These plants are trees or shrubs. They usually have single or paired white or yellow flowers, but some species have larger inflorescences. The fruit is a hard capsule with winged seeds.^[3] The winged seeds make the genus distinctive in its family.^[5]

The former Madagascan genera Helmiopsiella and Helmiopsis are now considered synonyms of Eriolaena.^[1] These genera were named in honour of C. Helm, German clergyman in Berlin and amateur botanist.^[6]
