Leaves erect, linear, long acuminate, at the base narrowed into a 1-1.5 cm long petiole, glabrous, coriaceous, including the petiole 8-11 cm long, near the middle 2-3.5 cm long. Inflorescences few, arranged into a terminal capitulum, covered with lanceolate, acuminate scales. Floral bracts very small, ovate, apiculate, hyaline. Flowers glabrous except for the ovary. Sepals oblong, narrowly obtuse, glabrous, about 0.7 cm long. Lateral sepals oblique, at the base dilated and connate along the front margin; mentum oblong, obtuse, 0.25 cm long. Petals oblique, narrowly lanceolate, acuminate, glabrous, a little shorter than the sepals. Lip oblanceolate-ligulate, in apical third carnose-thickened, obtuse, 0.9 cm long, in the middle with an almost round depression, with two thin, parallel raised basal lines or lamellae, decurrent in the middle. Column less than half as long as the lip, glabrous, arms obliquely oblong; foot medium-sized. Anther galeate-cucullate, minutely apiculate, glabrous.
