Hi Michael Isobel Crawford id-ed Erodium botrys from a collected specimen. E. botrys it has the longest "bill" of all introduced Erodium as far as I know. id leaves not pinnate Pits at base of awns glabrous K (calyx) hairs glandular predominantly leaves not three-lobed awn more than 8.5 cm (mature)
M there might be a mixture of both E botrys and E cicutarium but the very long fruits are of E botrys; we have all three introduced Erodium at this disturbed and overgrazed area; the third species is E moschatum. A photo of E cicutarim taken earlier in the paddock is at https://majura.org/friends-of-mount-majura-fomm-newsletter-september-2020/ I may go and take photos of all 3 introduced species for comparison - I'm pretty sure that there are still many around after our hand weeding sessions...
