Muelleria 8: 78 (1993) APNI
Threat status:EPBC: vulnerable (VU); Victoria: vulnerable (v); listed in Flora and Fauna Guarantee Act 1988
Flowering plant to 20–45 cm tall, stem leaves 5–9, spreading, linear-lanceolate, 2–6 cm long, 3–6 mm wide, dark green. Rosette leaves on a separate plant, 3–6, narrowly ovate to lanceolate, 10–25 mm long, 3–5 mm wide. Flowers 1–7, 1.5–1.8 cm long, shiny, translucent green with dark green stripes; dorsal sepal with short apical point; lateral sepals deflexed, conjoined part oblong, 13–16 mm long, 6–7 mm wide; petals slightly falcate, with a well-developed basal flange. Labellum narrowly oblong, 6–7 mm long, 2.5–3 mm wide, emerald green with a dark green, truncate basal mound and central stripe, covered with numerous, short, transparent, bead-like cells, longer and hair-like at base, apex attenuate, notched. Flowers Jul.–Sep.

Distinguished from Pterostylis smaragdyna by its smaller, paler flowers and a smaller labellum with less developed lateral lobes. Some plants of intermediate size can be difficult to assign to either P. chlorogramma or P. smaragdyna.
