unknown plant - please help

[easyr17]

hi everyone





(first pic is plant and second pic is closeup of leaf)

i am unable to identify which i hope someone here will know.

it is prevalent almost everywhere around town - car parks, friends front garden, roadsides, etc. - it mainly grows thru cracks in pavement, against a wall, etc.

Because i see it so often i am frustrated that i cannot identify it.

please help if poss.

One of thew Conyza fleabanes; looks like C. sumatrensis to me, which is now much commoner than C. canadensis in London at least. There are at least another 2 Conyza spp to look for but are much more localised.

I agree looks like Conyza sumatrensis. It is more or less the commonest plant around where I live.
