Haemantheae are a tribe of subfamily Amaryllidoideae (family Amaryllidaceae). They are herbaceous monocot perennial flowering plants with a predominantly African distribution. Three subtribes are proposed and six genera including the type genus, Haemanthus, are included. They are characterised by the presence of baccate (berry) fruit.

Subdivision

There are three subtribes, with six genera

• Cliviinae D.Müll.-Doblies & U.Müll.-Doblies
• Haemanthinae Pax
• Gethyllidinae Meerow

The subtribes are related as follows:

Tribe Haemantheae	Subtribe Cliviinae       Subtribe Haemanthinae     Subtribe Gethyllidinae

Cliviinae: Two genera - Clivia, Cryptostephanus

Haemanthinae: Type - two genera, Haemanthus, Scadoxus

Gethyllidinae: Two genera - Apodolirion, Gethyllis
