In 2005, cycad officianados Tim Gregory, Jody Haynes, and Jeff Chemnick created a wonderfully illustrated poster and identification key that summarizes the vegetative traits that are most useful in identifying the known species of Dioon (see below). Originally presented at the 7th International Conference on Cycad Biology (CYCAD 2005) in Xalapa, Veracruz, Mexico, this one-of-a-kind poster (which measures 24" x 36") has been printed on heavy glossy paper and made available for sale by TCS.

Proceeds from the sale of the posters will go toward cycad research, conservation, and/or education.
