The plant family Araceae was named and described as such by Antoine Laurent de Jussieu in Genera Plantarum in 1789. The family is commonly referred to as the Arum Family and is the family of aroids.
As of when I last updated this page on 2-11-21, Plants of the World Online by Kew lists 140 accepted genera in this family.
The Missouri Botanical Garden in St. Louis, Missouri maintains the largest collection of Araceae in the world. There are many awesome experts specializing in this family and the Exotic Rainforest is an amazing site to visit. It is a privately-owned botanical garden in Northwest Arkansas specializing in members of the Araceae family. The website hasn’t been updated since January 2011, but it said their collection included 119 genera and nearly 3,700 species.
