Hi
I am just hoping someone could assist in identifying the weed in the attached photo. It is proving very difficult. I have tried asking a horticulturist from a common supplier of weed poisons without success. I live on the Central Coast of NSW and over the years it has become quite prolific around the area. Any advise on what it is and how to control it would be fantastic.

Looks like Richardia weed or something in rubiaceae. I suggest it could be Richardia humistrata Synonyms: Richardsonia humistrata.

Thank you for your help tofitropic, that is certainly what it is and apparently it can be controlled with Dicamba. Once again thank you for your advice.

I agree, Richardia of some sort. There may be a few that grow in your part of the world but two that come to mind are R. brasiliensis and R. humistrata.

If the flowers have 6 petals, maybe Tropical Mexican Clover (Richardia brasiliensis)

If the flowers have 4 petals, maybe R. humistrata:

I would not be attempting to control richardia with poison...
richardia is a valuable butterfly plant, providing nectar, and is a host plant for the tersa.
also... the chickens love richardia!

Any chance the plant is mauka?

It doesn't look like the Mirabilis I'm familiar with and I see we don't yet have photos in the database for Mauka (Mirabilis expansa) so, if it does turn out to be M. expansa, I hope you will consider uploading a few photos to the entry.
