Recorded distribution

Plant

To 50 cm tall, reddish tinged, very erect with both flower and leaves upright. Leaves short 5-25 cm x 1-15 mm, and clasping the stem.

Flowers

Lateral sepals short, scarcely longer than dorsal narrowly separating from the dorsal sepal and erect. Labellum tapering, reddish, peeping through a narrow V sinus. Stigma heart-shaped. Ovary ribs orange.

Flowering

October - November.

Habitat

Lowland to subalpine, damp scrub and forest. South to Hokitika.

Conservation

Never numerous, often only a few plants at any locality.

Notes

Named for its lobed, heart shaped stigma. Distinguished from budding P. banksii by the upright clasping leaves and small opening to the flower with narrow, protruding labellum. The sepals may turn forward somewhat to be less “upright”.

Key features

Upright stance of reddish plant with leaves prominently clasping the stem, labellum poking out from the small aperture between the tepals, heart-shaped stigma. Leaf midrib and ovary ribs generally have an orage hue.
