hey hebe, it was Zornia dyctiocarpa, an Aussie native Zornia species (found it growing in my lawn), believe there is another one or two species around the country as well, one up in the NT. To me it smells spicier than Z. diphylla, almost makes me sneeze. Sound slike it might be bettere than diphylla, i had similar effects from diphylla. Thanks for sharing.
