Aroid Stamps
There are a lot of stamps out there. About 10,000 new types of stamps are published each year, and there are some 400,000 different types in existence. Many of them feature beautiful or interesting plants, and some of those plants are Aroids.

Marek Argent in Poland has a large collection of aroid stamps online as well.

If you have a scan of an aroid stamp, and would like to contribute to this page, please let Albert Huntington know.
