Nostalgia

Two parts of a cross      
And a circle complete
Two semicirculars, perpendicular meet
And a triangle standing on two feet
Two semicirculars
And a circle complete
That spells ....what?
I had forgotten a chap was still growing some in the Motueka Valley. So driving past today was a nice surprise and I remembered the above song we sang about it.Once it was the main crop grown in this district but had all but disappeared by 1996.
I'll add tags later.
