Curly Flat-Sepal Pterostylids
By Ian St George

Here are a few copies from my unruly slide collection, of Pterostylis montana or something similar.
They illustrate my perception that flat lateral sepals may sometimes curl - it's in the nature of ribbon-like structures to curl. I don't think the curl of a flat lateral sepal should be regarded as a diagnostic feature.

1. The plant illustrated at top left is the typical bronze-coloured, short, upright-leaved, grassland plant with the bulbous stigma in an upright flower: almost certainly self-pollinated; very common around Dunedin, Wellington and the Wairarapa
2. Horse Range north of Dunedin
3. Aorangi SFP southern Wairarapa
4. Airlie Rd, Plimmerton, Wellington
5. Airlie Rd, Plimmerton, Wellington
6. Maungatapu, Taieri, Otago
7. Almost achlorophyllous P. banksii, Kaueranga, Thames
8. Mutant form, Upper Morrisons Creek, Leith Valley, Dunedin
