Lovely example of persistence - over 9 years (2015 to 2024). In November 2024, its looking pretty much as when photographed back in November 2015; vegetative both times.
In his revision of Myriophyllum, Orchard (1985) says it often co-occurs with Myriophyllum integrifolium (and looks almost indistinguishable, according to his drawings). They can be separated with reproductive material: glomeratum has flowers and fruits are solitary in axils, where they are in fascicles for M. integrifolium. Perhaps if the habitat wets up and gives the plants a chance to flower, you could have a look for integrifolium ? ?
Any comments about the habitat and its water regime ? For M. glomeratum, Orchard describes it as winter-wet depressions, and seepages.

One of the plants has been collected as spirit specimen for ANH, accession no. CANB 1002305. Yes, it occurs in flat "swampy" when wet area, not necessarily winter-wet only, but has been under water through summer months at times. We continue to monitor
