Flower id please!

[Imicola]

Hi all. Any ideas on what this flower is? I'm presuming it is a bulb /corm as it seems to have spread over a large patch of garden, with little interference (that's my kind of plant!). It's been flowering since September.

Hesperantha than I think? It's pretty!

That's it, thanks! It is very pretty. I wasn't a million miles away as in my head I had a word that begins with s and has a z in it... And the other name for it is scizostylis! Going to lift some and move to our sparse front garden.

Good idea, happy gardening to you!
