I did what I could.  99% of my problem with EGGs is that I could not find one simple article (or article section) that described old volcano areas in general.  Each area like this seems to have its own description and the only specific area that I needed for the article was Mount Etna  it is all about places that resemble those regions  growing conditions.  Short of writing that article as well (which would be interesting but I have been trying to tackle Senecio and the article about the alkaloids (which can and should be greatly improved)).  I would rather keep spitting out new species pages and I am also looking for information for an article about Paul Klee's Senecio (painting) which are all related to the article about the alkaloids.  Even the geology and soil science pages that I looked at don't have general information which is specific to these regions.  All I know is that they probably all grow potatoes, but I don't know why and don't want to until this alkaloid mess is settled  which I am almost euphoric to write!  I found a paper that I had been citing a citation of a citation to in the mid-nineties (in the middle of hauling volumes of plated food out to families and truckers).  It is that kind of euphoria, one of the closure of a large "I read somewhere that they read somewhere that a paper was written that cited a paper and what they really said was...." open-end from previous studies.  

Can I blame it on the soil scientists?
