I couldn't see the pic from the link you posted, so I went right into your photobucket in your signature line...
Was this the one[or one of the ones] you were talking about?
In that case, it looks like it doesn't have any roots... i had the same problem with mine..
I put some rooting agent on mine, and potted it back up... I haven't seen an improvement yet, but on the other hand, it hasn't gotten worse...
Mine would have been long-gone if it weren't for Margaret E. Pell... She's the best!
I hope she sees this, she'll be able to help!
Good luck with it!
