    Type
    Thailand, Uthai Thani, Lan Sak, Huppatat Non Hunting Area, D. J. Middleton, C. Hemrat, P. Karaket, C. Puglisi & S. Suddee 5688 (holotype BKF; isotypes AAU, E, K, QBG, SING),
    Habit
    Herb to 35 cm tall, Stems fleshy, pale green, glabrous or sparsely hairy, Leaves opposite, with the exception of the single basal leaf, fleshy (very thin when dry); petioles 0.1 - 0.5 cm long, sparsely hairy; blades pale green above, pale grey-green beneath, lanceolate, 3.4 – 40 x 1.7 - 29 cm, 1.3 - 2.2 times as long as wide, minutely tomentose above and beneath, base usually rounded-obtuse, sometimes slightly cordate or slightly decurrent, apex acuminate to acute, margin entire, 6 - 11 pairs of secondary veins in the opposite leaves, 8 - 14 pairs in the basal leaf, venation raised beneath in fresh material, tertiary venation barely visible and loosely reticulate.
    Inflorescences
    Inflorescence epiphyllous, many-flowered (10 to more than 20 flowers), 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 pale green, 0.5 - 1.3 cm long, pubescent.
    Calyx
    Calyx green, slightly bilabiate, tube 0.4 - 0.7 mm long, lobes lanceolate, 4 - 7x 0.4 - 0.6 mm, membranous along the side edges, apex more or less narrowly obtuse, outside eglandular hairy through­out, inside only towards the apex.
    Corolla
    Corolla 0.7- 1cmlong, tube greenish white, narrow, glabrous at base, mouth personate due to the raised ventral lip, limb densely pubescent outside, upper lip pale green, strongly reflexed upwards, densely papillose, lower lip white with a densely papillose yellow marking at base; tube length 0.4 - 0.8 cm dorsally, 0.6 - 0.9 cm ventrally, 0.4 - 0.7 cm laterally between lips, upper lobes small and elliptic, 0.7 - 0.8 x 1 - 1.3 mm, lower lateral lobes elliptic, 1.5 - 1.8 x 2.2 - 2.3 mm, lower central lobe elliptic, 1.2 - 1.3 x 1.8 - 3 mm.
    Stamens
    Stamens arising 2.7 - 3.7 mm above the corolla tube base, filaments pale green, glabrous, 0.5 - 1.2 mm long, anthers glabrous, 1.1 - 1.7x 0.3 - 0.5 mm, apically joined by a connective, thecae slightly divergent, anthers and connective white; lateral staminodes absent or to 0.2 mm long, arising c. 1.7 mm above the tube base, central staminode extremely reduced or absent.
    Disc
    Disk aventral lobe, 0.6 - 1 mm high.Pistil 2.2 - 2.3 mm long; ovary urceolate, c. 1.5 mm, glabrous or sparsely glandular at base, apically eglandular hairy; style c. 0.6 mm, hairy; stigma broadly bilobed, lobes 0.1 - 0.2 mm long, rounded.
    Fruits
    Fruit green, 1 - 3 cm long, 1 - 2 mm diam., hairy almost exclusively in the terminal half, straight or curved.
    Seeds
    Seeds pale brown, elliptic, 0.4- 0.5 x 0.2- 0.3mm.
    Distribution
    Thailand: Uthai Thani. Only known from the type collection
    Ecology
    Lithophyte, on bank over limestone rocks in secondary forest.
    Conservation
    Critically Endangered [CR B1ab(iii,iv)+B2ab(iii,iv)]. This species is only known from the type collection in the Huppatat Non Hunting Area, where only one, small population was observed. The limestone range there is only about 12 km2 in total and is subject to disturbance from tourism. There are no collections from the nearby Khao Pha Ra, and the area is surrounded by cultivated land.
    Note
    Named for the personate corolla mouth. Microchirita personata is the most immediately recognisable of the four new species and arguably the most distinctive species in the genus. Its main diagnostic feature is the personate corolla, a unique occurrence in Microchirita. The small corolla is also remarkable, with the entire flower hardly reaching 1 cm in length and the upper two lobes strongly reduced. M. personata appears most similar to M. woodii D. J. Middleton & Triboun (2013: 15) and M. huppatatensis, both with a corolla primarily white and with a smaller upper lip and expanded and slightly raised lower lip. These species, however, have much larger and non-personate flowers. Differs from all other species of Microchirita in the personate corolla and the reduced upper corolla lobes.
