This species is similar to P.tentaculatus ( Lindl. ) J. J. Smith. The main difference is that the distance between the lips of this species is rod-shaped or spindle-shaped, 4-5 mm long, equal to or longer than the middle sepals, and the flowering period is 8-9 ( -10 ) months. The distance between the lips of the latter is spherical, 1-2.5mm long, much shorter than the sepals, and the flowering period is easy to identify from February to April.
Habenaria flagellifera recorded by Liu Tangrui and Su Hongjie in ' Taiwan Flora 5 : 1020.1978 ' may be misidentified as this species because its plant remains black after drying, the end of the distance is not 2 shallow, and the lateral lobe of the lip is filamentous.
The plant is 248 ( -80 ) cm tall. |

Plants slender, 17-48 cm tall. Tubers subglobose to oblong-ellipsoid, 0.8-2 × 0.5-1.5 cm. Stem with 2-4 tubular sheaths at base, 3-5-leaved. |

Leaves clustered near base to somewhat spaced along stem, elliptic-lanceolate, 2.5-12 × 0.6-3.5 cm, base attenuate, apex acute to obtuse. |

Inflorescence 13-38 cm; peduncle cylindric, slender; sterile bracts few, lanceolate, to 2 cm; rachis 6-23 cm, laxly to subdensely many flowered; floral bracts ovate-lanceolate, 6-11 mm, shorter than to slightly exceeding ovary, apex acuminate. Flowers erect, pale yellowish green; ovary 7-9 mm including pedicel. Dorsal sepal erect, oblong-ovate, concave, 2-3 × ca. 1.5 mm, 1-veined, apex obtuse; lateral sepals spreading, oblong, 3-3.5 × ca. 1.2 mm, slightly narrower than dorsal sepal, apex obtuse. Petals connivent with dorsal sepal and forming a hood, ovate-oblong, oblique, 3-3.5 × 1.5-2 mm, 1- or 2-veined, apex obtuse; lip narrowly oblong, 3-3.5 × ca. 0.5 mm, divided near base by a transverse ridge into a short, concave hypochile and a longer, deflexed, deeply 3-lobed epichile, ecallose; lateral lobes spreading at right angles to axis of lip, horizontal or ascending, filiform, 8-15 mm; mid-lobe narrowly oblong-lanceolate, 2-3 mm, apex obtuse; spur pendulous, fusiform, 3-5 mm, apex obtuse or sometimes shallowly 2-lobed. Column ca. 1 mm; viscidia ellipsoid. Fl. Jul-Oct. |
