A bit hard to tell but the leaflets don't look particularly stalked, either way this won't be G. tabacina

Most of what I have is stalked although some like this this one are pretty close to sessile. So I guess most are G. multifida. But if this one isn’t G. clandestina, I figure I have some. I have loads of glycine.
What are the distinguishing characteristics of tabacina?

Leaflets stalked rules it down to G. tabacina or microphylla - microphylla is twining like clandestina (it climbs up things, unlike the trailing tabacina which tends to be more of a sprawling plant), however it can be further separated from tabacina by the narrower leaflets (length:width ratio of 2–7:1 from VicFlora) and the three leaflets are usually the same length, whereas tabacina has broader leaflets (length:width ratio of 1.6–4:1 from VicFlora) and the terminal (middle) is usually also longer

I think this should be G.tabacina from what I can see, based on vein reticulation (looks to be 60-45 degree), plus the terminal leaflet is clearly longer. It is not possible to identify wheather or not plants are trailing or twining here; there are not enough characteristics visbile to say either way. I don't think relative leaf width ratio is a strong character to ID off images given the absence of appropriate scale.

Hmm okay, back to the drawing board for me. I find the differentiation of these two can be a bit of a mindgame in some situations, they seem to have a fair bit of overlap.

Lisa, have a quick flick through the Vicflora key. It should hopefully clear some things up? But i can go through these group with you at some stage also, whenever I next see you :)

Ciaran - if you need better photos, let me know what you need and I’ll try, but you must be ok with it because you approved it. I would like to get a handle on the pea plants occurring on the property.
Likewise, the geraniums but I’m afraid to go there.
