Ms. Vic, I don't know what pine you have, but I think 'pinus on standard' would mean that it's grafted onto different rootstock (the 'standard'). Weeping Japanese maples are commonly described as 'grafted on a high standard', i.e. the rootstock is tall (high) to allow it to weep. In your second picture, it looks like the graft union is halfway between the roots and the first branch. (Or I could be mistaken.)
