Plant c. 5–20–(30) cm. tall. Stem internodes = or much > bracts. Rosette lvs ∞, lamina c. 1.5–3 × 1–2 cm., oblong-ovate, acute to subacute, petiole well-defined, narrowly winged; cauline lvs few, sheathing, bract-like. Fl. us. solitary, remote from highest bract only in tallest plants; top of stem and ovary strongly arched so that fl. faces downwards or even inwards towards stem. Dorsal sepal c. 2.5 cm. tall, rounded, apex acute; lateral sepals very shortly connate, diverging at narrow angle, tips acuminate and hardly overtopping galea, surface minutely rough. Petals ± = dorsal sepal, acute. Labellum narrow-triangular, strongly arched, protruding, apex subacute, its slightly incurved margins ± bristly with short stiff hairs. Column much shorter than labellum; stigma elliptic, rather prominent in N.Z. specimens.
