International Aroid Society
Aroid is the common name for members of the Araceae family of plants, sometimes known as the Philodendron or Arum family. The sometimes beautiful and sometimes bizarre combination of spathe and spadix known as the inflorescence, and sometimes referred to as a flower, is a distinguishing feature of all aroids. The mission of the International Aroid Society is to provide information, assist in the distribution of unusual species and provide fellowship to everyone with an appreciation for this wonderful plant family.
