1. Scaphochlamys anomala (Hallier f.) Searle (2010: 85) . Kaempferia anomala Hallier (1898: 357) . ≡ Gastrochilus anomalum (Hallier f.) Schuman (1904: 92) . ≡ Boesenbergia anomala (Hallier f.) Schlechter (1913: 315) ≡ Gastrochilus hallieri Ridley (1899: 109 , nom. illegit. Type:— INDONESIA. Cultivated in Bogor Botanic Gardens, originally from

Borneo (Kalimantan), J.G. Hallier s.n. (holo BO† ( Valeton 1918)); Neotype (designated as ‘lectotype’ by Searle, 2010: 86):—Figure drawn from J.G. Hallier s.n., cult. Bogor, originally from Borneo (Kalimantan), published as t. IX, Fig. 3 , Hallier (1898: 357)).

Terrestrial, perennial, rhizomatous herbs, to c. 20 cm tall. Rhizome creeping, with short internodes, glossy green when young turning bone white with age; roots thread-like, non-tuberous, white and slightly branched. Elements short, congested, 1- to 2-foliates; petiole 7 cm long, slender, semi-smooth, canaliculate, green, sub-opaque, lined with pale parallel veins; outer leafless sheath short, c. 1 cm long, oval, apex acute, scarious (thin, dry and membranous); inner leafless sheath long, 3 cm long, cylindrical, apex acute, completely green, veins visible as pale parallel lines, opaque, margin pale and membranous; older sheaths paler, becoming scarious, parallel-veined; lamina up to 11 × 5 cm, symmetric, ovate to lanceolate, apex acute, recurved, base rounded, adaxial surface uniform glossy grass-green, 8 secondary veins, abaxial surface finely pubescent, concentrated towards the midrib, paler, glaucous–green, thickly covered in minute blue-green spots. Inflorescence terminal, sessile within the sheaths, highly reduced with only 3 bracts; bract 1.7 cm long, apex acute; flower small; floral tube slender, 15 × 1 mm, emerging 6 mm above the sheath, white; corolla lobes 3, each 7 × 2–3 mm at the base, lanceolate, hooded, white, semi- transparent with 3 dark parallel veins inside; lateral staminodes 2, about half the size of the corolla lobes, 4 × just over 1 mm, petaloid and small, lanceolate, curved, papillose, apex acute, green and lined with 3 transparent veins; labellum slightly above the corolla lobes, deeply cleft, claw 4 × 3 mm, lobes c. 4 mm long and just as wide, somewhat cuneate with broadly obovate, white with a yellow median band; stamen with very short filament, anther obovate and erect, thecae yellow, 3 × 1 mm, the margins wrapped around the style apex, crest truncate; stigma white, ostiole containing erect cilia. Fruit and seeds unknown.

Distribution and ecology: — Borneo, Kalimantan Barat, Sintang Regency, ‘in the jungle at the base of Mt Liang Gagang’ (modern Bukit Liangkungkam 00.049010S, 113.119000E), no more detailed ecology recorded although likely on Permo-Triassic metamorphics ( Tate 2001).

Conservation status:— Scaphochlamys anomala is Not Evaluated (NE; IUCN 2012) as it is has not yet been evaluated against the criteria.

Discussion:—The lectotype depicts a lax inflorescence with the first bracteole longer than the associated bract. The white labellum with veins (fide Searle 2010) is highly similar to other species in this group. However, the inflorescence is terminal and enclosed by sheaths, not borne on a peduncle near the leaf base as in all the other species in this group.
