Aroideana is not available for purchase by non-IAS members until one year after publication. Every member receives a copy in the mail in August and this year will be our first to have color pages. I know that sounds unusual but the IAS is not a huge organization and we spend almost every dime we take in every year producing Aroideana and the show.
That's one reason I'm on a major push to increase the membership so we can do more color printing as well as grants to students going into aroid botany.
Every member also receives a quarterly newsletter with the next one out next month. The newsletter is always in color and is sent electronically.
If anything about my definitions is difficult just ask! I'll gladly do my best to "translate".
