Chiloglottis cornuta Hook.F.

Plant at fl. c. 4–10 cm. tall, at fr. to 30 cm. tall, the mature capsule us. far above the floral bract. Stem erect, slightly fleshy, glab. Green lvs 2, us. close together, c. 3–10 × 1–3 cm., linear-oblong to oblong-lanceolate, acute to subacute, petiolate, glab. and ± fleshy. Floral bract with long cylindric sheath, lamina = or > ovary, green, sts larger and appearing as third lf. Fl. erect, between or above spreading lvs. Per. c. 1.5 cm. tall, green, glab., ± fleshy. Sepals shortly caudate; dorsal ovate-lanceolate; lateral much narrower, ± channelled. Petals slightly shorter, ovate-lanceolate, erect to spreading. Labellum broadly to narrowly triangular, on short claw; margins entire; calli dark green to reddish, ± globose, variously arranged in a ± central group, 2 often forming thickened inturned auricles near the base. Column almost as long as lip, the foot ending in a transverse thickening; wing narrow to level of stigma, there wider and extending almost to top of anther in broad, us. incurved lobe.

Widespread and often locally common, extending from the coast in some areas (King Island.) to high in the mountains. Found growing among shrubs, ferns, moss colonies and deep forest litter in shady, humid, sheltered sites in tall, moist to wet forest, including wet sclerophyll forest dominated by mountain ash, rainforest dominated by myrtle beech, streamside vegetation, fern gullies and coastal scrub in freely draining to moisture-retentive loam; plants occasionally grow in shallow running water. It also colonises litter on boulders, rotting logs, living and dead tree fern trunks and sphagnum mounds in subalpine areas. In S.A. it grows in bogs with sphagnum and ferns.
