A reminder that even in the more backwards Anglophone countries where gray is misspelled "grey" as a matter of stubborn pride, the surname of the great American botanist (and correspondent with, inter alia, Charles Darwin) is GRAY. ASA GRAY Not Asa Grey, as it was recently misspelled on one of the English news web sites.
