Pterostylis humilis
(low growing - a misnomer, the species was described from dwarfed cultivated plants)

Leaves broad, in a semi-rosette.

Flower erect, sepals shortly acuminate, the lateral barely exceeding the galea. Labellum-tip constricted, stigma very large, globose.

This is the only orchid I have ever seen actually flowering in the snow.

Distribution - endemic - in subalpine scrub. North Id. Mount Egmont, the Volcanic Plateau, and east to the Kaimanawa Ranges: South Id. Sounds/Nelson district

Flowers - December-January - self pollinated

Pterostylis venosa
(the conspicuous veins on the leaves, the plant was
described from dried material)

A semi-rosette plant of alpine scrub.

The labellum is narrow-triangular, and sometimes furry.

Distribution - endemic - North Id. Mount Egmont southwards (like irsoniana, apparently absent from Ruapehu): South Id. Stewart Id.

Flowers - December-January - insect pollinated
