Accepted Name : This is currently accepted.

Description : Plant up to 53 cm tall. Stems cane-like, erect-spreading, indeterminate in growth, leafy, up to 42 cm long and 2.7 cm in diameter. Leaves 11–19, distichous, ligulate, unequally bilobed at apex, 6–23.5 by 1.9–2.7 cm; sheaths clasping, 3–5.3 cm long. Inflorescences erect, axillary from upper leaf sheaths, 1- or 2-flowered; peduncle covered by sheaths, cymbiform above; rachis up to 4.4 cm long. Flowers 8–8.5 cm across, sepals and petals pale rose-pink with darker margins; labellum white with an orange-yellow disk and purple spots around the margins; pedicel and ovary 28–38 mm long. Dorsal sepal oblong-oblanceolate, acute, mucronate, 71–72 by 24–27 mm; lateral sepals obliquely oblong, acute, mucronate, 64–65 by 21–23 mm, abaxially costate. Petals obliquely oblanceolate, acute, 66–67 by 21–24 mm. Labellum 3-lobed, fused to column for 4 mm, 66–67 by 21–24 mm; side lobes erect, subtriangular, obtuse, minutely hairy adaxially; mid-lobe porrect, ovate-triangular, acute, undulate, 18–19 by 21 mm; ornaments of 2 parallel ridges confluent and triangular in front, papillose.

Thailand : NORTHERN: province undisclosed (type: sine coll., cult. Wada s.n., holotype -TNS).

Distribution : Vietnam.

Ecology : No data available on habitat or altitudinal range. Flowering: recorded in March and April in cultivation.

Notes: The type specimen was prepared from a cultivated plant said to have originated in northern Thailand. Some skepticism is necessary because this region has been well-collected for species of horticultural interest over many decades. A great many novelties have been exported from Vietnam in the past two decades and this species has appeared in European nurseries and collections with a provenance of Vietnam, rather than Thailand.
