Plant: Terrestrial tuberous herb. 1 to 4cm high when in flower. Many plants do not bear flowers. Leaves on a long stalk. Kidney-shaped to orbicular. Extremely variable in both size and shape.

Flowers: Solitary. Flower above or below the leaf. 1 - 1.5cm high. Lateral sepals very long, Petals much shorter. Labellum varies in colour from transparent green through to dark red. Edge of the labellum usually jagged (true N trilobus has a smooth labellum margin).

Flowering: August - December.

Habitat: Forests and scrub. Often forming large colonies.

Conservation: Not threatened. Common.

Notes: The name was use as a dumping ground for plants with kidney-shaped leaves with a mucro at the tip. Several species have now been separated but much variation remains.

Key features: flowers shovel-shaped, labellum often prominently striped over a cream inner surface or red margined along the very ragged lower edge which is split to two lobes (ears).
