I'd be grateful for people's opinions & help in naming these few;

1: Looks like a Chenopodium, but if it is I can't figure out which



2: Having looked at it again, I now think this is just a variant of Yellow-sorrel (Oxalis corniculata). But I thought I'd see what others felt anyway



3: I'm pretty sure this is a spindle Euonymus sp., although it didn't have a single fruit of any description on a tree of about 15ft high. It's without a doubt the most vivid red leaves I've ever seen;



4: A species of mallow, obviously, this one sprung up at the alien hot-spot of Abbey Wood Station, Filton, and is still in flower now. Note the hairy stems in the (not very clear...) close-up;



5: The flower on this one makes me think of a Chenopodium sp and the closest I've got is Mexican-tea (Chenopodium ambrosioides)...
