==Ragweed== 
 Zwobot just added a bunch of interwiki links that had been removed manually recently. Some of the articles (e.g. de:Beifußblättriges Traubenkraut) are on the species Ambrosia artemisiifolia while en:Ragweed is about the genus Ambrosia. The bots are really cool, but once we have some wrong interwiki links they propagate quickly and they are hard to get rid of. Kinda like ragweed, actually -).
