Basionym: Phreatia angraecoides

Epiphytic, erect, or ascending, several-stemmed; roots filiform, elongated, flexuose glabrous. Stems unbranched, erect or ascending, rooting at the base, elongated, up to 20 cm long, entirely covered with tightly clasping leaf-sheaths. Leaves erect-patent, linear-falcate, acuminate, glabrous, equitant, rather thick-textured, 2-2.8 cm long, up to 0.4 [‘4’] cm wide. Inflorescence axillary, cylindrical, densely many-flowered, up to 4 cm long, 0.4 cm diam. [across the flowers], surpassing the leaves; peduncle short, with several acuminate, glabrous, scales. Floral bracts lanceolate, acuminate, almost as long as the shortly pedicellate, ovary. Flowers subpatent. Median sepal lanceolate-oblong, obtuse, almost 0.1 cm long. Lateral sepals oblique ovate, acuminate, glabrous, as long as the median sepal. Petals patent obliquely lanceolate, acuminate, a little shorter than the sepals. Lip narrowly oblong-ligulate obtuse, almost as long as the petals. Column short, foot very short; clinandrium very low; rostellum notched in front. Anther rhomboid, rostrate-acuminate, in front slightly notched; pollinia 8, obliquely clavate; stipe linear, somewhat narrowed towards the viscidium, a little longer than the pollinia. Ovary shortly pedicellate, , clavate, glabrous, almost 0.2 cm long. (After Schlechter, 1905)
