Pterostylis cycnocephala Fitzg.

Plant small, c. 2–10 cm. tall at fl. Stem ± hidden by lfy bracts. Rosette lvs ∞, c. 5–15 × 5–12 mm.; lamina ovate, not clearly distinct from broadly winged petiole, firm-textured, bluish green; cauline lvs smaller, sheathing. Fls (1)–2–7, each with a sheathing floral bract; per. bluish green with pale stripes. Dorsal sepal 5–10 mm. tall, broad, apiculate; lateral sepals little shorter, almost completely connate into a flat lamina bidentate at tip, strongly deflexed in fully open fl. Petals just shorter than dorsal sepal, the anterior margin quite smooth. Labellum short, broad, obtuse, produced backwards into a smoothly rounded appendage from which a thick median knob juts forward. Column short, broad; wings broader than long, ciliate over most of their free margins; stigma oblong.

Widespread and common, mainly occurring in drier inland areas extending onto plains, growing in open forest, woodland and grassland in shallow well-drained clay loam and sandy loam; generally rare in coastal and near-coastal sites.
