Inflorescence +80–100 cm +tall, dark brownish purple, +3–6 mm +in diameter, bearing 20–30 scale-like leaves. Rhizome condensed, producing, numerous, horizontally or downwardly elongate roots. Rachis +10–20 cm +, glabrous to subglabrous, with c. 30 flowers; floral bracts (linear-)lanceolate, acute, 15–25 × +1–3 mm +. Pedicel and ovary slightly tilted upwards or downwards, +24–32 mm +long, +2 mm +, pubescent. Flowers opening widely. Dorsal sepal ivory, often with purple veins, cymbiform, narrowly ovate to lanceolate, entirely pubescent on the dorsal side, margin entire, 17.0–18.0 × +4.7–4.9 mm +, acute at the apex; lateral sepal ivory, narrowly ovate to lanceolate, entirely pubescent on the dorsal side, margin entire or minutely denticulate, 17.0–18.0 × +4.2–4.4 mm +, slightly outwardly curved and acute at the apex.

Labellum ivory white, often with maroon marking; hypochile trapezoid, +4.1–4.2 mm +× c. +2.5 mm +wide, with well developed, erect, obliquely triangular, obtuse to acute side lobes, 2.3–2.5 × +3.8–4.2 mm +when flattened; epichile +10.7–11.2 mm +× +6.2–6.4 mm +when flattened, trilobed, sidelobes c. 4 × +2 mm +, rounded, midlobe narrowly triangular +10.7–11.2 mm +× +2.2–2.4 mm +, thickened, erose at the apex.

In addition, only one individual of + +A. maliauensis + +was observed in the Imbak Canyon Conservation Area, +Sabah +, under a lowland dipterocarp forest. + +Aphyllorchis maliauensis + +flowers in mid-August in both populations. Furthermore, it is likely that + +A. maliauensis + +is distributed more widely because it seems to have sometimes been misidentified as the more widespread species, + +A. montana + +, which has similar gross morphology. For example, the + +Aphyllorchis +sp. + +recorded as + +A. montana + +by + +Beaman +et al. +(2001 + +; +Sarawak +, Borneo) and +Wood (2003 +; +Sabah +, Borneo) appears identical to + +A. maliauensis + +, judging from their photographs. + + +However, the original descriptions and subsequent literature clearly indicate that there is little morphological variation in + +A. montana sensu +Reichenbach (1876) + +, despite its extensive distribution, which includes +Sri Lanka +, +Assam +, southern +India +, the +Philippines +, Borneo, +Thailand +, +Taiwan +, +Japan +and +Indonesia +( +Reichenbach 1886 +, +Hooker 1890 +, +Schlechter 1906 +, +Ames 1908 +, +Hayata 1911 +, +Downie 1925 +, +Fukuyama 1934 +, + +Roy +et al. +2009 + +, + +Aravindhan +et al. +2013 + +, +Rao & Kumar 2015 +, +Fig. 4 +). Because the morphological differences between + +A. maliauensis + +and + +A. montana + +are clear and stable, + +A. maliauensis + +should be treated as an independent species rather than as an infraspecific taxon of + +A. montana +. + +Conducting additional surveys for + +A. maliauensis + +during the flowering season would reveal its precise distribution. + + + + \ No newline at end of file
