I have been looking at the monographs in Flora of Australia http://www.anbg.gov.au/abrs/online-resources/flora/main-query-styles.html Without at least female flowers I don't think it is possible to separate M. simulans and M. variifolium.

Thanks Betty, sorry I forgot to add in the image for the female flowers, unfortunately it is not the best quality. I went with the descriptions in PlantNET; M. simulans often has male and female flowers on separate shoots as this example has, whereas M. variifolium has the flowers on the same shoot. Also the extent of teeth on some of the leaves (2nd image) and arrangement and number of leaves on the stem tends to be more like the characteristics described for M. simulans. However the stigma colour, from what I can make of it tends to support M. variifolium. I don't know if the additional image will help or not, unfortunately I'm often at a loss when a specimen has contradictory characteristics.

I tend to go on what the key characters are. As you know, Vicflora and Plantnet use the same key, and Flora of Australia has not yet released any keys at all on line. The keys really go on the colour of the fruit and the colour of the stigmas, as well as the number of leaves in a whirl . I cannot tell from the photos whether the leaves are in whirls of 4 or 5. Can you tell me that, and also what colour the stigmas were - white, or pink fading to white? At present I am tempted to call these photos Myriophyllum sp.

I suspect Myriophyllum sp. might be the best option it seems there are whirls with either four or five leaves and in some instances the distribution of leaves is more irregular. From what I can make of them the stigmas are only white, I see no evidence of any colour.

I suspect that if a cladistic analysis is done that M. simulans and M. variifolium will be merged into the same species again.
