 - 1.1 mm diam., glabrous at base, sparsely hairy distally, straight or curved.
    Seeds
    Seeds light brown with reddish apices, elliptic, 0.5 - 0.6 x 0.2 - 0.3 mm.
    Distribution
    Thailand: Tak
    Ecology
    Lithophyte on limestone in mixed deciduous forest.
    Conservation
    Endangered [EN B1ab(iii,iv)+B2ab(iii,iv)]. The known EOO of this species would qualify it for Critically Endangered but the collecting localities are in a limestone range much of which has so far not been explored and where it is also likely to occur. Even if it were to occur throughout this range its EOO would still qualify it as Endangered. Parts of this range, including some of the known localities, are outside protected areas and subject to disturbance from visitors, particularly at the religious sites.
    Note
    The species is named in honour of Chandee Hemrat, one of the collectors of the types of all of the new species. See notes under Microchirita lilacina. Similar to Microchirita suddeei D. J. Middleton & Triboun (2013:18),M. lilacina and M. albiflora Middleton & Triboun (2013: 19), but is characterised by the combination of open corolla mouth (unlike M. suddeei and M. albiflora), ventral yellow stripe (unlike M. suddeei) and hairy anthers (unlike M. albiflora and M. lilacina).
