Oh OK, if I must lol ... but that is more of an exercise in research on the web rather than problem solving. I'll give it a go later when I've got a few minutes.
Found one ... Euphorbia
Found another ... Magnolia

In the meantime ... bringing forward (again) ....

Fred was trying to sell his safe to Bill, a prospective buyer.
"I see it is one of those new fangled digital ones with a 10 digit combination. How did you decide on the combination?", asked Bill.
"It's a long story," replied Fred, "I multiplied my age by my grandmothers and then added, my house number, the three digits from my car registration, how many tunes I had downloaded for my iPod and the number of games I'd played on FunkySnooker. I was running out of ideas so I tripled the result but still didn't have enough digits. After a little thought I squared the number and just at that point a No. 81 bus went past so I thought 'what the hell' and added that in too. About a week ago, I changed the number by writing down the combination, cutting out each of the digits and placing them in a bag from which I drew out each of the digits at random. I then burnt the pieces of paper."
"Wow," said Bill, "that was complicated. I think I'll take it after I have a look inside. What's the combination?"
Bill goes to the safe and Fred starts ... "6... 3...1... 7... 6... 4... 9... 1... 3... "
Before Fred had time to give the last digit, Bill had punched it in and opened the safe. "That was a lucky guess!" exclaimed Fred. "No it wasn't" replied Bill, smiling.
How did Bill know the combination and what was the last digit?

before i whip out the pen and paper, is this a puzzle where the answer is hidden somewhere or is it purely mathematical?

Not entirely sure what you mean by hidden somewhere but it is definitely mathematical in nature rather than number/word substitutions or number of letters or double meanings etc.

Em, the last digit was 8, from the 81 bus that went past

Sorry no, iamtheworst tried that one too earlier:
No sorry, that is also incorrect. He did in fact add the 81 to the number in the usual manner.
If you know how Bill knows, you would know if it is right or not

iamtheworst said:
Buddytobud, last digit was 8? Because of the 81 bus? If I read it correctly, he just put 81 on to the end of the 8 digits he already had?

3 is the wrong answer anyway ... but I don't really want people to try each of the 10 possibilities

Where's the 8 gone then? He didnt change the combination after adding the " 81".
He didnt do anything expect mixed them up and put them in a new order.
So where is the 8??

As I said to worst, he did in fact add the 81 to the number in the usual manner i.e. by addition and not by simply putting the digits on the end of the number.

I may look very stupid but I think I've got it.
That had better be right bud.
The last digit is a 5.
Some number was multiplied by 3 then squared, meaning the result was a multiple of 3 squared = 9. Then 81 (or 9x9) was added meaning the result was still a multiple of 9.
Now if you add the digits of any multiple of 9 then they add up to a multiple of 9.
6+3+1+7+6+4+9+1+3=40
The next multiple of 9 is 45 and no other multiple of 9 can be reached by adding a single digit. Therefore the missing number is 5.
The order of the other numbers is actually irrelevant thanks to the commutative nature of addition.

Couldn't track down any more before losing interest lol (though one or two came very close) so you might as well let us know.
