The spathe and spadix of Amorphophallus titanum by Kandis Elliot. What is an Aroid?
Aroid is the common name for members of the Araceae family of plants, sometimes known as the Philodendron or Arum family. The occasionally beautiful and often bizarre combination of spathe and spadix called the inflorescence, sometimes referred to as a "flower", is a distinguishing feature of all aroids.

You may have read that the IAS plans to discontinue offering a printed version of our quarterly newsletter. A timeline has now been officially set. The December 2022 edition of the IAS Newsletter will be the final printed version.

Beginning with the March 2023 edition, the IAS quarterly newsletter will be available solely online on this website. With the end of the printed version, the IAS has now unified the membership fee for all members, regardless of their geographic location.

Membership fees have dropped to $20 annually for individual members and $25 for institution/library subscriptions.
