Wrong maple leaf on Canada's 20 dollar?

A few days ago I wrote about the Canadian polymer banknotes which faced with all kinds of criticism and complaints. From serious ones to the more ludicrous. The list seems to grow longer every day. And now a new complaint has been made about the 20 Dollar note.

Sean Blaney, senior botanist of the Atlantic Canada Conservation Data Centre, claims that the maple leaf shown on the banknote is not the sugar maple (which is featured on the national flag) but in fact the Norway maple.

"It's a species that's invasive in Eastern Canada and is displacing some of our native species, and it's probably not an appropriate species to be putting on our native currency," Blaney told CBC News.

The central bank said the image on the new bills was purposefully designed not to represent any specific species but rather to be a combination of various kinds. "It is not a Norway maple leaf. It is a stylized maple leaf and it is what it ought to be," said Bank of Canada currency spokesman Julie Girard. Mr. Blaney doesn't buy this explanation and thinks the Bank has made an error.

Below are both leaves. On the left is the Norway maple leaf and on the right is the sugar maple. So who's right?
