Bidens aristosa looks pretty good. Here is a botanical description. http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=242416174

Hi Betty, Close but no cigar. Hauled my specimen out of the press. It definitely lacks the long bracts below the involucre, and the leaflets are sparsely to moderately hairy with short appressed hairs. An interesting thing I noticed is that each marginal tooth on the leaflets has a gland, which is visible on both leaf surfaces, and there is also one at the tip of each involucral bract. You'd reckon that would be a useful feature for ID, but only with access to a computer key, alas.

It looks like you will have to send it to Sydney.

Sighting information

  • Unidentified Scientific name
  • Unidentified Common name
  • Tura Beach, NSW Location

  • Website Reported via
  • Notes:
    The plant is multi-stemmed, not woody, about 1.5m high. Bidens is the genus that comes to mind, and images of Bidens aristosa on the web don't look too bad for it, but they have less evenly toothed leaf margins than this thing, and long bracts below the involucre, that my plant doesn't seem to have. It was growing on the edge of a pool, and Bidens aristosa is supposed to occur in "wet meadows" in the USA, and it is sold by nurseries.
