The name of this botanist comes in different variants: 'Carl Linnaeus', 'Carolus Linnaeus' and 'Carl von Linn\ufffd', sometimes just 'Carl Linn\ufffd'. There is often confusion about his real Swedish name, as opposed to the Latinized form 'Carolus Linnaeus' he used most when he published his scientific works in Latin.
Maybe they should just have an ISFN (ala ISBN) instead. :-)
Cheers,
Scott.
