It usually grows on rocks, rarely as an epiphyte, and has thin, spreading leaves and spikes of up to fifteen, usually pink flowers in late winter to spring.

Spongy, white roots enable it to absorb water quickly from a wet rock surface whilst at other times, reflect light to avoid overheating during long dry spells.

The leaves are thin, green and smooth, folded along the mid-line, narrow egg-shaped and 3–10 cm (1–4 in) long and 10–20 mm (0.39–0.79 in) wide.

[2][10] The specific epithet (kingianum) honours Admiral Phillip Parker King, RN, an early explorer of Australia’s southern and western coast.

It is available from specialist orchid nurseries but, like many Australian native plants, it is illegal to collect specimens growing in the wild.
