Dais glaucescens, commonly called havohoa in Malagasy,[2] is a species of flowering plant in the family Thymelaeaceae that is native to central Madagascar.[3] It was originally described by Joseph Decaisne in the Annales des Sciences Naturelles in 1843.[4]

Description

Dais glaucescens takes the form of a shrub or small tree, growing up to 8 metres (8.7 yd) tall. The trunk can be up to 25 centimetres (9.8 in) in diameter.[5]

Distribution and habitat

Dais glaucescens is native to the central areas of Madagascar. It is found in forests, usually near water, at elevations of roughly 1,000 metres (1,100 yd).[5]

Uses

In Madagascar, the bark of Dais glaucescens is known as "havoa" and is used in the making of Antemoro paper.[6] This practice of using the "beaten-bark technique" has been attributed to the Antemoro people as far back as 1661 by the French governor of Madagascar Étienne de Flacourt.[7]
