it is self seeded ,rooted in brickwork.It has hard thorns up the stem if
the picture is enlarged .soft thorns can be seen running up the under
side centre of the leaf.Ihave never seen anything like this plant and
ive searched archives from kew and various other sites,i found nothing
closely resembling this plant, can anyone advise me what it is where it
comes from and if it is poisonous .heres hoping dave
