Plant: very variable, up to 10mm thick at its base, leaf tubular with a flower spike up to 1 m tall in fertile situations (usually much less).

Flowers: green, many, closely packed, tiny, with pointed, hooded dorsal sepals often half enclosing the narrow petals. Lateral sepals pointed and curled. Labellum oblong, irregularly scalloped, often narrow at middle; margins irregular; apex often notched but not apiculate; apical callus variable, warty; basal calli oval, prominent.

Conservation: common, often abundant, not threatened.

Notes: A plant with a huge range in size such as the example here. The constant features are the very ornamented labellum and large basal calli. Autumn flowering plants are structurally similar.

Key features: very ornamented labellum margins, single prominent basal callus.
