Interesting find Greene about the 'Catalogue of Life' listing Pseudogynoxys chenopodioides as native also to S-E Brazil with the notation of the 'Flora do Brasil'!
I've looked again in there and it is still not listed..?
Could you give me your link to the site where you found it, not sure if I'm using an old list..
No Beverly, the 'Flora do Brasil' also mentions plants which have naturalized but are not native to Brazil like f. ex. Impatiens walleriana..
