Hi Richard

It is difficult from photos accurately to determine many plants.
My book, admittedly written from a European perspective, gives
the following characteristics to look for in a Freesia:

-Slightly irregular, 6 petal (strictly 3 petals and 3 very
similar sepals) flower with 3 stamens (your photo appears to have
6 stamens); style usually 3-branched.
-Style branches narrow (not petaloid)
-Few to many flowers on stem, in spikes or panicles (not at end
of stem like crocus)
-Plant with a corm (as shown in one of Loosescan's photos)
-Style 3-branched, with each branch bifid (split in two)
-Bracts 1.5cm; spike bent horizontally near lowest flower;
flowers on one side of stem; leaves soft; wingless seeds.

From this description (Stace New Flora of thee British Isles), I
suspect that your plant is not a Freesia. Sorry - I cannot tell
you what it is.

You are right - the flower is scarlet.

I agree the search must go on.

To assist this I have posted a photo of the flower that shows
more
detail.

The length of each petal is 9 mm. Note the brown base to the
three
lower petals.

Perhaps a Fressia laxa

Thanks. This is definitely the species.

The pictures of Freesia laxa (see URLs above) are identical to my
plant. However on pursuing the matter further I find that this plant
has been removed from the Freesia genus and renamed Anomatheca laxa.
So perhaps that reconciles things.

Furthermore the plant is naturalised in Sydney, where I saw it
growing:
