Hi, Jane, if you have pictures of the other less aggressive species it would be nice to have them on the wiki. I noticed on the web there are various ways of spelling used for the yellow flowered species. Jane spells it one way (Lysichiton americanum), but when I looked it up on IPNI and Mobot it was spelled either Lysichiton americanus or Lysichitum americanum although Mobot seemed to prefer the former. My field guide and some of my books spell it Lysichitum americanum. Kew only lists Lysichiton americanus and doesn't even have a synonym listed under the other name. The dates and references for both spellings on IPNI are the same. Can anyone explain about the history of the name or add clarification?
