Goody or baddy? Roughly 2x2 metre patch. I will go and pull it out if required.

Is it Dysphania pumilio? There seems to be a perennial form as well as annual plants common this year.

I agree with Mike. There are other recent photos on CNM very similar to this one.

Thanks for that. Yes it looks very much like Mike's Isaacs Ridge sighting on 25 April 2019. Kind regards, Roy.

Mike's confirmed Dysphania pumilio (4207824) at Isaacs Ridge is very doubtful. This one is not like any Dysphania pumilio I have seen.

I've added 3 more photos, but I'm sorry, my camera isn't very good for a close up.
The specimen has a vibrant green appearance and reddish looking stems, a bit like rhubarb.
Cheers, Roy.

Thanks Roy - this is very helpful. Photo #3 shows the leaves. It is definitely not Dysphania pumilio.

There are several species of Dysphania in SE NSW which have fruiting bodies like this. I think a specimen needs to be taken to the Botanic Gardens for a proper identification.

I made my first visit to the CSIRO Herbarium today and successfully dropped off a sample. Cheers, Roy.

Dave Albrecht said "Roy - Your ‘Crumbweed’ specimen found its way to me for identification. It appears to be Dysphania multifida (Scented Goosefoot). See the following links for further information https://vicflora.rbg.vic.gov.au/flora/taxon/fac28f72-b830-4390-9c5e-0f751df5ed8e and https://keys.lucidcentral.org/keys/v3/plants_se_nsw.old_2019_01-11_delme/key/plants_se_nsw/Media/Html/entities/dysphania_multifida.htm.

Its a weed Roy - so feel free to pull it out next time you are up there

Does this also apply to the ones on isaacs Ridge? I looked the other day and couldn't find any of the deeply dissected leaves, only a few tiny linear ones among the flowers and seeds. The plants seemed to be dying back so I don't know if they are perennial or not.

I pulled it out today (pretty easy, no prickles). I just need a second go at the tap root. Cheers.

Thanks Roy - very impressive wiping out a whole species of weed from Red Hill

Mike check the references given by Dave, I think smell is one deference and pull out if the weedy one - can you change the iD to if needed
